The 6 Best Air Purifiers Of 2023 To Help You Tackle Germs, Dust, Smoke, Mold & Pet Dander

The GermGuardian AC4825E is a 4-in-1 air purifier that uses a 3-stage filtration process to capture dust and allergens, kill airborne mold and germs, and reduce odor. Air first passes through the purifier's activated charcoal pre-filter, which captures dust, pet hair, and other large particles, while also removing odors from the air. The True HEPA filter then captures 99.97% of the remaining allergens—including even more dust particles. Lastly, the optional UV-C light with combined TIO2 treatment can be used to reduce airborne bacteria, viruses, mold, and VOCs from the air.

What Customers Say:

The GermGuardian AC4825E has an overall 4.7/5.0 rating on Walmart's website. One reviewer raved about how impressed she was, stating "Came across this as I searched online about keeping the dust down. Went from needing to dust AT LEAST 2x week, to every 2-3 weeks." Another reviewer shared, "The reduction in dust in the room over a two week period is astounding."

The EnviroKlenz Mobile UV Model uses a 3-stage filtration process to not only capture but also destroy air contaminants, including pet dander, pollen, mold, smoke, odors, and chemicals. As air passes through the purifier, the EnviroKlenz air cartridge captures viruses, bacteria, and chemicals, which are then broken down in the system. The air then continues through the HEPA filter, which captures dust, dander, pollen, and more. Meanwhile, the UV-C lights destroy microscopic contaminants from the HEPA filter, as well as the purifier's interior, making it an excellent option to help protect against the spread of viruses.
