If you’re shopping for an air purifier, you’ve likely come across the term “CADR” in product descriptions or reviews. But what exactly does CADR mean, and why is it important when it comes to air purifiers?

CADR stands for Clean Air Delivery Rate. It’s a rating system developed by the Association of Home Appliance Manufacturers (AHAM) that measures the amount of clean air a purifier can deliver per minute. Specifically, CADR measures the removal efficiency of three types of pollutants: smoke, pollen, and dust.

The higher the CADR rating, the faster the air purifier can remove these pollutants from the air. For example, a purifier with a CADR rating of 360 for smoke can remove 360 cubic feet of smoke particles per minute.

When shopping for an air purifier, it’s important to consider the CADR rating in relation to the size of the room you’ll be using it in. A higher CADR rating may be necessary for larger rooms or spaces with higher levels of pollution.

It’s also worth noting that CADR ratings are not standardized across all brands or models, so it’s important to compare ratings within the same product category.

In summary, CADR is an important factor to consider when purchasing an air purifier. It measures the speed and efficiency at which a purifier can clean the air in your space, and a higher CADR rating may be necessary for larger rooms or higher pollution levels.
