What You Need to Know About Indoor Air Quality08/08/2016 Most people realize how harmful outdoor air pollution like car emissions can be, but they don’t realize that the air inside the average house might be more polluted—contingent on actual conditions, it can be up to five times more. Things have become so damaging, the EPA has indoor air pollution tiered as a top five environmental danger. Mold, pollen, pet dander, radon and even formaldehyde are commonly found inside. Since Americans spend around 90% of their time indoors, excellent indoor air quality is vital for good health, no matter if it’s in our homes or our workplaces. To help contain this pollution and better our indoor air quality, we can take several measures. But first, we are required to understand some terms commonly used to discuss indoor air quality. HEPA HEPA is a term most 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 (tinier 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 metrics ranging from 1–16, you should look for a max rating that indicates the filter will filter 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.
