When looking for an air purifier, one of the things you must consider is the CADR rating of the unit. An air purifier is only as effective as its CADR ratings – the higher the scores, the bigger the space your air purifier will be capable of cleaning. For that reason, you will want your air purifier to have the highest CADR ratings in the market. But that’s going to depend on your needs. If you living is small, or you intended to only use the device in bedrooms or any other small space, It won’t make sense to buy an air purifier with CADR rating of say, 400 cfm. In this article, we will talk about the CADR ratings and the seven best high CADR air purifier with their capabilities, features with pros and cons.

The market has air purifiers with the right CADR rating for everyone. Before talking about the list, let’s have a more in-depth look into what CADR is:
Understanding the CADR: To determine the rate of work or efficiency of any machine, we often measure the amount of work done by the device in a given time. CADR or Clean Air Delivery Rate is the amount of filtered air delivered from an air purifier in a certain timeframe. Commonly it expresses as cubic feet per minute (cfm) or cubic meter per hour (m3/h).
Hence, CADR can be to air purifiers what horsepower is to car engines. From the CADR ratings, you can easily find out how much you will get from an air purifier for your specific room size. Also, you can find out how much CADR you will be needed for certain types of cleaning in your home.
Calculate: How much CADR do I need for my room?
The Association of Home Appliances Manufacturers (AHAM) tests air purifiers’ ability to clean smoke, dust, and pollen from the air. AHAM would, therefore, print the CADR rating to tell the buyers more about the device’s capabilities to eliminate smoke, dust, and pollen contaminants, which represent tiny, medium, and larger particles comparatively. Some manufacturers listed their air purifiers by their self tested CADR ratings.
Note: CADR only represents the efficiency and not the effectiveness of an air purifier. The effectiveness of an air purifier depends on the filter types and quality.

An air purifier is one of the must-have appliances in any establishment you spend more time – be it at home, office, or even your camping van. The CADR rating of the air purifier is just as essential to check as its energy efficiency and compactness. This is so because CADR, to some extent, determines how effective your air purifier will be. It also helps you evaluate your needs. For instance, although you might want the cheapest air purifier in the market to purify your large-sized sitting, you’d have to opt for an expensive alternative because it has a higher CADR rating.
