Why Clean Air Ducts Could Make You Breathe Easier

Clean Air Solution by Camfil USA. Leader in Air Filters for Commercial and Industrial applications.

Dead skin, hair and pet dander, dust and bacteria are all lurking in your HVAC system. Clean air ducts can prevent respiratory problems and help you breathe easier.

The heating, ventilation and air conditioning (HVAC) system in a home or workplace not only delivers the air that helps regulate the temperature and humidity, but it can also determine the quality of the air that you are breathing. That’s because the outdoor air that is drawn through the HVAC system, and recirculated are filled with dust, dirt and other particles that compromise the quality of your environment.

That’s why clean air ducts are so vital to keeping your HVAC system operating at peak efficiency, but unfortunately, a lot of people just don’t understand how dirty ducts can affect their long-term health, or even how to go about having their ducts inspected.

Is Your AC Making You Sick?

If you or someone in your family has persistent allergies or respiratory problems that don’t seem to have an identifiable trigger, you may want to ask this question: Is your air-conditioning system making you sick?

To understand how this could be possible, it’s worth understanding the basics of how ducts work in an HVAC system.

According to HVAC for Beginners, a duct system provides a controlled path for airflow throughout the home. The system can be made out of sheet, metal, fiberglass ductboard, insulated plastic, or cloth.” (1)

Ducts are simply an air distribution system to circulate cool and warm air through a home or commercial facility.

A duct system has a supply side that distributes conditioned air through the vents in each room, and a return side that sucks air back into the air handler of the HVAC system so that it can be conditioned again and circulated back through the supply side. Ducts are typically rectangular or circular.

The problem is that all that circulating air draws in pollutants such as dust, pet hair, bacteria, dust mites, and pollen, which can become trapped in the ductwork, including the vents, motors and coils.

Once trapped in the ducts, these pollutants are expelled through the vents, filling a home or workplace with harmful pollutants. And the bigger problem is that dirty ducts can go unnoticed for years, which just increases the level of airborne contaminants.

And these contaminants can worsen asthma symptoms, and make allergies worse if they are not eliminated. That’s why clean air ducts are so important.

Signs Your Air Ducts Need Cleaning

But since ducts are out of sight and hard for a non-professional to inspect, what are some of the signs your air ducts need cleaning?

According to Angie’s List, one sure sign that your ducts are dirty is the visible buildup of dust, pet hair and dust on the outside of your air vents. (2)

Another sign your ducts need cleaning as if dust blows through the vents when the air conditioning comes on. That means the debris from the ducts is forcing its way through the vents, which is not a good thing, because all of those pollutants are now circulating in your home.

You can also check the condition of your air filters to see if they are extremely dirty, which could mean that they are working much harder to trap dirt from the duct system. Furthermore, you can also check to see if there is reduced airflow from your vents, which is a sign that not enough air is blowing through the ducts because of dirt blocking the air filters or otherwise restricting airflow.

Choosing an Air Duct Cleaner

When choosing an air duct cleaner, one of the most important considerations is to select a company that is a member of the National Air Duct Cleaners Association (NADCA).

This association requires all members to have a certified Air System Cleaning Specialist on staff that has passed the NADCA certification exam. (3)

The U.S. Environmental Protection Agency (EPA) also suggests that you don’t hire any company that claims to be endorsed by the EPA, as the agency does not certify air duct cleaners. In addition, the EPA strongly recommends that you check the references of all prospective air duct-cleaning companies and that you obtain a written agreement that details the total cost and exact process of the cleaning before signing the contract. (4)

Benefits of Air Duct Cleaning

Clean air ducts can provide your home with multiple benefits. First, it ensures that any residual moisture in the ducts is removed, preventing the formation of mold, which is not only a health hazard, but is very expensive to remove once it grows in the HVAC system. Second, it improves the efficiency of your HVAC system, which can save money on your power bills. Third, it helps improve indoor air quality by removing harmful pollutants. One other thing you can do is install high-efficiency air filters to ensure that a majority of the airborne contaminants in your home are eliminated.

What Is Sick Building Syndrome and Why Should You Care?

Clean Air Solution by Camfil USA. Leader in Air Filters for Commercial and Industrial applications.

Sick Building Syndrome is causing respiratory illnesses in millions of Americans, and very few people understand that where they work could make their life hell.

Understanding Sick Building Syndrome

The U.S. Environmental Protection Agency (EPA) defines Sick Building Syndrome (SBS) as, “situations in which building occupants experience acute health and comfort effects that appear to be linked to time spent in a building, but no specific illness or cause can be identified.” (1)

SBS does not always originate from an entire building and can be localized to a particular area or even one room. The reason understanding SBS is so important is that a majority of adults spend a minimum of eight hours a day inside an office or work building, and most people in the U.S. are indoor for about 90 percent of the time that they are awake.

Sick Building Causes and Symptoms

Although SBS does not have one specific cause, researchers have found that a combination of factors may be responsible for this syndrome. These factors include:

Lack of proper ventilation – if a building is not adequately ventilated an insufficient amount of outdoor air is flowing through the building and contaminant levels remain high because they are not diluted.

Chemical pollutants –emissions from office equipment and other products such as cleaning materials can create a noxious environment, which the World Health Organization (WHO) has identified as significant contributors to adverse health.

Biological pollutants – this includes airborne bacteria, viruses, pollen, mite feces and pet dander. Standing water in buildings or wet surfaces can also create mold and mildew that compromises indoor air quality.

“The latest studies on Sick Building Syndrome has found that mold that growth in buildings can become airborne and produce mycotoxins that are easily inhalable or swallowed,” stated Kevin Wood, Camfil USA Vice President Sales & Marketing. “These mycotoxins can burrow deep into the lungs and respiratory tracts and cause serious ailments.”

Mycotoxins are poisonous compounds that are produced by the fungus. When ingested, they can weaken the immune system and irritate the nasal passages, worsening breathing ailments such as asthma.

People who have SBS will commonly report symptoms such as:

Headache

Dizziness

Eye, nose and throat irritation

Hacking cough

Skin irritation

Loss of concentration

Fatigue

Nausea

And according to the Environmental Illness Resource, it’s important to remember that these symptoms are only identified as SBS if they disappear shortly after a person leaves the building.(2)

Understanding the causes and symptoms of SBS, can not only help workers and building managers take steps to resolve the problem, but also drive home the importance of good indoor air quality in commercial buildings.

What Is Indoor Air Quality?

Most people are aware of outdoor air pollution, but fewer can answer the question: What is indoor air quality level at my home or work? The reason is that it’s much easier to see, smell and understand outdoor air quality, but more difficult to assess indoor air quality.

According to the EPA, indoor air quality, “refers to the air quality within and around buildings and structures, especially as it relates to the health and comfort of building occupants.” (3)

Pollutants within a building can cause employees to miss work due to respiratory illnesses, which affects productivity and costs companies millions of dollars in lost manpower.

Sick Building Syndrome Treatments

If enough people working in a commercial building begin to show symptoms of SBS, building supervisors can implement several SBS treatments to alleviate the problem. First, they should inspect the building to ensure that there is no mold. Second, they should inspect the HVAC system to ensure that the ducts are clean. If the ducts are not clean, building supervisors should hire a professional to clean the ducts. Third, any chemicals housed in the building should be sealed and stored in well-ventilated areas.

One final SBS treatment is to ensure that dirty, old air filters are replaced with filters that have a published efficiency consistent with a high level of removal of dust, mold, pollen and bacteria in an indoor facility. This is an essential step in controlling SBS and reducing the onset of adverse symptoms.

Why Rising Air Pollution Will Kill You

Clean Air Solution by Camfil USA. Leader in Air Filters for Commercial and Industrial applications.

Rising air pollution levels is causing lung cancer, heart disease, and worsening asthma. It is also cutting short life expectancy. What’s to be done about this worldwide crisis?

Rising air pollution levels throughout the world are not just an environmental concern. Scientists have known for decades about the link between worsening air pollution and an increase in the risks for heart disease, lung cancer, and reduced lung function. But it’s only recently that the link between air pollution levels and life expectancy has become more obvious. And that link is stronger in poorer countries, because of lower air pollution control standards, and the lack of sufficient health care to battle the illnesses caused by poor air quality. This is an issue that affects everyone because pollution is a problem in nearly every country in the world. Therefore, it is important to understand how pollution directly shortens lifespan, and how to improve outdoor air quality.

Also Read our blog on : The Surprising Impact of Air Pollution on Exercise

Why Air Pollution Cuts Life Expectancy

The reason why air pollution cuts life expectancy is that the particles that are released into the air are very toxic.

According to News–Medical.Net, a new study by researchers in Denmark has found that, on average, an increase in pollution particles in the air of 10 micrograms per cubic meter cuts victims’ life expectancy by 9-11 years – more than previously thought.” (1)

The Denmark study used a sample of 100,000 people and their estimated mortality rates by age. Researchers then simulated the effects of long-term exposure to increased air pollution (of 10 micrograms of small particles per cubic meter) on mortality.

The study found that the average age of an air pollution victim is 78.9 years and their average loss of life expectancy is 9-11 years – much longer than a frequently cited estimate of 1-2 years.

The particles that were used to simulate the effects of long-term exposure to air pollution are commonly known as particulate matter (PM), and they are formed from emissions generated by vehicle exhaust, coal-burning factories, smokestacks, fires and construction activities.

Some forms of PM such as dirt, dust, and soot are visible to the naked eye, but others are very small and cannot be detected except under a microscope.

And it is these invisible pollutants, categorized as PM10 (particles 10 micrometers or smaller), PM2.5 (particles 2.5 micrometers or smaller) and PM1 (particles 1 micrometer or smaller) that pose the greatest health risks because they are easily inhaled and swallowed and can lodge in your lungs.

PM has also been linked to heart and lung disease, irregular heartbeat, decreased lung function, worsening of asthma symptoms, and difficulty breathing.

Given these realities, countries throughout the world are struggling to find ways to lower rising air pollution levels.

Reducing Emissions of Air Pollutants

Reducing emissions of air pollutants is a long and difficult process, but countries such as India have started taking steps to improve outdoor air quality.

According to a World Health Organization (WHO) report, India’s largest sources of rising air pollution are indoor cooking stoves, traffic congestion, and industrial factories and plants that burn fossil fuels. Another more intractable source of pollution is the common practice of burning waste in the open. (2)

To reduce emissions, the Indian government has initiated a clean air campaign that includes proposals to shift residents to clean energy sources (such as solar power) for indoor cooking stoves, public transport, and industrial processes.

Furthermore, the government is trying to lower vehicle emissions by increasing fuel taxes and parking fees and establishing no-car zones to encourage walking and bicycling.

“India is the perfect example of a country that is taking big steps to reduce its harmful emissions,” stated Kevin Wood, Camfil USA Vice President Sales & Marketing. “You have to go to the source of the air pollution problem and find ways to lower a number of contaminants that are generated. Improving air quality is a challenge, but it is not without real solutions.”

Protecting Yourself from Air Pollution

With rising air pollution becoming a problem across the globe, protecting yourself from air pollution is vital to your future health and perhaps even to your life expectancy.

To reduce your exposure to bad air, make a habit of checking the U.S. Environmental Protection Agency’s (EPA’s) Air Quality Index, which gives you a daily measurement of harmful pollutants. That can help you limit your exposure to outdoor pollution, especially if you have asthma. You can also invest in air purifiers for your home or workplace to eliminate particles that are bad for your health. And finally, you can ensure that your HVAC system has high-efficiency air filters that can also trap many common pollutants before they can be inhaled or swallowed.

What the Heck Are HEPA Filters – And Why Should You Care?

Clean Air Solution by Camfil USA. Leader in Air Filters for Commercial and Industrial applications.

HEPA filters have existed since the early 1950s and are the most effective filters you can buy. They are an important component in the effectiveness of any air filtration system that claims to provide comprehensive elimination of harmful pollutants,” stated Kevin Wood, Camfil USA Vice President Sales & Marketing. “In basic terms, these filters are rated to trap a higher percentage of very small particles than most common filters on the market, which means better indoor air quality, and better overall health, especially for people suffering from chronic allergies and respiratory problems.”

An air filter’s main function is to remove airborne pollutants from the air that circulates through our offices and homes to protect the buildings occupants 1. A HEPA filter is so effective it is the main line of contamination defense in hospital operating suites, protecting doctors, nurses, staff and of course the patient on the table. They are also used in commercial applications that have a defined extreme cleanliness level (commonly called clean rooms) where microprocessors and pharmaceuticals are manufactured. Without HEPA filters there wouldn’t be any clean rooms; no cell phones, no televisions, and none of the pharmaceuticals we produce to make life more comfortable.

How HEPA Filter Are Different

HEPA is an acronym for high-efficiency particulate air filter. Its original name was high-efficiency particulate arrestor, titled so by the US government when they were developing the filter during the manufacture of the original atomic bomb (the Manhattan Project)2.

To be a true HEPA filter the delivered product must have been individually tested as to its efficiency and airflow and serialized on a label on the filter by the manufacturer. There are different classes of HEPA filters with increasing levels of efficiency but the minimum level of efficiency must be at least 99.97% efficient on particles 0.3-micron in size. This particle size is 0.000012 of an inch, which is about 300 times smaller than the diameter of a human hair. To a HEPA filter, catching a one-micron size particle (1/1,000,000 of a meter) is the equivalent of stopping a cotton ball with a door screen.

It is important to note that 0.3-micron was selected because it was believed to be the most penetrating particle size of a filter and if the filter has a high efficiency at 0.3-micron its efficiency will be greater in other ranges. In a typical atmospheric air sample, there are hundreds of thousands of these particles in a single cubic foot of air.

Why Should HEPA Filters Be Considered Important

The United States Environmental Protection Agency (EPA) publishes data for US cities in terms of the size of particulate matter (PM). The three common levels are PM10 – particles 10-micron or less, PM2.5 – particles 2.5-micron or less, and PM1 – particles 1-micron or less3. PM1 is the most common by count of all particles in the air as that is the range where 99% of all airborne particles reside. Typically, these particles are produced from everyday activity such as automobiles, factories, and even utilities and we recognize the pollutants as dust, dirt, soot, and smoke. Even forest fires and wood-burning stoves contribute high levels of these sub-micron particles.

They are also the most dangerous size particles as those under 1-micron in size can go deep into the lungs and enter the alveoli where there can be direct exchange with the blood. Even the best HVAC grade filters can only remove up to 70% of these particles, but a HEPA will be 99.97% efficient.

HEPA filters do have a very dense media and can result in overloading the typical air distribution fan in an HVAC system so seeking application expertise is always a good idea.

Remember, that that the Centers for Disease Control and Prevention (CDC) and other professional engineering organizations recommend HEPA filters in hospitals, infection control clinics and other healthcare facilities to eliminate airborne pathogens, microbes, and other dangerous particles.

HEPA filters will become more popular as the EPA continues to publish more data on the prevalence and dangers of PM1.

Leading Air Filter Company Camfil Announces Free Quick Cost Comparison Tool for Commercial Industries

Clean Air Solution by Camfil USA. Leader in Air Filters for Commercial and Industrial applications.

The online calculator provides cost comparisons for different air filters

Stockholm, Sweden – June 18, 2017 – Camfil, a world leader in air filtration and clean air solutions, has created a free Quick Cost Comparison tool that gives commercial facility supervisors the opportunity to compare the installation, labor and waste disposal costs of different pleated panel air filters / pre-filters.

Leading Air Filter Company Camfil Announces Free Quick Cost Comparison Tool for Commercial Industries

“We wanted to provide prospective clients in commercial industries with a tool that showed them exactly what the savings would be if they chose premium air filters over standard air filters,” stated Kevin Wood, Camfil USA Vice President Sales & Marketing. “This is online tool is extremely user-friendly, and produces immediate results.”

As users advance through the tool, they enter their pleated panel filter (pre-filter) information such as the number of filter openings, filter cost, labor cost to change a filter, and disposal cost for a filter. The Quick Cost Comparison tool does the rest.

“Once a user enters the information that is requested on each page, the tool calculates and compares the total usage, waste and disposal costs of the three-month air filters, six-month air filters, nine-month Camfil 30/30 Dual 9 air filters, and 12-month Camfil 30/30 Dual 9 air filters at a facility,” added Kevin Wood. “Although this is an estimated number, it is designed to very closely project what a commercial facility can expect to pay when using Camfil’s 5-Star filters versus the traditional three- and six-month air filters.”

The tool was developed to provide actionable information about how Camfil’s longer lasting air filters can result in significant savings, just in lower transaction costs and less storage alone. Energy savings; however, is not included in the Quick Cost Comparison calculation which is the biggest savings opportunity facilities can benefit from when they convert to Camfil’s 30/30 products. The heating, ventilation and air conditioning (HVAC) system within a commercial facility is a significant source of energy expenditure. Efficient air filters can reduce energy costs and help boost a company’s bottom line, while also improving indoor air quality.

Anyone interested in test-driving the Quick Cost Comparison tool can visit https://catalog.camfil.us/quick_cost.html. The tool provides data on-the-spot so facilities can understand how longer-lasting, high-performance pre-filters will result in substantial, on-going savings.

For a complete “Total Cost of Ownership” comparison, Camfil also offers the Life Cycle Cost (LCC) Analysis which is a modeling tool that takes into account all associated filter costs including energy.

How Data Center Pollution is Driven By Fossil Fuels, Backup Generators and Insane Network Demand

Clean Air Solution by Camfil USA. Leader in Air Filters for Commercial and Industrial applications.

Learn about the environmental challenges facing data centers.

As demands for network bandwidth continues to increase due to billions of online users, data center pollution has become a growing environmental concern. Although most people don’t really know where the power to stream movies or download videos comes from, the public does become aware of data centers when network grids overload and lead to a brownout.

“Data centers are springing up in every community to meet the growing network demands of consumers,” stated Kevin Wood, Camfil USA Vice President Sales & Marketing. “But with that demand also comes a number of environmental concerns, especially pollution created by power generators that run off fossil fuels including coal, gas and oil. It is an issue that can quickly become a health-care crisis if large companies can’t find solutions to mitigate the environmental damage caused by these facilities.”

Recent Data Center Statistics

As online activity has mushroomed to nearly unmanageable proportions, data centers have become the beating digital pulse that sustains networks throughout the world.

A piece on the Ciena website, (1) shed some light on the proliferation of data centers, citing statistics that show there are more than 7,500 data centers in the world, with a third of them located in 20 of the biggest cities on earth.

Furthermore, data center construction is expected to increase by 21 percent through 2018, as demand for networks continues to grow.

In the U.S., California leads all states with more than 300 data centers, second in the world only to London, which has 337 data centers.

But the growth of data centers does not come without an environmental cost.

Data centers require power to operate, which means the construction of new power plants to keep these facilities running.

The National Resources Defense Council warns that,(2) “data center electricity consumption is projected to increase to roughly 140 billion kilowatt-hours annually by 2020, the equivalent annual output of 50 power plants, costing American businesses $13 billion annually in electricity bills and emitting nearly 100 million metric tons of carbon pollution per year.”

In fact, more than 40 percent of the entire operating costs of a data center are spent on the power needed to keep these facilities running. This includes the costs of cooling the equipment to prevent malfunctions.

Data Center Pollution

People who binge-watch their favorite streaming TV series are not often aware that the power to keep that streaming channel running has an environmental cost.

Per The Guardian, (3) data centers throughout the world are contributing two percent of total global greenhouse gas emissions, which is nearly equivalent to the emissions from aircraft.

One example may help you understand how consuming content has a direct effect on the power necessary to keep that content streaming: Watching a 10-minute video of cute cats doing cute things on YouTube releases one gram of carbon dioxide into the atmosphere.

One of the lesser-known aspects about powering data centers is that many of the largest companies building the largest data centers fail to report fossil fuel usage in their emissions.

Per the Environmental Leader, (4) data centers such as those used by Google and Amazon, “underestimate fossil fuel usage by 30 percent or more, and thus have much higher emissions than they report.”

Lux Research estimated that Google’s massive data center in Berkeley County, South Carolina derives 62 percent of its power from fossil fuels, although the company reports fossil fuel usage at 35 percent.

Similarly, Amazon reports that its 23 data centers in Virginia only derive 35 percent of their power from fossil fuels, but Lux Research estimated that usage to be closer to 43 percent.

Why is this so important?

Because according to the Union of Concerned Scientists, (5) “coal plants are the nation’s top source of carbon dioxide emissions, the primary cause of global warming. In 2011, utility coal plants in the United States emitted a total of 1.7 billion tons of CO2. A typical coal plant generates 3.5 million tons of CO2 per year.”

Furthermore, fossil fuel burning is also a primary component of smog and pollution, and releases harmful pollutants such as sulfur dioxide, nitrogen dioxide, particulate matter (PM), and mercury.

Mindful of the public relations nightmare associated with using fossil fuels, some of the bigger companies such as Google are starting to invest heavily in clean, renewable energy, which provides some hope for the future as data center construction continues to grow.

Clean Air Solutions

Camfil understands the need to reduce data center air filtration , and knows the special requirements of data centers, including the proper cooling environment, and facilities where pollutants need to be controlled. We can help data center operators reduce their energy costs by as much as 40 percent by providing air filters that are efficient.

Could Lowering Outdoor Airport Pollution Help Improve Indoor Air Quality?

Clean Air Solution by Camfil USA. Leader in Air Filters for Commercial and Industrial applications.

Learn about how an airport in Minnesota is trying to tackle air quality

Airports are one of the most congested areas in major cities, because they are often located in places with high vehicle traffic and industrial processes. As a result, airport pollution has become one of the persistent problems for city officials, as they grapple with the long-term effects of bad air. There is hope, however, as some airports are taking the initiative to push through measures to lower pollution.

“There is really no optimum way to lower the amount of indoor pollutants at airports without first addressing how to reduce outdoor pollution at these places,” stated Kevin Wood, Camfil USA Vice President Sales & Marketing. “That is why you are seeing more initiatives at major airports aimed at lowering the amount of airborne pollutants. This may be a key aspect of improving indoor air quality.”

Sobering Airport Pollution Statistics

Vehicle exhaust and factory emissions are among the most common causes of airport pollution in major urban areas.

And far from being just a nuisance, airport pollution has become a real health care issue throughout the world.

Fine particulate matter and ozone emissions from civil aircraft are responsible for around 16,000 premature deaths annually across the world, according to a study carried out by researchers at the Massachusetts Institute of Technology (MIT) in the US. (1)

“We found that unregulated emissions from [planes flying] above 3,000 feet were responsible for most of the deaths,” stated Professor Steven Barrett, the author of the study and an aeronautical engineer at the Massachusetts Institute of Technology in Cambridge. “Regulators need to explicitly consider the impact of cruise emissions on human health.”

The challenge is that many of the pollutants generated at airports are particulate matter (PM) that is microscopic in size, much smaller than a strand of human hair and capable of being inhaled or swallowed.

Once inside the bloodstream, PM can burrow deep into the lungs and cause a number of respiratory problems.

The study also found that worldwide, an estimated 8,000 fatalities each year are caused by pollution generated by planes at cruising altitude, which is typically 35,000 feet.

Researchers had previously thought that the most dangerous emissions from aircraft occurred at takeoff and during landings, but this new study contradicts that belief.

But despite the challenge of airport pollution, researchers are convinced that the problem is manageable.

For example, sulfur is a significant component of jet fuel and has a damaging effect on human beings, but according to Barrett, it would cost only five cents a gallon in the U.S. to remove most of the sulfur in jet fuel.

Minnesota Airport Takes Steps to Reduce Airport Pollution

Officials who operate the Minneapolis-St. Paul International Airport are trying to do their part to lower air pollution.

Per a report by MPR News, the airport implemented new procedures two years ago, which requires airplanes to remain at cruising altitude for a longer period of time, rather than just approaching the airport.

According to Metropolitan Airports Commission Executive Director and CEO Brian Ryks, the new procedures are having a positive effect. (2)

“By keeping the aircraft throttle pulled back, they burn less fuel,” Ryks stated. “And consequently, [they] emit less carbon dioxide exhaust than they would using a traditional, staged descent to the runway.”

The new procedures have resulted in planes burning three million fewer gallons of fuel per year, and airport officials estimate that thousands of metric tons of carbon dioxide would be reduced in the airport area and adjacent communities affected by airport pollution.

This is significant, because a recent study has found that airport pollution has a wider impact than previously thought.

The Minnesota Post published a study that found that, (3) “a significant fraction of urban dwellers living near airports likely receive most of their outdoor [particle matter] exposure from airports rather than roadway traffic.”

Much of those pollutants are composed of sulfur dioxide and nitrogen dioxide that is released through jet exhaust vapors. These pollutants have been linked to serious ailments such as asthma and chronic obstructive pulmonary disease (COPD).

Another study found that children who lived near Logan International Airport in Boston were, “four times more likely to exhibit signs of undiagnosed asthma than children living in communities further away, even after taking into account socioeconomic and other factors.”

This all points to the importance of reducing airport pollution levels in order to improve health conditions for those working at the airports, and for residents in nearby neighborhoods.

How Premium Air Filters Can Save Your Company Money

Clean Air Solution by Camfil USA. Leader in Air Filters for Commercial and Industrial applications.

Learn about the value of installing effective air filters

As outside air pollution continues to worsen, it has a direct, negative effect on indoor air quality (IAQ). In fact, some studies have found that indoor pollution may be twice as bad as the pollution outdoors, which is why it’s so important for commercial facilities to install premium air filters. But instead of just improving the air quality, air filters can also save money through a reduction in energy costs.

How Premium Air Filters Can Save Your Company Money 1

“Well, we’ve discovered that there is really no substitute for good air filters at commercial facilities,” stated Kevin Wood, Camfil USA Vice President Sales & Marketing. “It is one of the areas that many business owners neglect, but when you talk about the elimination of pollutants, and the fact that premium air filters can improve the efficiency of the entire HVAC system, there is a real cost savings that can be achieved.”

A typical office building in the U.S. will spend an estimated annual average of $1.34 per square foot on power, according to National Grid, a major supplier of electricity in the US. (1)

Although energy consumption varies slightly based on climate zone, many office buildings consume the bulk of their energy through lighting, heating, office equipment, cooling and ventilation.

That is why so many commercial buildings can save money by installing high-efficiency HVAC units, which consists of efficient air-conditioning and heating units that are capable of lowering energy use by 10 percent or more.

In addition, commercial buildings can also implement what is known as demand-controlled ventilation, in which ventilation is significantly decreased when buildings are not occupied.

Demand-controlled ventilation is a smart system that can analyze the carbon dioxide (CO2) in the air flow and use that to determine how many people are in the building.

As the CO2 levels decrease, this indicates that the number of occupants is also decreasing, and the demand-controlled ventilation system automatically lowers the air supply accordingly.

Demand-controlled ventilation is most effective in commercial facilities in which occupancy rates vary, such as auditoriums, conference rooms and offices.

Savings through Air Filters

When managers of commercial facilities consider areas where they can cut costs to save money, they rarely look at the energy savings that can be achieved from installing quality air filters.

Because air filters are hidden from sight, it’s difficult to remember that they can be a source of energy savings.

But consider that in many commercial buildings, at least half the energy costs are related to the HVAC system. Moreover, an estimated 30 percent of those costs are related to air filters.

That means that anything you can do to improve the efficiency of that system will turn into actual savings.

And one of the more important aspects of air filters is how hard they force your HVAC system to work, and how efficiently they trap pollutants.

Air filters are designed to eliminate as many airborne particulates as possible, while also allowing the unimpeded flow of air to circulate through air vents.

The truth is that if you select a cheap air filter, you are doing your company a disservice, because these filters quickly accumulate dust and particles, forcing your HVAC system to utilize more power to force air through the clogged filters.

That means your HVAC system has to generate more power when your air filters are clogged, and lower-cost air filters are far more likely to become clogged in a short period of time.

Camfil’s Clean Air Solutions

Camfil HVAC air filters are made to capture pollutants and ensure optimum airflow for two to three times longer than regular air filters.

This means that you will not need to change your air filters as often, which lowers installation costs, reduces the amount of energy required to force air through your vents and saves you money.

Camfil air filters are designed for what is known as “lower average lifetime resistance,” (2) which means that your HVAC unit will not have to work as hard to allow air to circulate through the system, as it would have with a lower-quality filter. And while it’s true that Camfil air filters are more expensive than regular filters, it is important to understand that over the long-term, this higher expense will more than pay itself off as you trim your energy costs.This is known as total cost of ownership, and it takes into account factors such as installation costs each time you change the air filters, and the costs of buying new filters. Camfil filters are estimated to save you as much as 30 percent of total electric energy spend.

How Ventilation Affects Air Quality At Food Processing Plants

Clean Air Solution by Camfil USA. Leader in Air Filters for Commercial and Industrial applications.

Learn about air handling at food processing plants

Studies have found that even the most efficient air-conditioning system can spew out high amounts of bacteria into an indoor facility, and when that facility is responsible for the manufacturing and packaging of food, that pollutant can create a health crisis. That’s why air quality at a food processing plant is so important, and also why it’s nearly impossible to eliminate pollutants without an effective air filtration system. Also read our previous blog post.

Best Air Filters for Food Industry

“Outdoor air can carry from 200 to 1,500 bacteria per cubic meter,” stated Mark Davidson, Camfil USA Food & Beverage Segment Manager. “That means that poorly filtered air conditioning systems can circulate as much as 15 million bacteria each hour, and that can compromise the quality of products at food processing plants. Understanding the importance of temperature, humidity and air filtration are the keys to establishing an effective air filtration strategy.”

Like cleanrooms and bio-labs where sterility is required, food-processing plants must be kept as free of pollutants as possible. Per an article on food safety, one of the most common ways that pathogens enter these facilities is through air that flows from doors and other openings.

These pollutants are known as “bioaerosols,” defined as (1) “airborne contaminants that include bacteria, fungi, viruses and pollen. These free-floating microorganisms may be present in the air as solids (dust) or as liquids (condensation and water), and they are an important bacterial vehicle.”

The problem is that there are often deficiencies and breakages within those openings that allow pollutants to enter the food processing facility.

That’s why the proper sealing of doorways and openings is one of the key factors in preventing pathogens from flowing through the facility.

Per the article, there are other issues in addition to sealing openings:

“Slow operating doors compromise quality and safety by enabling dust and fumes to travel with the forklift between areas. Slow speed can also reduce control over desired temperatures, threatening food quality. The faster a door operates, the more effective it serves as a barrier.”

The Importance of Air Flow

One of the biggest problems in a food processing facility is the constant amount of negative pressure.

That is the reason that food processing facilities must have as many as two-dozen air changes per hour.

Years ago, the U.S. Department of Agriculture had established a minimum of six air changes per hour for meat packing facilities, but that requirement was phased out. Typically, food-processing facilities need about 20 to 25 ACHs per hour to: (2)

“…remove off odors, steam and other airborne contaminants and filter them out of in the recycle process. The actual number of air turns depends on the type of processing taking place in the plant and must be designed by a competent HVAC engineer to fit the facility and the process.”

“Airflow in meat-processing plants, due to the presence of live animals, carry a high risk of airborne contaminants.”

In a piece on the Stellar Food for Thought website, design and construction expert Luke Facemyer writes: (3)

“In these facilities, the direction and frequency that air flows is especially important. The air from kill floors and rendering areas, where raw poultry and meat are handled, must never flow to areas such as packaging, where the airborne bacteria could infect the final product.”

Facemyer also writes that condensation control and temperature control must be strictly regulated to ensure the proper air balance between different areas or rooms of a food processing facility.

Condensation in particular can create moisture in “equipment crevices and on ledges,” causing the growth of bacteria and mold.

Hospital Air Quality Matters – Learn Data from Camfil Report

Clean Air Solution by Camfil USA. Leader in Air Filters for Commercial and Industrial applications.

Learn the challenges hospitals face in improving air quality

As a place of healing and recovery, hospital air quality is even more important than the air quality at commercial offices and shopping malls. The purpose of a hospital is to return people to good health, and an essential aspect of this process is ensuring that airborne pollutants do not make existing conditions worse.

“Well we know from our research that many hospitals are struggling with their budgets,” stated Dave Blackwell , Healthcare Business Segment Manager . “As a result, these facilities are installing low-cost air filters that are not providing the kind of return-on-investment that is ideal, and worse yet, these filters are not eliminating the kind of pollutants that are a clear and present danger to patients and hospital workers. This issue was serious enough that ASHRAE Standard 52.2 was recently amended to require manufacturers to test all MERV rated air filters, including hospital air filters. Simply put, hospitals should demand ASHRAE test reports be supplied by their supplier.

Main Challenges to Hospital Air Quality

The biggest reason that hospitals are forced to spend more on air quality is that these facilities face greater pollutant challenges than other enclosed spaces.

Per an article on the Consulting-Specifying Engineer website, (1) patients and hospital workers are two significant factors in hospital air quality.

Because hospitals are filled with patients who have a variety of ailments, there is a much higher likelihood that some of these patients can release infectious contaminants that can impact indoor air quality.

For example, per an article in Healthline, (2) a recent study by researchers at Massachusetts Institute of Technology that was published in the Journal of Fluid Mechanics found that coughs and sneezes can travel 200 times further than what scientists had thought.

Most scientists agreed that the cloud of infectious pollutants in a cough could travel 200 feet, but the new study found that “droplets 100 micrometers in diameter can travel five times farther than previously estimated, that droplets 10 micrometers in diameter can travel 200 times farther, and that droplets less than 50 micrometers in size can remain airborne long enough to reach ceiling ventilation units.”

The study was important in terms of understanding how airborne pollutants within a hospital can compromise air quality and lead to infectious outbreaks.

Lydia Bourouiba, the author of the study and an Assistant Professor at MIT’s Department of Civil and Environmental Engineering stated:

“This can all help target and improve mitigations strategies such as spacing between patients in hospitals, air ventilation and filtration in confined spaces.”

But for medical officials to implement an effective air filtration strategy, they must have sufficient resources, which more often than not, is all about money.

Budgeting Effects on Hospital Air Quality

There’s been a lot of news lately about the number of public hospitals that are facing extreme state budget cuts and changes in how Medicaid reimburses them for treating patients.

And while this may seem tangential to hospital air quality, it drives at the heart of the funding crises that has forced many health care officials to use lower-cost air filters that do not have the capacity to eliminate the most harmful particulates that can affect patient and worker health.

In addition, many hospitals are burdened by the amount of money they have to spend on patients who are admitted with respiratory illnesses directly tied to air pollution.

But a recent study published on the Rand Corporation website (3) has found that insurance companies such as Medicare and hospitals could actually reduce their spending on acute care if they focused on reducing the overall level of air pollution.

The study tracked the number of pollution related hospital events at five California hospitals from 2005 to 2007, and determined that both hospitals and health care insurers would have saved significant money on caring for patients with pollution-related ailments if they had helped the state meet federal clean air standards.

Per the article:

“Meeting federal clean air standards would have prevented an estimated 29,808 hospital admissions and ER visits throughout California…Nearly three-quarters of the potentially prevented events are attributable to reductions in ambient levels of fine particulate matter, that is, particulate matter with an aerodynamic diameter of less than or equal to 2.5 micrometers [PM 2.5].”

Translated into raw numbers, the failure to meet clean air standards cost health care insurers $193,100,184 during the two-year time-period of the study.

That means that improved air quality would have eliminated nearly $194 million in health care spending, not just for insurers, but also for the hospitals that were burdened with patients in need of acute care for these pollution-related illnesses.

And while this is just one study on the problem, it’s clear that any push to reduce outdoor pollution will have a positive net effect on indoor air quality at many hospitals, thereby reducing expenses and helping to focus more resources on air filtration.

And speaking of saving money………Energy efficient, long –life air filters can reduce energy spend for your hospital’s HVAC system and cut installation labor costs by 2-3 times. Most hospitals don’t realize that high quality air filters can save more than they cost.
