When looking for an air purifier, one of the metrics you must consider is the unit’s CADR rating. An air purifier is only as efficient as its CADR ratings – the higher the scores, the bigger space your air purifier will be capable of cleaning. Also, higher CADR means faster cleaning in smaller rooms.
This post discusses the CADR ratings and the 7 best high CADR air purifiers, including their top features, pros, and cons.

Table could not be displayed.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
CADR (Clean Air Delivery Rate) is the amount of air purified by an air purifier at a given time. It is usually expressed in cubic feet per minute (cfm) or cubic meter per hour (m³/h).
Like the horsepower of a car, CADR is the unit of measurement of an air purifier’s cleaning power. You can easily calculate the effective room size from the CADR ratings and vice versa.
Calculate the required CADR for your room.
AHAM verified CADR
AHAM (Association of Home Appliances Manufacturers) developed a standard (ANSI/AHAM Standard AC-1) for CADR ratings. They verify the capabilities of air purifiers against three types of pollutants. Tobacco Smoke CADR is for tiny particles, Dust CADR is for medium particles, and Pollen CADR for coarse particles.
Reminder: Normally, the CADR only represents the efficiency of the air delivery and not the effectiveness. The effectiveness of an air purifier depends on the types of air filters.
