“ Compare CADR, CCM, room coverage, noise, energy efficiency, purification technology, convenience features, and the types of pollutants an air purifier can remove. ”

Consider these eight points when choosing an air purifier:

1. Check the particulate CADR and formaldehyde CADR. In general, higher values indicate faster purification.

2. Check the particulate CCM and formaldehyde CCM ratings. Prefer products that reach the highest P4 and F4 levels.

3. Check the recommended room area. CADR can be converted into a suggested coverage area using the formula in the applicable national standard: suitable area = 0.07–0.12 × particulate CADR.

4. Compare noise levels. In general, lower minimum-setting noise is preferable. For reference, falling leaves are around 25 dB and a library is around 45 dB.

5. Check energy efficiency. Energy efficiency is calculated as CADR divided by rated power. A higher CADR and lower rated power mean lower electricity consumption. A value above 11 may qualify as Grade 1 energy efficiency.

6. Review active purification features, such as negative ions, plasma, deep-UV lamps, catalytic filter materials, and high-efficiency HEPA filters.

7. Consider convenience features, including voice control, remote control through a mobile app, a PM2.5 sensor, an intelligent light sensor, a handheld remote, carrying handles, casters, and combined purification and humidification.

8. Check the pollutant types addressed, such as particles, gaseous pollutants, allergens, viruses, and bacteria.
