What You Need to Know About Indoor Air Quality

August 08, 2016

Many people understand how harmful outdoor air pollution like car emissions can be, but they don’t realize that the air inside the typical living space often is more polluted—depending on actual conditions, it can be up to five times more. Things have become so dangerous, the EPA has indoor air pollution tiered 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, good indoor air quality is vital for great health, no matter if it’s in our homes or our workplaces. To help manage this pollution and increase our indoor air quality, we can take different measures. But first, we must to grasp some terms consistently used to discuss indoor air quality.

HEPA

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

MERV

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