How many air changes per hour would it give?
Estimate: air changes per hour (ACH) = smoke CADR × 60 ÷ room volume, at the top fan speed used for the CADR test. Real-world ACH is usually lower (lower fan speeds, furniture, filter loading).
| Room | ACH, 8 ft ceiling | ACH, 9 ft ceiling | AHAM sizing |
|---|---|---|---|
| 100 sq ft | 10.9 | 9.7 | Meets AHAM 2/3 rule |
| 150 sq ft | 7.2 | 6.4 | Meets AHAM 2/3 rule |
| 200 sq ft | 5.4 | 4.8 | Meets AHAM 2/3 rule |
| 300 sq ft | 3.6 | 3.2 | Below AHAM 2/3 rule |
| 400 sq ft | 2.7 | 2.4 | Below AHAM 2/3 rule |
| 500 sq ft | 2.2 | 1.9 | Below AHAM 2/3 rule |
| 700 sq ft | 1.6 | 1.4 | Below AHAM 2/3 rule |
AHAM's 2/3 rule: choose a smoke CADR of at least 2/3 of the room's area (8 ft ceiling). By that rule this model suits rooms up to about 218 sq ft.
Estimated yearly electricity cost
| Where | Residential rate | Per year | Per month |
|---|---|---|---|
| Louisiana | 12.72¢ | $13.99 | $1.17 |
| U.S. average | 18.31¢ | $20.14 | $1.68 |
| California | 33.61¢ | $36.97 | $3.08 |
| Hawaii | 48.00¢ | $52.80 | $4.40 |
Estimate = 110 kWh/yr × rate. Rates: EIA Table 5.6.A, July 2026 (preliminary). Filter replacement cost is not included (data gap: not in ENERGY STAR data). Use your own rate and hours.
On battery during an outage (estimate): 110 kWh ÷ 5,840 active hours ≈ 19 W average, which runs slightly high because the annual figure includes standby. A 1,024 Wh portable power station at an assumed 85% inverter efficiency would run it about 46 h. Top fan speed can draw more. Try other stations in the runtime calculator on our power station site.
