What You Need to Know About Indoor Air Quality08/08/2016 Most people are aware of how detrimental outdoor air pollution like car emissions can be, but they don’t realize that the air inside the usual house can be more polluted—depending on actual circumstances, it can be up to five times more. Things have become so damaging, the EPA has indoor air pollution ranked 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, good indoor air quality is vital for decent 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 grasp some lingo often used to discuss indoor air quality. HEPA HEPA is a term many 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 engineered—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 significantly increases your home’s indoor air quality when dust, pollen, mites and other contaminants are destroyed. MERV Minimum efficiency reporting value or MERV describes the effectiveness of an air filter. With ratings ranging from 1–16, you should look for 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.
