Ok so it has 4 speeds in low speed it is not noticable to the ear and the purifier will be in this mode most of the time unless the air is really contaminated while it being on auto mode. Sound can be notice when full speed it will be less than an window a/c on low speed.
Sorry, there was a problem. Please try again later.This is not loud at all when the Air quality is at 100% (in Auto mode) but if it detects bad air then it'll go to high power circulation which is noticeable but very silent overall.
Sorry, there was a problem. Please try again later.It depends on the fan speed. I have mine on auto and the fan stays at the lowest setting 99% of the time and you can barely hear it. When the fans are ramped all the way up, it is loud but not too loud to disrupt a conversation.
Sorry, there was a problem. Please try again later.Not loud at all, can watch TV and barely noticed it was running. It can get a little loud on max, yet not annoyingly loud.
