A unit of measurement equal to one millionth of a meter, or 1/25,000 of an inch. Airborne particles – such as dust, dander, mold and viruses – are measured in microns. These tiny particles can circulate in your home’s air and have harmful effects on your family’s health and comfort.

What’s in my home’s air?

The short answer: a lot. Indoor air pollutant levels can be up to 100 times higher than outdoor levels.* Airborne pollutants include anything from dust, pollen and pet dander to bacteria, mold and chemical vapors. Larger particles, such as pollen, may be as big as 100 microns (1/125 of an inch) in diameter, while airborne viruses may measure only 0.01 micron in size.

Left unfiltered, these tiny particles can lead to health problems such as allergies, asthma and other respiratory illnesses. They can also cause damage to furniture, flooring and create unpleasant odors in your home. 

The most effective home air filtration systems

To ensure you’re breathing the healthiest air possible, look for whole-home filtration systems that can effectively remove invisible pollutants such as bacteria and mold. The Healthy Climate® HEPA bypass filtration system is 99.97% efficient at removing particles and bioaerosols down to 0.3 micron in size. The PureAir™ Air Purification System from Lennox takes it even further, filtering out 90% of germs and bacteria down to 0.01 micron.**
