What is a good CADR number?

What is a Good CADR Rating? A good CADR rating is equal to at least two-thirds of the room’s area. For example, a room that measures 10 feet by 15 feet has an area of 150 square feet. Therefore, a good CADR rating for an air purifier would be a smoke CADR of at least 100.

What are good CADR ratings?

To achieve the Energy Star designation the air purifier must have a dust CADR rating that is at least 2 times the power on the highest fan speed. So, if the air purifiers draws 100 watts on the high fan speed it must have a dust CADR of at least 200.

Which air purifier has the highest CADR?

Gocheer GH-Monster
List of the 7 Best High CADR Air Purifiers:

2	Medify MA-112 v2.0	560 CFM
3	Blueair Classic 605	500 CFM
4	Blueair Blue Pure 121	400 CFM

Is a higher CADR rating better?

The higher the CADR test numbers, the better the unit’s overall ability to clean indoor air. For example, if an air purifier has a CADR of 388 for tobacco smoke particles, it will reduce smoke particle levels to the same concentration as would be achieved by adding 380 cubic feet of 100% clean air per minute.

How do you read CADR rating?

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. The CADR is a good way to keep from being misled in marketing messages.

What is the CADR of Dyson air purifier?

Dyson lists their CADR as 70. CADR stands for Clean Air Delivery Rate and represents the air flow of clean air from the air purifier. The higher the CADR the larger room size it can clean.

What CADR do I need?

Generally, the CADR of your air purifier should be equal to at least two-thirds of the room’s area. So, for example, a room that is 15 feet by 10 feet has an area of 150 square feet. ⅔ of 150 is 100, so an air cleaner for that room should have a smoke CADR of at least 100.

How important is CADR rating?

Benefits Of CADR The advantage of the CADR rating is that it gives the consumer a way to compare air purifiers that consider both air flow and filter efficiency. 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.

What CADR rating do I need for Covid?

The Environmental Protection Agency also provides a guide to minimum CADR levels for rooms of various sizes in its online “Guide to Air Cleaners in the Home.” For rooms with 8-foot ceilings, it recommends: A CADR of 65 for 100 square feet. A CADR 130 for 200 square feet.

How do you measure CADR?

To find out the required Tobacco Smoke CADR, divided your room area (sq ft) by 1.55 (AHAM’s 2/3 Rule). For example, if you have a 15 ft x 20 ft room (8 ft ceiling), then the room area is 300 sq ft. So, the minimum required Tobacco Smoke CADR is 300 / 1.55 = 194 cfm.

What is a CADR number?

The CADR number indicates volume of filtered air delivered by an air cleaner. The higher the tobacco smoke, pollen and dust numbers, the faster the unit filters the air.

Is CADR misleading?

The CADR analysis method can be misleading to consumers, particularly given that CADR ratings are not generated in auto mode, and that they are inherently linked to the test chamber size. At Dyson we believe that a purifier should clean the whole room.

How does the CADR rating work in your home?

The CADR rating does not factor in noise level. The CADR is not a safety test so it does not measure ozone production, motor reliability or energy usage. The key to having clean air in your home is to ensure the filters are of sufficient quality and there is proper air flow.

Which is the best air purifier CADR or AHAM?

The AHAM spec is accepted by the American National Standards Institute (ANSI). Consumer Reports has embraced the CADR system, and considers scores above 350 excellent and below 100 poor, seldom recommending any purifier with less than 150.

What does Aham clean air delivery rate mean?

The AHAM-certified seal lists a rating for tobacco smoke, pollen, and dust removal, and a rating for room size. Clean 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.
