GermGuardian AC4825
The GermGuardian AC4825 is the best-reviewed air purifier under $100 by a wide margin — 54,000 owners with strong long-term satisfaction data don't lie. It won't cover a large room effectively, but in a bedroom or small office (under 150 sq. ft.), its combination of True HEPA, UV-C germicidal light, and carbon filtration delivers meaningful air quality improvement.
