Clean Air Delivery Rate (CADR) Testing

WHAT IS CLEAN AIR DELIVERY RATE (CADR) TESTING?

Clean Air Delivery Rate (CADR) Testing is to measure the efficiency of a device (air purifier) to produce clean air for a room. CADR will measure the cubic feet per minute (CFM) of air that has had all the particles of a given size distribution removed. A higher CADR a device possesses indicate its greater ability to return clean air to the room. CADR value of a device will assist consumer on making decision during purchase of the device. 

As contaminants can be generated by people, processes, raw materials, facilities and equipment, it is important to continually review the level of contamination and prevent contaminants from entering the cleanroom environment.

TÜV SÜD PSB is able to help air purifier manufacturer to determine the CADR of their product, which assist manufacturer to get their product access to market, and continuous in product improvement.

WHAT IS CLEAN AIR DELIVERY RATE (CADR) TESTING?

TÜV SÜD PSB utilises internationally recognized ISO 14644 standard for cleanroom testing. The standard describes the methodology for a system to assess and control biocontamination in cleanrooms and associated controlled environments with various risk management and control.
