What You Need to Know About Indoor Air Quality08/08/2016 Most people are aware of how harmful outdoor air pollution like car emissions can be, but they don’t realize that the air inside the typical living space 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 classified as a top five environmental danger. Mold, pollen, pet dander, radon and even formaldehyde are commonly found indoors. Since Americans spend around 90% of their time indoors, good indoor air quality is a necessity for great health, despite if it’s in our homes or our workplaces. To help manage this pollution and better our indoor air quality, we can take different measures. But first, we are required to understand some terms commonly 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 created—and certified—to capture at least 99.97% of .3-micron particles (smaller than the diameter of a human hair) from the air that passes through the system. This greatly increases your home’s indoor air quality when dust, pollen, mites and other contaminants are trapped. MERV Minimum efficiency reporting value or MERV refers to the effectiveness of an air filter. With rankings ranging from 1–16, you should look for a max 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.
