What You Need to Know About Indoor Air Quality08/08/2016 Many people realize how harmful outdoor air pollution like car emissions can be, but they don’t realize that the air inside the usual living space might be more polluted—depending on actual conditions, it can be up to five times more. Things have become so dangerous, 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 manage this pollution and improve our indoor air quality, we can take different measures. But first, we need to absorb some lingo commonly 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 trap at least 99.97% of .3-micron particles (less 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 captured. MERV Minimum efficiency reporting value or MERV expresses the effectiveness of an air filter. With metrics ranging from 1–16, you should pursue a top rating that reveals the filter will destroy 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.
