Energy Star Certification for Air Purifiers
Air purifiers are designed to run 24 hours a day, 365 days a year. An inefficient model running on high speed can consume over 90 watts continuously, adding $120+ annually to your electric bill. The EPA's Energy Star program certifies purifiers meeting strict CADR-per-watt efficiency thresholds.
Energy Efficiency Benchmarks
| CADR Range | Energy Star Min CADR/Watt | Typical DC Motor Wattage |
|---|---|---|
| Smoke CADR < 100 | 1.9 CADR / Watt | 10 – 25 Watts |
| Smoke CADR 100 – 150 | 2.4 CADR / Watt | 25 – 40 Watts |
| Smoke CADR > 150 | 2.9 CADR / Watt | 35 – 55 Watts |
