What You Need to Know About Indoor Air Quality08/08/2016 Most people understand how dangerous 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 situations, it can be up to five times more. Things have become so dangerous, the EPA has indoor air pollution tiered 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 great health, regardless if it’s in our homes or our workplaces. To help handle this pollution and better our indoor air quality, we can take several measures. But first, we need to absorb some terms consistently used to discuss indoor air quality. HEPA HEPA is a term most people have heard or seen, but did you recognize 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 (tinier than the diameter of a human hair) from the air that moves 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 ratings ranging from 1–16, you should find a max rating that reveals the filter will remove 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. At B & G HVAC, we can help you understand the importance of indoor air quality and help you work on breathing the best air possible.
