The Clean air delivery rates are measure using processes

An Air Purifier can be useful for allergy sufferers in conditions where the allergy-causing materials (allergen) are on a particle which stays airborne large enough for it to be gathered by the air cleaner.

The China Air purifiers manufacturers itself must be able of two things: moving a volume of air, large enough that a large amount of the particles in the room’s air finally pass through the purifier; and using a filtering mechanism capable of removing the contaminants from the air passing through it.

1. What is the meaning of CADR?

The CADR stands for Clean Air Delivery Rate and is a measure of the quantity of purified air being delivered into the room. It's the best measure of the specific cleaning capacity of an air purifier, as it reflects both the capability of the filter and the volume of air going through the filter. The higher clean air delivery rate is, the more significant the room size that could be efficiently cleaned of airborne particles.

The Clean air delivery rates are measure using processes standardized by the (AHAM) Association of Home Appliance Manufacturers. This lets the capacities of different air purifier to be compared. Be aware that most of the air purifiers applied have more than one blower speed and the promoted clean air delivery rate refers to the maximum speed.
