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 | 4.0 | 3.6 | Below AHAM 2/3 rule |
| 150 sq ft | 2.7 | 2.4 | Below AHAM 2/3 rule |
| 200 sq ft | 2.0 | 1.8 | Below AHAM 2/3 rule |
| 300 sq ft | 1.4 | 1.2 | Below AHAM 2/3 rule |
| 400 sq ft | 1.0 | 0.9 | Below AHAM 2/3 rule |
| 500 sq ft | 0.8 | 0.7 | Below AHAM 2/3 rule |
| 700 sq ft | 0.6 | 0.5 | 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 81 sq ft.
