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 know is that the air inside the normal home is around five times more polluted than outside air. Indoor air quality is important because Americans spend nearly 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 hazards. A few of the usual indoor pollutants include: mold, pollen, pet dander, radon and even formaldehyde. There are also a couple common terms traditionally used when speaking about indoor air quality, so make sure you understand these: HEPA You’ve possibly 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 manufactured 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 boosting your home’s indoor air quality. MERV MERV is short for “minimum efficiency reporting value” or put in simple terms, it states the effectiveness of your air filter. MERV ratings can be between 1-16 with the higher rating eliminating more contaminants and allergens without impacting 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 system. We breathe on average 11,000 liters of air a day.
