If you’re an asthma or allergy sufferer, you’ve probably heard about how whole-home air cleaners can ease your pain.
And they can…if you buy the right type, that is.
You see, different whole-home air cleaners use different methods to eliminate different types of contaminants.
So to start your hunt for a whole-home air cleaner, ask yourself “What kind of contaminant am I trying to eliminate?” Then the type of air cleaner you need will become obvious.
In this blog you’ll learn:
Air filter whole-home air cleaner
Pollutants addressed: Particles (includes dust, dust mites, smoke, pollen, animal dander, tobacco smoke.) Can catch some molds, bacteria and viruses.
How it works: There are actually a few types of whole-home air cleaners that fit under this category. Here are the main two:
Limitations: Normally can’t remove larger particles from the air because most settle quickly and never reach filters.
Gas-phase filter whole-home air cleaner
Pollutants addressed: Gases
How it works: Removes gases and odor from your air with a sorbent (a material used to absorb water or gas) that absorbs the pollutants. The kind of sorbents in these filters are also used in gas masks to protect people from harmful gases.
Ultraviolet germicidal irradiation (UVGI) whole-home air cleaners
Pollutants addressed: Biologicals (includes viruses, mold, bacteria)
How it works: Uses ultraviolet radiation from UV lamps to destroy viruses, bacteria, allergens, and molds that are airborne or growing on HVAC surfaces ( e.g., cooling coils, drain pans, or ductwork).
Are there any air cleaners that can eliminate particles, gases and biologicals?
Yes, there are ozone generators. However, according to the Environmental Protection Agency (EPA), ozone generators use a method that intentionally produces ozone. And ozone is a “lung irritant that can cause adverse health effects.”
So we don’t recommend them.
As you can see, it’s important to pick a whole-home air cleaner based on the pollutant you’re concerned about.
Our suggestion: Get an air filter whole-home air cleaner to catch 99% of particulate pollutants in your home, and then complement it with a UVGI if you’re concerned about mold or other biologicals spreading throughout your home.
