Quiet and seems to work great

Our interest in this product is to place near the PC at the end of our living room. There is considerable more dust attracted to that area for various reasons. 1. Several electronics there (Alexa / Google Home / land phone / PC / TV / lamps / etc. 2. Much move activity in that area. 3. Furnace vent I've learned (yes - had this happen) that dust, over time, can / did build up in the CD drive of the PC tower and cause many burned CD's to skip. Yes, I keep it cleaned with one of those CD disc cleaners, so I thought for a long time it must be defective CD's, BUT NO = just DUSTY. It's incredible how much dust collects around electronics. SO, I'm counting on this unit to help keep the air clear in that space, not only for me but electronic equipment that I count on. SO FAR it's done a good job. This SMALL unit couldn't be any easier to operate. There's three touch buttons on top 1. On / off 2. Fan - touch for three levels of speed. >>> Low - almost no sound >>> Med - about the volume of a refrigerator running. >>> High - soft / about twice the volume of refrigerator running Has these same volumes whether the Ionizer switch (under the top piece) is turned on or off. Depending on the speed - one can feel some air movement around the unit, and mostly, several feet above it (6 - 8 ft) 3. Timer - for 2 / 4 / 8 hrs. 4. Night Mode - see manual. The unit is 15" T - 8" W - approx 6 ft power cord. To ACCESS the FILTERS - UN-screw top off with counter clockwise turn There's a washable 'bag filter'. An indicator light by the power button comes on when the main filter needs replaced, which is 10 inches tall - 6 3/4 inches diameter. This has been an efficient - helpful - good running unit.

This NOMA Small Air Purifier with True HEPA Filter is in my son's bedroom. He's glad to have it. The sound level is minimal to the point that he forgets about it. He does feel like the room is more comfortable since he's put it to use. He likes it enough that he's actually keeping track of keeping the pre-filter clean. It is a reasonable size for a bedroom in that it is big enough to have an impact but not so big as to take over the room. It looks nice too so it isn't an eyesore. All in all, we are quite pleased with it.

Im so happy with this air purifier! It has a HEPA filter, and its very low-profile the perfect size for a small room (bedroom, bathroom, etc.). Its also incredibly quiet on the lowest setting. On higher settings, it emits a white noise that isnt bothersome to me or my partner. Do note that this air purifier doesnt automatically detect anything, so you need to change the settings manually as needed/desired.
