What You Need to Know About Indoor Air Quality

Many people are aware of how harmful outdoor air pollution like car emissions can be, but they don’t realize that the air inside the usual living space can be more polluted—reliant on actual circumstances, it can be up to five times more. Things have become so bad, the EPA has indoor air pollution tiered as a top five environmental danger. Mold, pollen, pet dander, radon and even formaldehyde are commonly found indoors. Since Americans spend around 90% of their time indoors, good indoor air quality is crucial for good health, regardless 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 are required to absorb some terms commonly used to discuss indoor air quality.

HEPA

HEPA is a term a lot of 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 created—and certified—to confine at least 99.97% of .3-micron particles (less than the diameter of a human hair) from the air that passes through the system. This greatly 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 reveals the filter will remove 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.
