What You Need to Know About Indoor Air Quality08/08/2016 The majority of people understand how harmful outdoor air pollution like car emissions can be, but they don’t realize that the air inside the average house might be more polluted—depending 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 in homes. Since Americans spend around 90% of their time indoors, superior indoor air quality is vital for great health, regardless 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 are required 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 trap 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 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 look for a higher rating that indicates 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.
