What You Need to Know About Indoor Air Quality08/08/2016 Many people understand how harmful outdoor air pollution like car emissions can be, but they don’t realize that the air inside the usual house might be more polluted—contingent on actual conditions, 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 vital for decent health, despite if it’s in our homes or our workplaces. To help manage this pollution and improve our indoor air quality, we can take several measures. But first, we are required to absorb some terms commonly 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 created—and certified—to capture 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 drastically increases your home’s indoor air quality when dust, pollen, mites and other contaminants are trapped. MERV Minimum efficiency reporting value or MERV describes the effectiveness of an air filter. With rankings ranging from 1–16, you should find a top rating that specifies 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.
