I got the purifying tower fan and there's a little rattling sound coming from it, i actually exchanged my original one at the store because it started rattling after a day... this one started after about 10min, it comes and goes and is not very loud as a matter of fact i cant hear it if the tv is on, and it doesn't get louder when i turn it up…
It literally sounds like the fan it lightly hitting something or is slightly off balance or th3 bearings are loose or something....
Are these supposed o do this
