What You Need to Know About Indoor Air Quality08/08/2016 Most people understand how harmful outdoor air pollution like car emissions can be, but they don’t realize that the air inside the usual home might be more polluted—reliant 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, excellent indoor air quality is vital for great health, despite if it’s in our homes or our workplaces. To help handle this pollution and better our indoor air quality, we can take several measures. But first, we are required to grasp some vernacular often used to discuss indoor air quality. HEPA HEPA is a term many 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 (less than the diameter of a human hair) from the air that moves 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 ratings ranging from 1–16, you should pursue a higher 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.
