Honeywell HPA300 Review
A no-frills, high-CADR workhorse from Honeywell — AHAM-verified CADR 300 for dust, covers up to 465 sq ft, and one of the strongest performers under $250 for large rooms.

Our Verdict
The Honeywell HPA300 is built for one purpose: moving a lot of air through a HEPA filter in a large space, reliably and simply. Its CADR 300 dust rating and 5-year warranty are hard to match at this price. The trade-off is noise and power draw — this is not a bedroom purifier. For large living rooms, open-plan spaces, or post-wildfire smoke recovery, it's a strong choice.
