What You Need to Know About Indoor Air Quality08/08/2016We all hear about the dangers of outdoor air pollution, such as car emissions. What a lot of people don’t realize is that the air inside the regular home is nearly five times more polluted than outside air. Indoor air quality is important because Americans spend nearly 90% of their time indoors, whether it is at home or in the office. The EPA has ranked indoor air pollution in the top five environmental concerns. A couple normal indoor pollutants include: mold, pollen, pet dander, radon and even formaldehyde. There are also a few common terms regularly used when talking about indoor air quality, so make sure know about these: HEPA You’ve likely seen or heard this term used, but do you understand what it means? HEPA 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 (.000012” or 300x smaller than the diameter of human hair) particles from the air that heads through the system. Dust, pollen, mites and other contaminants can all be captured, greatly improving your home’s indoor air quality. MERV MERV is a shortened version of “minimum efficiency reporting value” or put in easier terms, it tells you the effectiveness of your air filter. MERV ratings can range from 1-16 with the higher rating eliminating more contaminants and allergens without impacting the airflow of your home comfort system.
