What You Need to Know About Indoor Air Quality

Most people realize how dangerous outdoor air pollution like car emissions can be, but they don’t realize that the air inside the typical house often is more polluted—contingent on actual situations, it can be up to five times more. Things have become so dangerous, the EPA has indoor air pollution tiered as a top five environmental danger. Mold, pollen, pet dander, radon and even formaldehyde are commonly found inside. Since Americans spend an average of 90% of their time indoors, excellent indoor air quality is a necessity for great 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 multiple measures. But first, we are required to grasp some lingo commonly used to discuss indoor air quality.

HEPA

HEPA is a term many 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 trap at least 99.97% of .3-micron particles (tinier than the diameter of a human hair) from the air that passes through the system. This drastically increases your home’s indoor air quality when dust, pollen, mites and other contaminants are trapped.

MERV

Minimum efficiency reporting value or MERV expresses the effectiveness of an air filter. With rankings ranging from 1–16, you should find a higher rating that specifies 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.
