10 Best Guardian Air Purifiers
for December 2022

MOOZ's editors select recommendations independently. Purchases made through our links may earn us commissions.

Our air purifying experts have tested 10 of the top air purifiers on the market. We tested these appliances for their air cleaning performance, noise level, and ease of use. By testing these purifiers in a challenging home environment with commercial-grade allergens, our team was able to properly assess their performance. By combining this real-world testing with laboratory-style analysis, we were able to determine the best air purifier models based on our findings.

Air purifiers clear the air of contaminants, including dust, mold, pet dander, and toxins. A portable air purifier can be an effective way to remove these contaminants when confined to a small home area. Our selection of purifiers is comprehensive, ranging from portable pocket units to wall-mounted purifiers, so there's a model suited for your needs.
