What is a good CADR?

The CADR scale goes up to 400-450 depending on the particle size measured. Dust CADR can be as high as 400 and the pollen CADR and smoke CADR can be as high as 450. The CADR gives a relative performance indication. It is mainly used to determine room size coverage of the air purifier.

What is a good clean air delivery rate?

Clean Air Delivery Rate (CADR) was established as a performance metric for the newly created standard. Clean Air Delivery Rate indicates an air filter’s effectiveness in reducing smoke, dust and pollen particles. The comparison is done for particles between the range of 0.10 and 11 micron.

Is Cadr the same as cfm?

The CADR is basically a reflection of the air flow (CFM) times the efficiency of the air filter. So, if an air filter has 200 cfm and 100% efficiency the CADR would be 200. If the air filter has 200 cfm and 75% efficiency the CADR would be 150.

How is Cadr calculated?

To find out the required Tobacco Smoke CADR, divided your room area (sq ft) by 1.55. For example, if you have a 15 ft x 20 ft room (8 ft ceiling), then the area is 300 sq ft. So, the required Tobacco Smoke CADR is 300 / 1.55 = 194 cfm.

What is a true HEPA filter?

True HEPA filter, with HEPA stands for High Efficiency Particulate Arresting, or High Efficiency Particulate Air, is the highest standard for physical air filtration being used by the air purifiers. Moreover, the HEPA filters are applied in many applications, like vacuum cleaners, automobiles and even aircraft.

What is CADR in air purifier?

Clean Air Delivery RateClean Air Delivery Rate (CADR) is a figure of merit that is the cubic feet per minute (CFM) of air that has had all the particles of a given size distribution removed.

What does a HEPA filter do?

HEPA stands for high-efficiency particulate air. A HEPA filter is a type of mechanical air filter; it works by forcing air through a fine mesh that traps harmful particles such as pollen, pet dander, dust mites, and tobacco smoke. You can find HEPA filters in most air purifiers.

What is the highest CADR rating?

450In each category, the CADR rating measures how many cubic feet of air a given air purifier effectively removes each type of particle from each minute. The highest possible rating scores are 450 for smoke and pollen, while 400 is the highest score for dust.
