CADR stands for Clean Air Delivery Rate, which can be translated into Dutch as “Clean Air Delivery Rate”. It is a metric used to measure the effectiveness of air purifiers. CADR specifically refers to the speed at which an air purifier can remove harmful substances such as dust, pollen and smoke from the air.

CADR is measured in cubic feet per minute (CFM) and indicates how much clean air an air purifier can deliver within a given time period. A higher CADR value means that the air purifier works faster and more efficiently at removing pollutants from the air.

When choosing an air purifier, it is important to pay attention to the CADR value, especially for specific contaminants you want to use the air purifier for. Different air purifiers have different CADR values for dust, pollen and smoke. By comparing CADR values, you can choose an air purifier that suits your specific needs and the size of the room in which you want to use the air purifier.
