Show the sizing rule & unknowns

AHAM’s everyday rule is room area in ft² × ⅔; for smoke season, use area × 1. The smoke CADR target is rounded upward. It is a planning calculation for a standard ceiling, not a product specification or measured performance.

No positive verdict is given for taller ceilings or quiet settings. A CADR with no pollutant label cannot be used as smoke CADR.
