AC4825

The AC4825 answers the question: what is the absolute cheapest effective air purifier? At $90 for 167 sq ft coverage, it is even cheaper than the Levoit Core 300. Trade-offs include smaller coverage and UV-C light that should be disabled.

Overall Score: 7.8/10 - Ultra Budget Pick

True HEPA

Genuine HEPA filtration at rock-bottom pricing.

UV-C Caveat

The UV-C light feature can be kept off. Some UV-C lights produce trace ozone, so I recommend operating without it.

Coverage: 167 sq ft

Very small room only - a child bedroom or small office.

CADR: 100 CFM

Modest but sufficient for small coverage area.

At $90, exceptional entry-level value.

Final Score: 7.8/10
