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).

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 692 sq ft.

Estimated yearly electricity cost

U.S. average18.31¢$88.99$7.42

Estimate = 486 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): 486 kWh ÷ 5,840 active hours ≈ 83 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 10 h. Top fan speed can draw more. Try other stations in the runtime calculator on our power station site.
