What You Need to Know About Indoor Air Quality08/08/2016 Many people understand how harmful outdoor air pollution like car emissions can be, but they don’t realize that the air inside the average living space can 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 in homes. Since Americans spend an average of 90% of their time indoors, superior indoor air quality is crucial for decent health, regardless if it’s in our homes or our workplaces. To help contain this pollution and increase our indoor air quality, we can take different measures. But first, we need to grasp some lingo often 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 engineered—and certified—to confine 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 significantly 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. With ratings ranging from 1–16, you should find a top rating that indicates the filter will destroy more contaminants and allergens from your air without limiting the airflow of your home comfort system. Ask us which MERV-rated filter will work best for your home. At Clean Air HVAC, we can help you understand the importance of indoor air quality and help you work on breathing the best air possible.
