What You Need to Know About Indoor Air Quality

The majority of people understand how detrimental outdoor air pollution like car emissions can be, but they don’t realize that the air inside the typical house might be more polluted—contingent on actual circumstances, 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 indoors. Since Americans spend around 90% of their time indoors, good indoor air quality is crucial for great health, despite if it’s in our homes or our workplaces. To help handle this pollution and better our indoor air quality, we can take multiple measures. But first, we are required to understand some lingo consistently used to discuss indoor air quality.

HEPA

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 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 moves through the system. This greatly 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 look for a higher rating that specifies 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.
