What You Need to Know About Indoor Air Quality

Many people realize how harmful 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 bad, the EPA has indoor air pollution tiered as a top five environmental danger. Mold, pollen, pet dander, radon and even formaldehyde are commonly found in homes. Since Americans spend an average of 90% of their time indoors, excellent indoor air quality is a necessity for good health, regardless if it’s in our homes or our workplaces. To help handle this pollution and increase our indoor air quality, we can take different measures. But first, we are required to grasp some vernacular often used to discuss indoor air quality.

HEPA

HEPA is a term most people have heard or seen, but did you realize 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 (tinier 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.

MERV

Minimum efficiency reporting value or MERV expresses the effectiveness of an air filter. With ratings ranging from 1–16, you should look for a max rating that indicates the filter will destroy more contaminants and allergens from your air without limiting the airflow of your home comfort system. Ask us which MERV-rated filter will work best for your home.
