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 average 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 they are at home or in the office. The EPA has ranked indoor air pollution in the top five environmental hazards. A few 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 you’re familiar with these: HEPA You’ve probably 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 produced 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 pollutants can all be captured, greatly improving your home’s indoor air quality. MERV MERV is short for “minimum efficiency reporting value” or put in easier terms, it says the effectiveness of your air filter. MERV ratings can be between 1-16 with the higher rating getting rid of more contaminants and allergens without inhibiting 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 needs. We breathe on average 11,000 liters of air a day.
