How to Choose CADR for an Air Purifier OEM Project
A practical guide for brands and distributors selecting air purifier models for different room sizes.
Start with room size and use case
CADR is one of the most important selection signals for portable air cleaners. For OEM projects, buyers should define the target room size, expected usage, noise preference and price range before comparing models.
Do not use room coverage without support
Room coverage claims should be tied to CADR, fan speed and test basis. If your target market includes large rooms, offices or hotels, prepare model-level CADR and noise information early.
What to tell the supplier
Share target country, room size, quantity, filter preference, desired functions and certification needs. This helps the factory recommend a realistic product platform.
