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 average home often is more polluted—reliant on actual circumstances, 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 an average of 90% of their time indoors, superior indoor air quality is vital for good health, despite if it’s in our homes or our workplaces. To help handle this pollution and improve our indoor air quality, we can take several measures. But first, we are required to understand some vernacular commonly used to discuss indoor air quality. HEPA HEPA is a term a lot of 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 engineered—and certified—to trap at least 99.97% of .3-micron particles (tinier 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 trapped. MERV Minimum efficiency reporting value or MERV refers to the effectiveness of an air filter. With rankings ranging from 1–16, you should find a top rating that indicates the filter will filter more contaminants and allergens from your air without limiting the airflow of your home comfort system. Ask us which MERV-rated filter will work best for your home.
