What You Need to Know About Indoor Air Quality08/08/2016 The majority of people realize how detrimental outdoor air pollution like car emissions can be, but they don’t realize that the air inside the typical home can be more polluted—depending on actual situations, it can be up to five times more. Things have become so dangerous, 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 crucial for decent health, no matter if it’s in our homes or our workplaces. To help handle this pollution and improve our indoor air quality, we can take different measures. But first, we need to understand some lingo consistently used to discuss indoor air quality. HEPA HEPA is a term most people have heard or seen, but did you realize it stands for “high-efficiency particulate air” or “high-efficiency particulate arrestance”? HEPA filtration systems are created—and certified—to trap at least 99.97% of .3-micron particles (less 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 destroyed. 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 max rating that indicates the filter will filter 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.
