What You Need to Know About Indoor Air Quality08/08/2016 Most people realize how dangerous outdoor air pollution like car emissions can be, but they don’t realize that the air inside the average house 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 in homes. Since Americans spend around 90% of their time indoors, superior indoor air quality is vital for great health, despite if it’s in our homes or our workplaces. To help handle this pollution and improve our indoor air quality, we can take different measures. But first, we are required to understand some lingo consistently 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 designed—and certified—to capture at least 99.97% of .3-micron particles (smaller than the diameter of a human hair) from the air that moves through the system. This drastically increases your home’s indoor air quality when dust, pollen, mites and other contaminants are captured. 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 specifies the filter will remove 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.
