What You Need to Know About Indoor Air Quality

Air Quality

Many people understand how harmful outdoor air pollution like car emissions can be, but they don’t realize that the air inside the usual living space can be more polluted—contingent on actual situations, it can be up to five times more. Things have become so dangerous, 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 about 90% of their time indoors, excellent indoor air quality is crucial for great health, no matter if it’s in our homes or our workplaces. To help handle this pollution and improve our indoor air quality, we can take several measures. But first, we are required to understand some terms 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 designed—and certified—to confine at least 99.97% of .3-micron particles (smaller than the diameter of a human hair) from the air that filters through the system. This greatly increases your home’s indoor air quality when dust, pollen, mites and other contaminants are captured.

MERV

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