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 know 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 nearly 90% of their time indoors, whether it is at home or in a store. The EPA has ranked indoor air pollution in the top five environmental dangers. A couple of the usual indoor pollutants include: mold, pollen, pet dander, radon and even formaldehyde. There are also some common terms normally used when talking about indoor air quality, so make sure you’re familiar with 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 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 a shortened version of “minimum efficiency reporting value” or put in easier terms, it states the effectiveness of your air filter. MERV ratings can range from 1-16 with the higher rating getting rid of more contaminants and allergens without impacting the airflow of your home comfort system. We can work with you to determine a filter with a MERV rating that will work best for your system. We breathe on average 11,000 liters of air a day.
