Hunter 30836 4 in 1 Small Room Air Purifier Customer Review

We bought this to aid in the bedroom, save for it's unsuitable because of the noise it makes. It emits a fan-speed-dependent howl that is very irritating as you are tiresome to take a nap.I did an inspection, thinking it force be a bad bearing, save for that does not grow to be the case. With the motor turning below power, the noise is bestow. With the motor coasting down, release the expected "white noise" is produced. It seems be fond of a motor top conundrum.The unit uses an induction motor (the constant sort of motor used in loud vacuums). Release-phase induction motors are notorious for this sort of noise if they are poorly designed.We did not aid the unit save for for one nighttime, so can't display for guaranteed if it cleans air adequately. It uses a typical "99.9%", 0.3 micron filter -- plus a UV light and a so-called "oxygenating catalyst" -- so it should clean about the constant as the typical top.Do not approve of this to aid somewhere that calm down or just pleasant "white noise" is desired. The motor noise is very grating to the ear.
