How Air Pollutants Absorbed by Industrial Air Filters Are Threatening Plants and Animals

The air pollutants that industrial air filters remove from the air can harm the health of animals and plants as well as the health of humans.

When most people think about damage from air pollution, they think of it in terms of its effects on human health. This is understandable, as we’re humans and we filter what we know about the world through our own experiences. Yet it’s important to remember that air pollution negatively affects the entire world around us, which includes plant life and animal life as well.

Animals and plants are damaged by many of the same pollutants that damage human health, and since our ecosystem includes the plants and animals around us, it’s important to look at pollution reduction across the spectrum. After all, reducing the amount of air pollution in the environment doesn’t just benefit us by shielding our lungs from air pollution, it also benefits the animals and plants in our environment, which play a vital role in how we live our daily lives.

Commercial HVAC Air Filters Absorb Toxic Pollutants That Can Harm the Environment

Air pollutants can damage the leaves and roots of plants, and harm animal lungs in much the same manner that they harm human lungs. These pollutants come from a variety of sources: some are natural and some are man-made. It’s important to note, however, that man-made sources are the primary way most air pollutants get into the air.

The air pollutants released by human activity include:

Chlorofluorocarbons that are released by refrigerants, solvents, and propellants. They wear away at the stratospheric ozone layer, which protects the surface of the Earth from the sun’s ultraviolet radiation.
Nitrogen oxides and sulfur dioxide that come primarily from the combustion of fossil fuels at industrial facilities, power plants, and by motor vehicles. The pollutants contribute to the acidification of water droplets in the air, which causes acid rain.
Volatile organic compounds have a variety of human sources, and they are capable of interacting with heat and the chemical energy from the sun to create ground-level ozone.
Particulate matter is an umbrella term for any small particles of air pollution capable of doing damage to people’s health. Particulate matter is divided into different categories like PM1, PM2.5, and PM10 (these particles are smaller than 1-micron in size, smaller than 2.5-microns in size, and smaller than 10-microns in size respectively).

Commercial HVAC air filters are capable of removing most of these pollutants, but animals living outdoors can’t take advantage of their protective capabilities.

Commercial Air Filtration Systems Prevent The Damaging Health Effects Of Air Pollution

The various air pollutants released by human activity can harm plants and animals in a number of different ways. Acid rain and ozone can harm plants, while particulate matter can damage the lungs of animals. A weaker ozone layer can harm almost all life on the planet.

“The degradation of the ozone layer caused by chlorofluorocarbons means that more ultraviolet radiation hits the surface of the planet, damaging the leaves of plants and harming the skin of animals,” stated Camfil’s Charlie Seyffer, Manager of Marketing & Technical Materials and 37-year ASHRAE member and active committee participant.

Unlike when ozone is in the upper atmosphere, tropospheric ozone is a harmful air pollutant that damages the lung tissue of animals and prevents plants from being able to respire. Since plants can’t respire when in clouds of ozone they can’t photosynthesize as efficiently, meaning they’re unable to grow.

In terms of how air pollution harms the lungs of animals, the lungs of other mammals tend to be similar in construction to the lungs of humans. Particulate matter and ozone air pollution can degrade the cells of the lungs, impacting their ability to supply the body with the oxygen it needs. Ozone and particulate matter can permanently decrease lung function if exposure to the air pollutants is at a high level or exposure continues over a long period of time. The two pollutants can lead to the development or exacerbation of asthma in humans, and to similar respiratory diseases in other animals.

Particulate matter can penetrate into the lungs and bloodstream of humans and other animals, doing substantial damage to the lungs and heart. In humans, exposure to particulate matter can cause stroke, brain damage, ischemic heart disease, and other cardiovascular or respiratory ailments. Particulate matter can also damage the body of animals in other ways.

“There is some evidence that other animals can develop similar ailments to humans,” explains Seyffer. “Studies examining dogs from the heavily polluted regions of Mexico City found that the animals displayed forms of neurodegeneration similar to Alzheimer’s disease, not unlike the implications for humans who are continually exposed to air pollution as well.” (2)

The Pollutants Neutralized by Industrial Air Filtration and Ventilation Can Harm Entire Ecosystems

Air pollutants can harm animals and plants in ways other than direct exposure. This is because air pollution can damage ecosystems and lead to global warming.

Acid rain is one-way air pollution can damage an entire ecosystem. It can easily destroy plant leaves, rendering the plants incapable of photosynthesis, which eventually causes them to die off. When the acidic water soaks into the ground it can also damage plant roots, and harm aquatic wildlife living in streams, ponds, and lakes.

Even if the damage caused by air pollution seems small, the die-off of a single species of fish in one pond, for example, can have ripple effects that harm many more animals and plants. Ecosystems depend on a delicate balance of interactions between different species. If one species dies off, it can destabilize an entire food web, leading to an ecosystem collapse.

“Species that play critical roles within an ecosystem are referred to as keystone species because the loss of them makes the entire arch (ecosystem) collapse,” expanded Seyffer. “If a keystone species were to be damaged or wiped out by severe air pollution, the rest of the ecosystem would suffer greatly. If an insect cannot breed due to the acidification of the water it normally breeds in, the frogs that feed on it will have less food and can die off themselves.” (3)

Certain kinds of air pollution, like methane and carbon dioxide, also lead to global climate change. Global climate change can cause certain areas of the globe to warm and other areas to cool. The hotter climate is causing desertification of fragile ecosystems, the gradual elimination of vegetation and other forms of life from an area. Global climate change is also causing sea level rise due to the melting of the polar ice caps, causing many biomes and ecosystems near the shore to be flooded and swept out to sea.

Commercial HEPA Air Purifiers Are a Way to Protect Ourselves and Our Domestic Animals

The variety of air pollutants that can harm human and animal health can typically be captured with commercial HEPA air purifiers. HEPA stands for High-Efficiency Particulate Air, and it refers to the fact that the filters used in the purifier can absorb most of the dangerous air pollutants exposed in a home. While wild animals can’t benefit from these devices, domestic house pets and humans can, so it remains vital to use them to defend against damaging air pollutants.

When making purchasing decisions about commercial HEPA air purifiers, look for air purifiers that use replaceable HEPA filters. HEPA filters are capable of absorbing up to 99.97% of all particles of pollution as small as 0.3-microns in size. If you live in a particularly polluted area, you may wish to employ a HEPA air purifier to protect the health of your pet, as well as your own health.

Ecosystems Require Protection Beyond Air Filtration Units

It’s critical to think beyond air filtration units and to develop and sustain pollution control methods that will reduce overall emissions of air pollutants. Pollution control strategies can include regulations by government bodies, investments in clean energy and travel technology, and education about ways to reduce individual emissions of pollutants.

Government bodies have the power to create regulations that will curb emissions. It’s important to place limits on smokestack emissions from industrial facilities, mandate motor vehicle mileage standards, and institute cap and trade programs to incentivize companies to reduce air pollution emissions.

Investing in technology that reduces emissions is another way to improve air quality. Emissions reduction technology includes electrostatic precipitators, smokestack scrubbers, and catalytic converters. Electric vehicles and associated infrastructure like charging stations can also reduce emissions.

“Educational programs can help citizens understand the role they can play in curbing emissions and managing their carbon footprint,” claimed Seyffer. “Educational programs can address how citizens can carpool, use public transportation, use energy efficient appliances, make use of environmentally-friendly cleaners, and lower their energy consumption to prevent air pollution.” (4)

Air pollution leads to shorter, unhappier, tougher lives for both animals and humans alike. It’s important to reduce our air pollution emissions where possible and to use commercial or industrial air filters to protect the health of our families and our pets.

Four Problems The EPA Faces In Reducing Pollutants Removed by Commercial Air Filters

Air pollution has the potential to harm people’s health and welfare in a variety of different ways, making programs to control air pollution of vital importance. Since the 1970s, the Environmental Protection Agency (EPA) has been tackling various problems regarding air pollution, largely through the landmark Clean Air Act, an effort that has substantially reduced levels of different air pollutants and made the air safer for everyone.

Yet despite these improvements to air quality in the United States, the EPA and other regulatory bodies still grapple with various challenges in cleaning up the air. An abundance of common air pollutants, toxic airborne compounds, a damaged stratospheric ozone layer, and climate change are all issues the EPA is attempting to solve.

What kind of progress is being made in the attempts to solve these issues? What strategies are working to address these challenges?

High Efficiency Air Filtration Units Trap The Criteria Air Pollutants

One of the primary purposes of the Clean Air Act is to control six different air pollutants referred to as the “criteria air pollutants” by the EPA. These “criteria air pollutants” – carbon monoxide, lead, nitrogen oxide, sulfur dioxide, ground-level ozone, and particulate matter – pose the greatest threat to human health by virtue of their toxicity and ubiquity. Industrial air filtration units can capture most of these air pollutants, but not carbon monoxide.

Carbon monoxide air pollution has basically been driven down to acceptable levels nationwide according to the air quality standards set by the EPA. This is a substantial triumph as carbon monoxide exposure can quickly lead to brain damage, lung damage, and death. Special gas phase filters must be used to capture carbon monoxide, meaning that traditional air filters are ineffective against the toxic compound.

Levels of atmospheric lead have been greatly reduced by the Clean Air Act, which is responsible for phasing out lead in gasoline for motor vehicles. This is an excellent achievement as exposure to lead can lead to neurological issues, like behavioral issues and difficulty learning, especially in children. Levels of atmospheric lead are now only beyond the air quality standard near specific industrial facilities that emit large levels of lead.

“In terms of nitrogen oxide and sulfur dioxide pollution, the EPA will be working alongside state and city governments to isolate major sources of the two air pollutants,” educated Camfil’s Charlie Seyffer, Manager of Marketing & Technical Materials and 37-year ASHRAE member and active committee participant. “Common sources of sulfur dioxide and nitrogen oxides are industrial facilities and power plants. A substantial amount of nitrogen oxide is also released by the combustion of gasoline for cars. Exposure to both nitrogen oxide and sulfur dioxide can lead to the exacerbation or possible development of asthma and respiratory infections. The two compounds also contribute to acid rain which causes environmental damage.” (1)

Ground level ozone is created when volatile organic compounds (VOCs) interact with chemical energy from the sun in the presence of heat. Ozone at ground level is a toxic air pollutant that can require hospitalizations when people are exposed to high concentrations. Ozone can also irritate the eyes, nose, and throat, cause difficulty breathing, and permanently decrease lung function.

Particulate matter refers to all fine particles of pollution smaller than 2.5-microns in size, or 50-times smaller than the width of a human hair. At this small size, it can penetrate into people’s lungs and bloodstream causing damage to the respiratory and cardiovascular system. Particulate matter exposure is correlated with things like stroke, heart attack, chronic obstructive pulmonary disease, asthma attacks and lung cancer.

The EPA has managed to substantially cut levels of both ozone and particulate matter of the past couple decades, but levels of these two air pollutants are still well beyond acceptable standards in many cities around the country.

Toxic Pollutants are Dangerous without Commercial Air Filtration Systems

Though not as ubiquitous as the criteria air pollutants, the EPA also tracks the intensity of many different toxic pollutants like benzenes, methylene chloride, cadmium, and mercury. In fact, the EPA tracks 187 pollutants that can cause respiratory damage, cardiovascular damage, cancer and other diseases.

These hazardous compounds can come from a variety of different sources such as solvents, paint strippers, dry cleaning facilities, building materials and chemical cleaners. The most prolific sources of airborne toxins are chemical manufacturing facilities, steel mills, power plants, and aerospace manufacturing facilities.

Levels of toxic air pollutants like benzenes are highest in urban areas, and the EPA estimates that about 14 million people who live in more than 60 urban centers across the country have lifetime cancer risks that are higher than 100 out of 1 million. This is compared with the regular risk of 10 in 1 million.

Standards created by the EPA have been highly successful in reducing overall levels of air pollution, and the concentration of benzenes in gasoline and other forms of fossil fuels has been substantially reduced. The EPA has also managed to get 174 major source categories to hit emissions standards, along with 68 categories of smaller sources.

Commercial HVAC Air Filters Can’t Reduce Levels of Atmospheric Carbon Dioxide

Aside from controlling the criteria for air pollutants, another challenge the EPA is dealing with is the threat of global climate change. Climate change is driven by greenhouse gases, which are gases that trap heat in the atmosphere and cause the globe to warm. This is called the “greenhouse effect,” and the EPA is attempting to control levels of greenhouse gases within the atmosphere.

The air pollutants that cause the greenhouse effect – carbon dioxide, nitrous oxide, methane and various fluorinated gases – are often trapped by commercial HVAC air filters. Unfortunately, however, while filters clean indoor air, they can’t address the larger problem of greenhouse gas emissions in the atmosphere.

“The vast majority of greenhouse gases within the atmosphere are released by human activities like the combustion of fossil fuels at industrial facilities, power plants and by automobiles,” explained Seyffer. “The effects of the global warming caused by the greenhouse gases are substantial and harmful to human health in a variety of ways. Global warming causes hotter summers, and some of these can lead to life-threatening heat waves. Global warming also leads to sea level rise that can devastate oceanside towns and communities.” (2)

The EPA has issued limits on emissions of greenhouse gases from cars, mandating the use of devices like catalytic converters and fuel economy standards. In addition, the EPA has also:

Started requiring that greenhouse gas emissions from refineries, power plants, and other industrial facilities be controlled through design choices that limit emissions.
Created the Clean Power Plan, which was established to advance the creation of alternative energy infrastructure like solar power plants, wind turbines, and hydroelectric dams. This is combined with strong standards for existing power plants and industrial facilities.

Avoid Air Purifiers That Generate Ozone

Another challenge that the EPA is tackling is the degradation of the ozone layer. The stratospheric ozone layer is what protects the earth from the sun’s ultraviolet rays. Compounds known as chlorofluorocarbons (CFCs), along with other compounds like trichlorofluoromethane, rise into the stratosphere where they degrade the ozone layer. This means that more ultraviolet radiation hits the surface of the planet, causing skin cancer, cataracts, and crop damage.

In order to preserve the ozone and prevent the harmful effects of ultraviolet radiation, countries around the world, including the U.S., have agreed to abide by a treaty known as the Montreal Protocol. The Montreal Protocol mandates the reduction of emissions of ozone-depleting compounds like CFCs.

These chemicals have been phased out by the U.S. in many ways, including transitioning to less damaging chemicals for use in refrigerants. The EPA has also established programs to label products containing ozone degrading substances and to properly recycle objects containing the substances. Some industrial air purifiers also generate ozone through their operation, so it is important to avoid using them.

Though substantial progress has been made in reducing emissions of ozone degrading chemicals, further steps to complete the phase-out of the chemicals must be taken. Since CFCs and other ozone degrading compounds hang around in the atmosphere for a long time, the EPA plans on helping the ozone layer recover by investing in technologies that further improve energy efficiency and reduce emissions of CFCs.

Air Filtration and Ventilation aren’t Enough to Protect People’s Health, Emissions Reduction Strategies are Needed

Though the Clean Air Act and other acts established by the EPA have managed to greatly reduce the amount of criteria air pollutants, ozone degrading compounds, and toxic pollutants in the air, there is still a lot more work to be done. The EPA advocates an eclectic air pollution management strategy that brings together science and engineering solutions, action from different levels of government, and public participation into a cohesive clean air management strategy.

“Science and engineering-based solutions include the development of clean energy technologies like renewable resources like solar power and wind power,” expanded Seyffer. “The creation of devices like catalytic converters, smokestack scrubbers, and low-VOC paints can also reduce the number of air pollutants emitted by industry operations.” (3)

It’s arguable that the biggest challenge currently facing the U.S. and the rest of the world is in reducing emissions of greenhouse gases. The United States recently chose to withdraw from the Paris Accord, a worldwide agreement to limit emissions of greenhouse gases. The Trump administration has reduced support for greenhouse gas regulations and alternative energy sources in a bid to increase investments in fossil fuels like shale gas. Due to the fact that the EPA under the Trump administration is dealing with possible budget cuts and less support for its renewable energy policies, many state and local governments have recently pledged to adhere to the tenets of the Paris Accord even if the federal government will not.

The federal government, state governments, and local governments all have their role to play in reducing emissions of greenhouse gases and other air pollutants. Managing emissions from motor vehicles and industry can be done at both the local level and federal level. State governments act as an intermediary between federal regulatory bodies and the city governments that will oversee the implementation of emissions reduction policies in their area.
