What You Need to Know About Indoor Air Quality08/08/2016 The majority of people understand how harmful outdoor air pollution like car emissions can be, but they don’t realize that the air inside the average home can be more polluted—depending on actual situations, it can be up to five times more. Things have become so damaging, the EPA has indoor air pollution classified as a top five environmental danger. Mold, pollen, pet dander, radon and even formaldehyde are commonly found inside. Since Americans spend about 90% of their time indoors, excellent indoor air quality is crucial for great health, despite if it’s in our homes or our workplaces. To help contain this pollution and improve our indoor air quality, we can take different measures. But first, we must to grasp some vernacular often 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 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 greatly increases your home’s indoor air quality when dust, pollen, mites and other contaminants are destroyed. MERV Minimum efficiency reporting value or MERV expresses the effectiveness of an air filter.
