CADR Rated Air Purifiers - Improve Your Air Quality

CADR Rated Air Purifiers are devices designed to clean the air in a room by removing contaminants such as dust, pollen, and smoke. The Clean Air Delivery Rate (CADR) measures the volume of filtered air an air purifier delivers, with higher values indicating more effective air cleaning.

What is a CADR rating for air purifier?

This means that the larger the CADR rating of an air purifier, the more efficiently it will clean the air in your home. We can also say that the CADR is the airflow reflectivity (CMF). Basically, if an air purifier has a CFM of 300 and an efficiency of 100%, its CADR would be 300 (this is just an example).

What is a CADR rating?

A CADR rating is a certified measurement that reflects an air purifier’s efficacy. CADR ratings measure the volume of air in CFM (cubic feet per minute) with separate scores for tobacco smoke, pollen, and dust. The purpose of a CADR air purifier rating is to give you an objective standard to evaluate the effectiveness of an air purification device.

What is a high CADR air purifier?

An air purifier with a high CADR rating of 300 for dust will reduce dust particles at a faster rate than a unit with a lower 200 CADR rating. According to the AHAM, “Using an air cleaner with a higher CADR in that room will simply clean the air more often and faster.

What does CADR stand for in air purification?

What Does CADR Stand For? CADR stands for “Clean Air Delivery Rate”. It’s a metric used for measuring how well an air purifier performs. In essence, the higher the rating, the quicker the air is purified. There are a number of categories which each get different ratings such as smoke, pollen and dust.

What are the limitations of a CADR test for air purifiers?

For most residential air purifiers, this test has a high degree of validity. The limitation presented by the size of the testing chamber volume include: Maximum Smoke CADR rating of 450 CFM. Maximum Pollen CADR rating of 450 CFM. Maximum Dust CADR rating of 400 CFM. These limitations only cause problems when testing industrial air purifiers.
