Most people are aware of how detrimental outdoor air pollution like car emissions can be, but they don’t realize that the air inside the typical house can be more polluted—contingent on actual situations, it can be up to five times more. Things have become so bad, the EPA has indoor air pollution classified as a top five environmental danger. Mold, pollen, pet dander, radon and even formaldehyde are commonly found in homes. Since Americans spend about 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 several measures. But first, we need to understand some lingo commonly used to discuss indoor air quality.
HEPA is a term most 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 created—and certified—to confine at least 99.97% of .3-micron particles (smaller than the diameter of a human hair) from the air that filters through the system. This drastically increases your home’s indoor air quality when dust, pollen, mites and other contaminants are trapped.
Minimum efficiency reporting value or MERV describes the effectiveness of an air filter. With metrics ranging from 1–16, you should pursue a max rating that indicates the filter will remove more contaminants and allergens from your air without confining the airflow of your home comfort system. Ask us which MERV-rated filter will work best for your home.
