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 | 15.6 | 13.9 | Meets AHAM 2/3 rule |
| 150 sq ft | 10.4 | 9.2 | Meets AHAM 2/3 rule |
| 200 sq ft | 7.8 | 6.9 | Meets AHAM 2/3 rule |
| 300 sq ft | 5.2 | 4.6 | Meets AHAM 2/3 rule |
| 400 sq ft | 3.9 | 3.5 | Below AHAM 2/3 rule |
| 500 sq ft | 3.1 | 2.8 | Below AHAM 2/3 rule |
| 700 sq ft | 2.2 | 2.0 | 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 312 sq ft.
