    Works great! Looks very slim too. Easy to use and so far I have noticed that it will notify us when there is smoke in the house when we cook or burn a candle.

    Purchased for a great deal with pricematch. Effective for the price that I paid. Not sure I would pay full price as the air cycles are less than Blue Air or Coway products but when paying 1/4 the price I can’t complain. So far so good. Removes kitchen odors and the air quality in our great room subjectively seems crisper.

    Purchased for home after my neighborhood was impacted by wildfires, although the impact to my home was minimal. Noticeable improvement in air quality and I also appreciate the peace of mind.

    It works as it should. I use it in my apartment and it does make a difference. I live in front of a busy street and the Air purifier not only cleans the air it also absorbs odors.

    I have severe allergies and I was experiencing reactions to various allergens including second hand smoke from the nieghbor upstairs. This air purifier covers 1000 square feet and my apartment is about 850 square feet. When I turned it on, my air qualty was about 65% which was poor. Within 45 minutes, it was at 100%. The air circulates and actually keeps my apartment cooler with less use of my AC. Totally recommend this air purifier.

    I’ve had this purifier for a few days now. I must say, it’s got a simple control setup, makes the air in the home fresh and is not that loud even on its highest setting imo.

    Excellent air purifier. It picks up pretty much any changes in the air. Even with it being in the master bedroom across the house, it will go active, if it picks up cooking odors from the kitchen. I do have to turn it off at night, because I run an essential oils diffuser in my bedroom, and that will send the air purifier into overdrive. VOCs are VOCs, regardless if they are the kind that are good for you or the kind that are bad for you, so that explains it trying to eliminate the essential oils from the air. It just shows me how sensitive the air purifier is. I knocked off a star, only because the filter doesn't seem to last long. It is now roughly 9 months old, and it is already signaling that it needs a new filter. They are kind of pricey and sometimes hard to get, so I'm not looking forward to that purchase. But, it is a very effective air purifier.

    Overall I love it. Bit spendy, but it does everything I'd ever expect an air purifier to do. One caveat--I haven't researched replacement filter prices yet so I'm not sure what those cost. Pros: -Very quiet at the lowest fan speed -Auto setting works well, spinning up the fan speed based on particulate level of the air -Appearance, it looks nice but unobtrusive -Countdown for remaining filter life. Not sure how this is calculated though. Cons: -It'd be great to have an adjustable program for the auto setting. Sometimes I disagree with what speed the fan should be at or how quickly it reacts.

    Very quiet and does a great job at purifying the air in our house. We notice the air quality goes down on days when pollen is high and this does the job.
