This air purifier works exactly as advertised. It effectively improves air quality, and the difference is noticeable. The companion app is a great bonus—it makes it easy to control settings remotely and monitor air quality in real time. Setup was simple, and it runs quietly, even on higher settings. Overall, a reliable and convenient air purifier that does its job well!

This air purifier rips!! With a bunny running around it was getting dusty an fur was everywhere. I keep it on auto sensing all day and have yet to sneeze after getting the core 400! Works fantasticly well, even cuts down general dust build up. On auto you can't hear it at all. Love the sensory capability an how it actually recognizes air quality. Even if I cook breakfast it automatically increases speed. You'll be amazed how well this perfoms. Well worth it

I bought two and, so far, I am extremely happy with my purchases. I have one in my livingroom and one in my children's room. They're whisper quiet, very nice and sturdy. Easy to set up and connect to with an app and to my existing Alexa units. The app is easy and simple to use with built in settings for auto off and on so you don't need to program a long tedious schedule of off times and on times.I noticed a measurable difference with the 24 hours I've had them. My house smells fresher and cleaner. I returned home from a quick errand and the house didn't smell. (You know it's bad if you smell your own house.)Prior to receiving them, I did a thorough dusting, vacuuming and shampooed the carpets. My house was long overdue for a deep clean. I and my family were waking up with headaches, coughing, sneezing, just overall feeling unwell for what seems like years. Falling asleep was difficult due to an indescribable uncomfort too.I had the idea it is probably the dust build up, as one night I finally had a clearing of my sinuses and I smelled old dusty dust really thick. And I'm not one to dust often which is not good but lesson learned.I live in a 100 year old craftsman house on a gravel driveway on a very busy countryside road. We have a dog and 2 cats and they are about 70/30 indoor outdoor pets respectively. It gets dusty and grimey and there are so many places for that dust creep in and settle. We also have wildfires in our area that become so thick with unhealthy levels of smoke and particles.I'm beyond happy and comforted knowing I have these quality machines to help keep our home clean, fresh a most important healthy.I will update as time passes. But so far km loving these air purifiers.

Due to living by a fairly busy road, by farmland, and having an oil furnace, our house gets very dusty. To the point where you can sit in a chair on a sunny day and just see dust floating through the sun beams. After years of trying other purifiers that just didn't seem to work, I finally broke down and researched a better one for a change. One article a read listed this one, and after reading through reviews I thought I'd give it a shot.Overall, this purifier was a good value for the money. We keep ours on auto mode most of the time, and it definitely adjusts based on air quality. We have the unit in our living room which is open into the kitchen. When we're cooking, even if there isn't smoke, the number climbs (second picture), sometimes into the 200's and the color is red. Which makes sense due to the burn off of unseen smoke and particulate into the air. The purifier adjusts speed on auto setting, and starts working to knock the number down and get air quality back to normal within a few minutes of being done cooking. Even when the unit is running on "high" fan speed, it's not really loud. As I said, we use ours in the living room but I don't think it would cause much noise in a bedroom either.As far as the size, it's not overly intrusive and is easy to find space for. You just need to make sure you account for the clearance it needs for air. It's also built well for what it is, and doesn't "feel" cheap.Overall performance - we haven't had to dust near as much, as this purifier noticeably cuts down on the dust. It's a performance you can "see", and that's why I'd recommend this air purifier for the cost.EDIT: Added a picture of the filter at cleaning; I cleaned half and left half to show the contrast. Glad this thing is sucking up all that dust instead of our lungs, or having it sit everywhere else on shelves and hard to reach places!

This air purifier is quite sizable and seems to do an ok job at filtering out dust in my room. I have noticed less dust accumulation around but there is still some. The smart features are super conveinient and are a must have in my opinion, and I was able to easily connect this with Alexa for voice control.The only gripe I have is that it is not as quiet as I was hoping; at the lowest setting, the purifier still emits a 43 db sound, which is sort of like a quiet hum. I still can sleep with it on without too much issue, but it wasn't as silent as I was expecting it to be. My standards might be high though since I was expecting the device to be almost noiseless.Regardless however I found this to be a ton quieter than other purifiers I have bought in the past, hence why I continue to use it to make the air in my room a bit cleaner.
