Air Changes Per Hour (ACH) Calculator
ACH Calculation Formula
\[ ACH = \frac{CFM \times 60}{\text{Area} \times \text{Height}} \]
Where:
\( ACH \) = Air changes per hour
\( CFM \) = Cubic feet per minute of air flow
\( \text{Area} \) = Area of the room (square feet)
\( \text{Height} \) = Height of the room (feet)
Air Flow (CFM):
Area of the Room (sq ft):
Height of the Room (ft):
