What is the clean air delivery rate (CADR) of air purifiers?
Clean air delivery rate means the amount of air that is measured in cubic feet per minute that an air purifier cleans. The CADR is used to see the performance of the air purifier and is an important factor to see the purifier’s Energy Efficiency. to Check the air purifier’s energy efficiency CADR per watt is used. Air purifiers having higher CADR per watt will be more energy efficient. The clean air delivery rate of an air purifier is between 0.9 to 14.8 CADR/W. An air purifier helps to clean the smoke, dust, and Pollen particles from the air, and for cleaning these particles the CADR/W rate does vary for each.
CADR per Watt for smoke:
- An air purifier does have CADR/W to clean the air ranging from 1.9 to 14.8.
- On average an air purifier cleaning the smoke from the air rate is up to 4.4.
- The most common CADR/W for cleaning the smoke is 2.5.
- The most energy-efficient air purifier for cleaning the smoke from the air is the powermatic PM1250.
CADR per watt for dust:
- An air purifier does have CADR/w to clean the ear from dust particles ranging from 1.05 to 13.6.
- On average, an air purifier has CADR/W for cleaning the dust from the air rates up to 4.44.
- The most common air purifier shows the CADR/W for cleaning the dust is 2.59.
- The most energy-efficient air purifier for cleaning the dust from the air is the powermatic pm1250 and the air purifier with the most energy efficient for households is the Blueair-joys
CADR per Watt for pollen:
- An air purifier CADR/W rate for cleaning the Pollen from the air ranges from 0.9 to 14.71
- An air purifier does the cleaning of pollen from the air is 4.81 CADR/W.
- The most common air purifier for cleaning pollen is 4.07.
- The most energy-efficient air purifier is the powermatic PM1250 which has a CADR/W for cleaning pollen is 14.71.
Which are the most energy-efficient air purifiers?
The most energy-efficient air purifier is the air purifier which removes smoke, dust, and pollen from the air at a good rate. The energy efficiency of an air purifier depends upon the room size also. The following table explains the most energy-efficient air purifier according to the specific room size and the electricity consumption by them. to know the cost to run an air purifier click here.
| Room size | Most energy efficient overall | Electricity consumption per month |
| Less than 100 sq. ft. | BLACK+DECKER – BAPT01 | 6.84 kWh |
| 100-199 sq. ft. | Blueair – Joy S | 4.77 kWh |
