CADR

$\mathrm{CADR}=\mathrm{air}\mathrm{flow}\cdot \mathrm{filter}\mathrm{efficiency}$

• Airflow is in cubic feet per minute

$\mathrm{CAD}{\mathrm{R}}_{\text{min}}=\frac{2}{3}{A}_{\text{room}}$

• The area of the room may be measured in square feet
• E.g. a 10x10 ft room would require a CADR of 66

$\mathrm{CAD}{\mathrm{R}}_{\text{min}}=3V_{\text{room}}$

• The volume of the room measured in cubic meters
• E.g. a 10x10x8 ft room would require a CADR of 67
