We all recognize 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 approximately five times more polluted than outside air. Indoor air quality is important because Americans spend approximately 90% of their time indoors, whether it’s at home or in the office. The EPA has ranked indoor air pollution in the top five environmental dangers. Some common indoor pollutants include: mold, pollen, pet dander, radon and even formaldehyde. There are also a couple common terms traditionally used when discussing indoor air quality, so make sure you’re familiar with these:
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 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 goes through the system. Dust, pollen, mites and other pollutants can all be captured, greatly boosting your home’s indoor air quality.
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 between 1-16 with the higher rating removing more contaminants and allergens without restricting 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. We want to help you recognize the importance of indoor air quality and help ensure the air you’re breathing is good for your health.
