What You Need to Know About Indoor Air Quality

Most people are aware of how dangerous outdoor air pollution like car emissions can be, but they don’t realize that the air inside the average living space often is more polluted—contingent on actual situations, it can be up to five times more. Things have become so damaging, the EPA has indoor air pollution tiered as a top five environmental danger. Mold, pollen, pet dander, radon and even formaldehyde are commonly found indoors. Since Americans spend an average of 90% of their time indoors, superior indoor air quality is a necessity for good health, regardless if it’s in our homes or our workplaces. To help manage this pollution and increase our indoor air quality, we can take multiple measures. But first, we must to understand some terms commonly used to discuss indoor air quality.

HEPA

HEPA is a term a lot of 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 engineered—and certified—to trap at least 99.97% of .3-micron particles (smaller 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 metrics ranging from 1–16, you should look for a higher rating that specifies the filter will filter more contaminants and allergens from your air without restricting the airflow of your home comfort system. Ask us which MERV-rated filter will work best for your home.
