What CADR do I need for 1000 sq ft?
For wildfire-smoke planning with an 8 ft ceiling, target at least CADR 667. The AHAM 2/3 cross-check is CADR 667.
Required smoke CADR = sqft x ceiling height x ACH / 60
1000 x 8 x 5 / 60 = 667
AHAM 2/3 room-size cross-check: CADR >= 667
1000 x 8 x 5 / 60 = 667
AHAM 2/3 room-size cross-check: CADR >= 667
