How to Calculate the Right CADR for Your Space
To find the right CADR for your space, start by measuring the room’s dimensions to calculate its volume accurately. Then, determine the needed air changes per hour to keep the air clean, usually at least three times per hour. With these numbers, you can choose an air purifier that effectively covers your room’s size and air quality needs. Additionally, consider the filter grade to ensure it matches your specific air purification requirements for allergens or pollutants. Remember that quality fatherhood advice and understanding can also help create a healthier environment.
Room Size and Volume
Calculating the right CADR for your space starts with understanding your room’s size and volume. Measure the length, width, and height in feet or meters, then multiply these to find the volume. For example, a 12 ft × 10 ft × 8 ft room has a volume of 960 cubic feet. To guarantee effective air cleaning, multiply this volume by 3 for the minimum CADR in m³/hr, or convert cubic feet to cubic meters (divide by 35.3). Use the table below to interpret your room characteristics and CADR needs:
| Room Size | Volume Calculation | Recommended CADR |
|---|---|---|
| Small (~200 sq ft) | Length × Width × Height | Lower CADR, desktop models |
| Medium (201-399 sq ft) | Same calculation | Mid-range units |
| Large (400+ sq ft) | Sum of multiple sections | High CADR or multiple units |
Additionally, understanding room volume helps determine the appropriate air purifier for your needs, especially when considering filter grades and their effectiveness in various room sizes.
Air Changes per Hour
Understanding air changes per hour (ACH) helps you gauge how effectively your room’s air circulates and refreshes. To calculate ACH, you need to know your room’s volume and your air purifier’s CADR. The formula is ACH = (CADR x 60) / Room Volume. A higher ACH means better air circulation and improved air quality. To find the right CADR, consider your room size and desired air refresh rate.
