Required Airflow
0 CFM
Understanding CFM Calculation
CFM (Cubic Feet per Minute) is a measure of air flow rate used in heating, ventilation, and air conditioning (HVAC) systems. Proper air flow is crucial for maintaining good indoor air quality and comfort.
Recommended Air Changes per Hour (ACH)
- Living Rooms: 3-4 ACH
- Bedrooms: 5-6 ACH
- Kitchens: 7-8 ACH
- Bathrooms: 7-8 ACH
- Laundry Rooms: 8-9 ACH
Formula
CFM = (Room Volume × Air Changes per Hour) ÷ 60
