MERV 8 Air Filters

90 percent efficiency with particles that are 3 to 10 micrometers in size.

Studies show a MERV 8 filter has proven to be the most common filter on the market. It is effective at controlling dust, pollen, dust mites, and pet dander. Applicable in most commercial buildings, residences, industrial workplaces, and paint booths.

So what does MERV 8 protect against?

In short, MERV 8 blocks particles of 3 microns and larger.

These includes:

  • Dust
  • Pollen
  • Dust mites
  • Bacteria
  • Pet Dander (unless you have more than one pet)

Cigarette smoke, smog, and general allergens would best be handled by MERV 11. While, if bacteria, mold spores, and even wood-burning fireplaces are a concern, then you’d need to look at MERV 13.

Who is the MERV 8 best for?

MERV 8 is the minimum standard air filter we recommend for residential use.

That said, to understand the MERV 8, it’s best to look at what it doesn't protect against. If you have allergies or multiple pets, or other chronic breathing problems, you’ll be best served by going up to MERV 11 or MERV 13.

Or, if you are a smoker (or live with one), or if you live in a city that has smog, you should consider a higher rating, as well.

As you can see, much of which filter you need depends on your lifestyle and what kind of air you regularly come into contact with — or what breathing issues you regularly battle.
