Since turning on this purifier in our home there has been noticeably less dust .both in the air and on accumulating on our glass and wood surfaces. I think this machine is very quiet and beauty. I operate the machine for an hour or two every day .The operation is very simple and easy.cycles through fan speeds: low ,medium,and high. You can also select auto or sleep mode, or act a timer too.the filter is easy to access for chanting.air quality using the automatic sensor ,the air purifier may take up 1 minute to detect air quality.

It’s super quiet everything as described. We put it in AUTO mode. It worked awesome during we cooked. WiFi is a plus when you away from home you can check from your phone or iPad. Unit looked and feel solid. Not cheap material I have been used everyday for last 6 months and zero issues

The air purifier is super quiet, everything as described. I put it in the "auto" mode and the light is blue, which indicates that air quality is good. I set it in my living room and the other day I burned my pork and there was quite a bit of smoke from the oven. The purifier went from blue to green and then to red in a few minutes and it became noisier and it was obvious working. After the smoke cleared, it went back to blue and stayed quiet. I also noticed there was significantly less cat fur on my fireplace counter because our cat loves to hang out there. It definitely works in filtering out smoke, fur and dust. Right now I put it in our master bedroom because our neighbor is under construction. I am a quite light sleeper and I set the unit to "sleep" mode and the air purifier did not disturb my sleeping at all. Very satisfied with it!

I have really bad allergies and our moody Texas weather doesn’t a help. I have lowered my allergie problems after buying this for our bedroom. I plan buying one for every room of the house. The App it comes with a super helpful convenient and cool for over all health needs. The purifier honestly a lifesaver anytime we go on vacation or stay over at family houses,my sinus’sact up resulting in me getting a sinus infection but I hardly ever get them at home now that I have the purifier set up.

I live in metro area which can be really cold in winter. Since the heater in house was turned on in October, I haven't really open with windows therefore when my mom is here she complains about the air almost all the time. Then I got this air purifier. The setup was very easy: take it out of box, remove plastic cover of filters, plug it in, download the app on phone and setup WiFi connection, done. When it was first turned pn the air quality showed bad with red color, a couple of minutes later, it turned yellow and another couple of minutes later it turned green. I left it on for an hour or so. Gotta admit, even for someone who is not sensitive to air quality like me, I noticed the difference. It works very efficiently and I am definitely happy with it.
