Most people understand how harmful outdoor air pollution like car emissions can be, but they don’t realize that the air inside the average house might be more polluted—depending on actual conditions, it can be up to five times more. Things have become so dangerous, the EPA has indoor air pollution ranked as a top five environmental danger. Mold, pollen, pet dander, radon and even formaldehyde are commonly found in homes. Since Americans spend around 90% of their time indoors, good indoor air quality is crucial for decent health, regardless if it’s in our homes or our workplaces. To help contain this pollution and better our indoor air quality, we can take different measures. But first, we are required to grasp some vernacular consistently used to discuss indoor air quality.
HEPA is a term a lot of people have heard or seen, but did you know it stands for “high-efficiency particulate air” or “high-efficiency particulate arrestance”? HEPA filtration systems are engineered—and certified—to capture at least 99.97% of .3-micron particles (tinier than the diameter of a human hair) from the air that filters through the system. This significantly increases your home’s indoor air quality when dust, pollen, mites and other contaminants are captured.
Minimum efficiency reporting value or MERV describes the effectiveness of an air filter. With ratings ranging from 1–16, you should find a higher rating that specifies the filter will remove more contaminants and allergens from your air without restricting the airflow of your home comfort system. Ask us which MERV-rated filter will work best for your home.
