What You Need to Know About Indoor Air Quality08/08/2016We all recognize the dangers of outdoor air pollution, such as car emissions. What a lot of people don’t know is that the air inside the average home is nearly five times more polluted than outside air. Indoor air quality is important because Americans spend approximately 90% of their time indoors, whether they are at home or running errands. The EPA has ranked indoor air pollution in the top five environmental concerns. A couple of the usual indoor pollutants include: mold, pollen, pet dander, radon and even formaldehyde. There are also a few common terms normally used when discussing indoor air quality, so make sure you understand these: HEPA You’ve likely seen or heard this term used, but do you grasp 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 passes through the system. Dust, pollen, mites and other contaminants can all be captured, greatly boosting your home’s indoor air quality. MERV MERV is short for “minimum efficiency reporting value” or put in easier terms, it tells you the effectiveness of your air filter. MERV ratings can be anywhere from 1-16 with the higher rating removing more contaminants and allergens without inhibiting the airflow of your home comfort system. We can work with you to figure out a filter with a MERV rating that will work best for your home. We breathe on average 11,000 liters of air a day.
