What You Need to Know About Indoor Air Quality08/08/2016 The majority of people understand how detrimental outdoor air pollution like car emissions can be, but they don’t realize that the air inside the typical living space 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 inside. Since Americans spend an average of 90% of their time indoors, superior indoor air quality is crucial for decent health, no matter 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 grasp some terms commonly used to discuss indoor air quality. HEPA HEPA is a term a lot of 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 confine 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 greatly increases your home’s indoor air quality when dust, pollen, mites and other contaminants are captured. MERV Minimum efficiency reporting value or MERV describes the effectiveness of an air filter. With rankings ranging from 1–16, you should pursue a max rating that reveals 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.
