Health Reasons Why Your Home Needs a HEPA System Air Filter

If you’re particularly concerned about the air quality in your home, consider replacing your aging air filter with a HEPA System Air Filter.

An Air Filter is a device that removes airborne particles that if inhaled, are harmful to humans. Examples of airborne particles include dust, pollen, fungal spores, pet dander etc. A HEPA (High Efficiency Particulate Air) Air Filter removes almost all air pollutants. The Lennox Healthy Climate HEPA System Air Filter is an example of a HEPA System Air Filter that removes up to 99.97% of pollutants.

Particulate Matter

Particulate matter, also known as PM, refers to a range of particles found in the air that are less than 2.5 microns in diameter (the average size of a human hair is 60 microns). 

Particulate matter can be liquid, solid or a mixture of both. Anything that’s 2.5 microns in size or less is small enough to be carried by air and humans run the risk of breathing it into their lungs. You can’t see particulate matter – it can only be seen using a microscope.

The most common sources of indoor particulate matter are:

  • Pollen
  • Fungal spores
  • Endotoxin – a toxin found in bacteria
  • Tiny solid or liquid particles in aerosols
  • Carbon, also known as soot, produced when something is burned


Another example of particulate matter is mold. It refers to a range of fungus that grows on damp building materials or food. Sometimes molds can be observed in a variety of colors; in some cases, they can’t be seen, you’re only aware of it because of their musty odor. Having mold present in the home contributes to poor air quality.

Mold grows wherever there’s moisture. This moisture could be a result of water leaks, flooding, or high humidity from everyday activities like showering or cooking.

Adverse Health Effects of Mold

A study conducted by the Institute of Medicine (IOM) showed that there was sufficient evidence linking indoor exposure to mold with upper respiratory tract symptoms– wheezing and coughing in healthy people.

The IOM study also showed a correlation between indoor mold exposure and respiratory illness in healthy children.

Adverse Health Effects of Particulate Matter

According to the Centers for Disease Control and Prevention (CDC), breathing in matter that is larger than particulate matter, also known as coarse particles, can result in eye, nose and throat irritation. The CDC stated that breathing in particulate matter is more dangerous as it can get inside the deep parts of your lungs or even make its way into your blood.

While particulate matter can affect everyone, it can bother some people more than others. According to CDC, people with heart or lung diseases, older adults, babies and children will most likely experience health effects after exposure to particulate matter.

The CDC stated that particulate matter can worsen asthma symptoms. This pollution also has also been linked to the following health effects:

  • Eye irritation
  • Lung and throat irritation
  • Trouble breathing
  • Lung cancer
  • Problems with babies at birth (for example, low birth weight)

According to CDC, if you have a pre-existing heart disease, breathing in particulate matter can cause serious problems (such as a heart attack) with symptoms including:

  • Chest pain or tightness
  • Fast heartbeat
  • Feeling out of breath
  • Being more tired than usual

How to Reduce Exposure to Particulate Matter in Your Home

One of the ways to reduce exposure to particulate matter in your home is by using theLennox Healthy Climate HEPA System Air Filter. This particular air filter can be used independently or installed in forced air systems. Your indoor air goes through a 3-stage filtration process in the Healthy Climate HEPA System Air Filter, detailed as follows:

1stStage: Pre-Filter Stage

This filtration stage removes larger air pollutants like dust, pollen and pet dander.

2ndStage: HEPA Stage

This filtration stage removes up to 99.97% of particulates 0.3 micron and smaller.

3rdStage: Carbon Stage

This last filtration stage removes chemicals and odors from the air. The clean air is then released from your air filtration device and into the air you breathe.

The Lennox Healthy Climate HEPA System Air Filter should be used along with the steps below to reduce exposure to particulate matter in your home:

  1. Regular House Cleaning

Molds thrive in damp environments. Particulate matter like molds can be reduced by eliminating damp areas using a mop and other cleaning materials.

  1. Avoid smoking indoors and using candles and incense in your home. A study conducted by Health Canada in different Canadian cities showed that the average indoor particulate matter concentrations were less than 15 µg/m3 in homes without smokers, and less than 35 µg/m3 in homes with smokers.
  1. Move dusty work outside, for example, woodworking using power tools.
  1. Ensure your furnace is working properly and follow the manufacturer’s directions for maintenance.
  1. Install exhaust fans in the kitchen and in bathrooms. Make sure that these fans are properly installed and maintained.

“Everyone is exposed to air pollution. Air pollution, even at low levels, has an impact on human health,” the Government of Canadasaid. “Science has clearly shown that air pollution leads to disease, increased hospitalizations, and even premature death.”

Air pollution, the Government of Canada said, can be linked to nearly 14,400 premature deaths per year in Canada.

“As people spend a considerable amount of time indoors, either at work or at home, indoor air quality plays a significant part in their general state of health,” the World Health Organization (WHO)said. “This is particularly true for children, elderly people and other vulnerable groups.”
