What You Need to Know About Indoor Air Quality08/08/2016We all know the dangers of outdoor air pollution, such as car emissions. What a lot of people don’t recognize is that the air inside the normal home is approximately five times more polluted than outside air. Indoor air quality is important because Americans spend around 90% of their time indoors, whether they are at home or in the office. The EPA has ranked indoor air pollution in the top five environmental concerns. A couple common indoor pollutants include: mold, pollen, pet dander, radon and even formaldehyde. There are also some common terms normally used when speaking about indoor air quality, so make sure you understand these: HEPA You’ve likely seen or heard this term used, but do you know 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 goes through the system. Dust, pollen, mites and other impurities can all be captured, greatly boosting your home’s indoor air quality. MERV MERV is a shortened version of “minimum efficiency reporting value” or put in simple terms, it says the effectiveness of your air filter. MERV ratings can be anywhere from 1-16 with the higher rating getting rid of more contaminants and allergens without impacting the airflow of your home comfort system.
