Buying advice: air purifiers
- 1Match the Clean Air Delivery Rate to your room: the purifier should cycle the room's air 4–5× per hour (ACH). Oversize slightly rather than undersize.
- 2True HEPA (H13) captures 99.97% of 0.3-micron particles. 'HEPA-type' or 'HEPA-like' are marketing terms with weaker standards.
- 3A substantial carbon filter helps with odors, VOCs, and smoke. Th in carbon sheets are mostly decorative.
- 4Check dBA at the speed you'll actually run, many units are whisper-quiet on low and loud on the speed that achieves their CADR.
- 5Replacement filters are the real long-term cost. Compare annual filter spend, not just the unit price.
