What You Need to Know About Indoor Air Quality

Most people understand how dangerous outdoor air pollution like car emissions can be, but they don’t realize that the air inside the usual home often is more polluted—reliant on actual conditions, it can be up to five times more. Things have become so damaging, the EPA has indoor air pollution classified 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, no matter if it’s in our homes or our workplaces. To help contain this pollution and improve our indoor air quality, we can take multiple measures. But first, we need to understand some terms 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 trap at least 99.97% of .3-micron particles (less 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 destroyed.

MERV

Minimum efficiency reporting value or MERV describes the effectiveness of an air filter. With rankings ranging from 1–16, you should pursue a top 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.
