Honeywell HPA300 (HEPA) review 2026

A big, plain HEPA box with 465 sq ft coverage and three HEPA filters inside — strong, loud and not smart

Is the Honeywell HPA300 Worth It?

Most airflow under $250. The HPA300 pushes a lot of air through good filters and does nothing else. In a room where noise does not matter it is a bargain; in a bedroom it is not an option.

Honeywell HPA300 Pros & Cons

Pros
  • CADR 300 for $250
  • Cleared our room in 12 minutes
  • Three HEPA filters last a year
  • Widely available
Cons
  • Loudest here on every setting — 33 dB on low, 62 on turbo
  • No sensor or auto mode
  • Carbon pre-filter does nothing for smells
