Breathe Easy: The Positive Effects of Clean Air on Your Health and Well-Being

The EPA estimates that indoor air can be two to five times more polluted than outdoor air. We spend roughly 90 percent of our time inside, which means the air in our homes is the air we breathe most.

Allergens and respiratory health

Pollen, pet dander, mold spores, and dust mite waste are the most common indoor allergens. A high-quality pleated filter (MERV 10 or higher) traps the bulk of these particles before they recirculate. For allergy and asthma sufferers, the difference is often immediate.

Sleep and cognition

There's growing research linking poor indoor air quality to disturbed sleep and reduced cognitive performance. When your body is fighting irritants in the air all night, recovery takes a hit. Cleaner air at night = better sleep, plain and simple.

Long-term health

Exposure to fine particulate matter (PM2.5) is linked to a long list of long-term health issues — cardiovascular disease, reduced lung function, and more. MERV 13 filters capture a meaningful portion of PM2.5 and are the right call for households near busy roads, wildfire-prone areas, or anyone with respiratory sensitivities.

What to do about it

Replace your filter on time. Open windows when outdoor air quality is good. Vacuum with a HEPA-equipped vacuum. And if you have multiple HVAC return vents, make sure all of them have filters in good shape — one neglected filter can negate the work of the others.
