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 usual house can be more polluted—reliant on actual situations, it can be up to five times more. Things have become so bad, 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 vital for decent health, no matter if it’s in our homes or our workplaces. To help handle this pollution and better our indoor air quality, we can take several measures. But first, we need to understand some lingo consistently 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 designed—and certified—to capture 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 significantly increases your home’s indoor air quality when dust, pollen, mites and other contaminants are captured.

MERV

Minimum efficiency reporting value or MERV describes the effectiveness of an air filter. With ratings ranging from 1–16, you should pursue a max rating that specifies the filter will filter 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.
