Best Air Purifiers Under $50

While it does a great job as an overall air purifier, we believe pet owners will benefit most from its odor-trapping filtration system.

HEPA filter designed for long-term use. Includes two carbon zeolite filters for pet odors. Effective range up to 140 sq. ft. Works in vertical or horizontal positions. Captures particles as small as 3 microns.

Small Room 3-Speed HEPA Air Purifier

Fan is noisy. Exhaust port close to air intake - not an efficient design.
