What is the Clean Air Delivery Rate of the air purifier

What is the CADR (Clean Air Delivery Rate) of the air purifier?

When shopping for air purifiers, customers may come across the term CADR, which stands for Clean Air Delivery Rate. The CADR is a measure of how effectively an air purifier can clean the air in a room, and it’s an important factor to consider when choosing an air purifier. Here’s what you need to know about the CADR and how to interpret it:

What is the CADR?

The CADR measures the amount of clean air that an air purifier can deliver into a room. It’s typically measured in cubic feet per minute (CFM). The higher the CADR rating, the more effective the air purifier is at cleaning the air in a room.

How is the CADR determined?

The CADR is determined through testing by independent organizations such as the Association of Home Appliance Manufacturers (AHAM). During testing, an air purifier is placed in a room and exposed to a specific level of pollutants. The amount of clean air that the air purifier delivers back into the room is then measured and used to determine the CADR rating.

What do the CADR ratings mean?

The CADR rating is typically given for three types of pollutants: smoke, pollen, and dust. The higher the CADR rating for a specific pollutant, the more effective the air purifier is at removing that pollutant from the air.

For example, if an air purifier has a CADR rating of 200 for smoke, it means that it can remove 200 cubic feet of smoke per minute from the air in a room. Similarly, if an air purifier has a CADR rating of 300 for pollen, it means that it can remove 300 cubic feet of pollen per minute from the air in a room.

How do I use the CADR when choosing an air purifier?

When choosing an air purifier, look for models with CADR ratings that are appropriate for the size of your room and the level of pollutants in your environment. The AHAM recommends choosing an air purifier with a CADR rating that is at least two-thirds of the size of your room for optimal performance.

For example, if you have a 300 square foot room, look for an air purifier with a CADR rating of at least 200 for each pollutant. This will ensure that the air purifier can effectively clean the air in your room.

Other Factors to Consider

While the CADR is an important factor to consider when choosing an air purifier, it’s not the only factor. Other factors to consider include the type of filter used in the air purifier, the size of the room, and the noise level of the device. Be sure to read product specifications and customer reviews to find an air purifier that meets your needs and preferences.
