What Are Air Cleaners for Allergies?

Simply put, air purifiers are standalone devices placed throughout the home whose function is to sanitize the air by filtering harmful air particles out of the air you breathe.

See our related post, How Does an Air Purifier Work? for a more detailed explanation.

Air cleaners can be especially helpful when dealing with indoor allergies. Not only can indoor allergies happen year-round, but according to the Environmental Protection Agency, the concentration of pollutants indoors can be five times higher than outdoors.

Common causes of indoor allergens include dust mites and pet allergens. When selecting an air cleaner specifically to help with allergies, there are a few things to consider (more on that below).

What Are the Different Types of Air Cleaners for Allergies?

There are different types of air cleaners, and there’s some nuance you should understand before purchasing one specifically for allergies.

The two main categories of air cleaners are particle filter air cleaners that help remove pollutants from the air as described above, and activated carbon that is more focused on removing gases and odors.

Most air cleaners have both filters, but if you’re specifically looking for an air cleaner to help with allergies, be sure your air cleaner has a top-rated particle filter!

Not all particle filters are created equal, though. What you want to look for is a filter with a “HEPA” designation (HEPA stands for “high efficiency particle air” filter).

These filters meet rigorous standards to ensure they can remove some of the smallest air particles from the air.

Other acronyms you’re likely to run into are “CADR” (which stands for Clean Air Delivery Rate), and “CFM” (Cubic Feet per Minute).

CADR is a measure of how efficiently and effectively the air cleaner processes and sanitizes air, and it’s expressed in cubic feet per minute.

Generally, when it comes to air purifiers, a higher CADR means the air purifier can sanitize air more quickly, and can cover more area. These units usually draw more power, though, so that can be an important consideration to make sure you don’t wind up with any surprises on your next electric bill.
