Expert Pick #08
Honeywell HPA300.
True HEPA filtration moving air 5x per hour in 320 sq ft rooms with simple manual controls.
The Verdict.
7.7/ 10
Gavler Meta-Score
“The HPA300 is proof that effective air purification doesn't require a smart home degree. It's loud on turbo, it's not pretty, and it won't connect to Alexa. But it moves more air through a HEPA filter per dollar than almost any other purifier on the market. For dorm rooms, workshops, basements, or anyone who just wants clean air without the complexity, the HPA300 is the pragmatic choice.”
