What You Need to Know About Indoor Air Quality

August 08, 2016

Many people realize how dangerous outdoor air pollution like car emissions can be, but they don’t realize that the air inside the usual house often is more polluted—reliant on actual situations, 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 inside. Since Americans spend around 90% of their time indoors, good indoor air quality is a necessity for decent health, despite 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 need to understand some vernacular consistently 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 designed—and certified—to confine at least 99.97% of .3-micron particles (less than the diameter of a human hair) from the air that moves 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 refers to the effectiveness of an air filter. With rankings ranging from 1–16, you should pursue 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.
