3 Types of Indoor Air Pollutants Your Home Air Filter Should Be Able to Remove


Your home’s indoor air quality can have an important impact on your family’s health. Your home’s air filter plays an important role in ensuring that you and your family breathe clean air. Here are the 3 types of air pollutants that your air filter should be able to remove:


1.   Particle Pollutants

Particle pollution is one of the air pollutants that your home air filter should be able to remove. Particle pollution, also known as particulate matter (PM), is made up of tiny pieces of liquids, solids or a mixture of both that are in the air.


Particles differ in sizes; some particles are big enough for you to see, while some are too small. The bigger particles are called PM10 – referring to particles 10 micrometers in width or more than 2.5 micrometers. Dust is an example of a bigger particle.


The smaller particles, meanwhile, are called PM2.5 as they’re less than 2.5 micrometers in width. Examples of smaller particles are pollen, dust mites and soot (produced when materials are burned).


According to the Centers for Disease Control and Prevention (CDC), breathing in bigger particles can irritate your nose, eyes and throat. The CDC said breathing in smaller particles are more dangerous as they can enter into the deep parts of your lungs or even into your blood.


CDC said people who are most likely to experience health effects as a result of particle pollution include those with heart or lung diseases (for example, asthma), older adults, babies and children.


2.   Bioaerosol Pollutants

Bioaerosol is a subcategory of particle pollution that refers to any airborne particles that are biological in origin. Bioaerosols vary in sizes. Based on their sizes, they can either be a bigger particle or a smaller particle. 


Animals, plants, soil and water are potential sources of bioaerosols. Given that these biological sources are present in nature, this means that bioaerosols are present in just about everywhere. Mold is an example of a bioaerosol.


According to Health Canada(PDF), molds are of special interest in terms of human health as some molds contain inflammatory properties, others contain allergens, and some have toxic properties. Major causes of mold growth, according to Health Canada, are condensation of moisture on surfaces as a result of excessive humidity, lack of ventilation, water leakage (from a broken pipe), and water seepage from the outside (from a leaking roof, cracked basement or flood).


Health Canada and the Institut national de santé publique du Québec published reviews of the scientific literature relating to the health effects of molds on human health. The organizations concluded that exposure to indoor mold increases the prevalence of asthma-related symptoms, including chronic wheezing, irritation symptoms and non-specific symptoms.


3.   Odor/Chemical Pollutants

Odors can be both pleasant and unpleasant. Some odors can be health hazards and some aren’t.


Harmful odors can come from volatile organic compounds (VOCs), harmful chemical contaminants found in many home environments. Examples of harmful odors derived from VOCs are paints, wall coverings, cleaning agents, carpeting, vinyl flooring, fabric materials and furnishings, air fresheners, perfume and shampoos.


“If these VOCs and other chemical contaminant sources are not controlled, indoor environmental quality problems can arise, even if the building’s ventilation system is properly designed and well maintained,” the CDC said.


Formaldehyde is another example of a harmful odor. At room temperature, formaldehyde has a pungent, suffocating odor. Formaldehyde is used as a food preservative. It’s also used in household products, including antiseptics and cosmetics.


“Exposure to formaldehyde can irritate the skin, throat, lungs, and eyes,” the CDCsaid. “Repeated exposure to formaldehyde can possibly lead to cancer.”


Lennox Healthy Climate HEPA Filtration System

The Lennox Healthy Climate HEPA air filter eliminates particle pollution, bioaerosols and harmful odors through its 3-step air filtration process. This air filter uses the same filtration technology used in hospital operating rooms and science labs. It functions like a vacuum; it pulls dirty air and then undergoes a 3-step cleaning process.


Stage 1 of the Filtration Process

The first stage of the Lennox Healthy Climate HEPA filtration process is called “Pre-Filter”. In this stage, bigger particles – those particles that are more than 2.5 micrometers in width – are removed from the air.


Stage 2 of the Filtration Process

The second stage of the air filtration process is called “HEPA”, which stands for high-efficiency particulate air. In this stage, smaller particles – those particles that are 0.3 micrometers in width and less than 2.5 micrometers – are removed from the air. At this stage, 99.97% of particulates, including bioaerosols, are removed from the air.  


Stage 3 of the Filtration Process

The third stage of the Lennox Healthy Climate HEPA filtration process is called “Carbon”. The word “Carbon” refers to the 1/2-inch thick carbon filter used for removing odors and chemicals from the air. This air filter comes with an optional carbon canister that removes more odors and toxins like formaldehyde. After this last filtration stage, the clean air is then released from the air filter to be introduced into the air you and your family breathe.


Keeping your home free from air pollutants is important as according to Health Canada, Canadians spend approximately 90% of their time indoors. Installing Lennox Healthy Climate HEPA air filter in your home ensures that 99.97% of particle and bioaerosol pollutants, as well as harmful odors, are removed several times a day.


Health Canada recommends that your home air filter should be used along with good ventilation and reducing and eliminating sources of indoor air pollutants. Call ustoday to improve your air quality and protect your family.
