What CADR do I need for 1500 sq ft?
For wildfire-smoke planning with an 8 ft ceiling, target at least CADR 1000. The AHAM 2/3 cross-check is CADR 1000.
Required smoke CADR = sqft x ceiling height x ACH / 60
1500 x 8 x 5 / 60 = 1000
AHAM 2/3 room-size cross-check: CADR >= 1000
1500 x 8 x 5 / 60 = 1000
AHAM 2/3 room-size cross-check: CADR >= 1000
