Are Ultra-Pure air purifiers noisy?
Absolutely not! Because of our quiet fan engineering as well as multiple filtration technologies that dont put all the work on the fan to begin with, all our air purification units run quietly even when operated at high speed. For example, Ultra-Pures 899 and 988 models generate less than 50dB (decibels) even when operated at maximum power. Thats quieter than your average computer fan and only a little more than the noise a refrigerator generates.
