The Clean Air Delivery Rate (CADR) is a measure of an air purifier’s ability to clean the air in a room. To calculate the CADR of an air purifier, you need to know the unit’s airflow rate and the size of the room. The CADR is then calculated by dividing the airflow rate by the room size.

The higher the CADR, the better the air purifier will be at cleaning the air in a room.

- There are a few steps you can take to calculate the CADR for your air purifier: 1
- Look for the CADR rating on the air purifier
- This will be a number between 10 and 400
- Find the square footage of the room you want to use the air purifier in
- Multiply the CADR rating by the square footage of the room
- This will give you the CADR per hour
- Divide the CADR per hour by 60 to get the CADR per minute
- Multiply the CADR per minute by the amount of time you want the air purifier to run
- This will give you the total CADR for the desired time period

## How do you calculate CADR?

When shopping for an air purifier, you may have come across the term “CADR.” CADR stands for Clean Air Delivery Rate and is a measure of an air purifier’s ability to clean the air of specific types of pollutants. The higher the CADR, the more effective the air purifier.

To calculate the CADR of an air purifier, you first need to know the unit’s airflow rate and the size of the room it’s meant to purify. The airflow rate is usually listed in cubic feet per minute (cfm). Once you have those two numbers, you can plug them into the following formula:

CADR = (airflow rate in cfm) x (room size in square feet) / 48
For example, let’s say you have an air purifier with a airflow rate of 200 cfm and you want to use it in a room that is 500 square feet.
