Air purifiers have become hugely popular in the past couple of years and there is a reason for it: They help build a healthy home environment by eliminating dust, allergens, pet dander and other airborne contaminates that affect health.

The Dreo HEPA Air Purifier typically retails for $180, but you can catch it on sale for just $66 during Walmart Deals week. It's small enough to fit practically anywhere (think an end table or desk) and shoppers say this "powerful little thing" is "super quiet."

I never wanted a big air purifier in my living room – until I saw Blueair’s new Blue Signature, which combines top-tier filtration and sleek style.

These are the best air purifiers for pets, from Levoit Vital 200S and AirDoctor AD3500 to SwitchBot Table Air Purifier.

The most effective filters have what’s called high-efficiency particulate air certification. Better known as HEPA filters, they can capture up to 99.97 percent of common particle pollutants like mold, dust, pet dander, pollen and smoke.

Compared to other air cleaners, the Rabbit Air BioGS 2.0 Air Purifier makes a loud statement by being quiet and unobtrusive. All of this while monitoring the atmosphere and ramping up its action during an air quality crisis.

One early deal to have on your radar is the $180 Bissell Air180 Air Purifier, which is on sale at Amazon right now for only $84. Shoppers are pleased with its performance, calling it a "workhorse for allergy relief." Get it.

I tried three different purifiers, which were all clunky or not quite effective, before I finally found one that I love and would recommend to anyone sniffing and suffering their way through allergies: the PuroAir 240 HEPA Air Purifier.
