What You Need to Know About Indoor Air Quality

The majority of people realize how dangerous outdoor air pollution like car emissions can be, but they don’t realize that the air inside the average house might be more polluted—contingent on actual circumstances, it can be up to five times more. Things have become so dangerous, the EPA has indoor air pollution ranked as a top five environmental danger. Mold, pollen, pet dander, radon and even formaldehyde are commonly found in homes. Since Americans spend around 90% of their time indoors, superior indoor air quality is vital for great health, despite if it’s in our homes or our workplaces. To help manage this pollution and better our indoor air quality, we can take multiple measures. But first, we need to grasp some vernacular often used to discuss indoor air quality.


HEPA is a term most people have heard or seen, but did you realize it stands for “high-efficiency particulate air” or “high-efficiency particulate arrestance”? HEPA filtration systems are designed—and certified—to confine at least 99.97% of .3-micron particles (tinier than the diameter of a human hair) from the air that passes through the system. This drastically increases your home’s indoor air quality when dust, pollen, mites and other contaminants are captured.


Minimum efficiency reporting value or MERV describes the effectiveness of an air filter. With ratings ranging from 1–16, you should pursue a top rating that indicates the filter will destroy more contaminants and allergens from your air without restricting the airflow of your home comfort system. Ask us which MERV-rated filter will work best for your home.
