    Efficient, quiet, long-lasting, easy to find filter. There is a setting to dim ALL of the lights and quiet the motor that is reachable by hitting 1 button. I have two of these to conquer cat dander because of my asthma. They have been very helpful in conjunction with sweeping and vacuuming.

    We’ve got baseboard heating in our home so it gets stuffy and dusty in our house until we reach AC season. This air purifier has made a huge difference for my dust allergies and we’ve noticed an improvement in air quality. I will definitely be getting another one for our bedroom. The smart function is a nice bonus. We purchased this after extensive research and are extremely happy with the device.

    We have been having really bad weather here in Michigan and these has done its job extremely well with keeping particulate counts down. Breathing problems have also lessened while its running as well. Works great in a 2 cat household.

    Excellent product and does the job very well. When it's cleaning the room, the noise can be a little louder. I try to schedule it from the app to clean it at particular times and schedule a night mode when I'm sleeping so I don't get disturbed.

    10/10, the air quality in my area of choice- large living room, does feel better and increased freshness. I do have live in the Midwest, of course I have allergies… this helps! Although the price of the replacement filters are a little steep for this model. Something to take into consideration when buying

    Works great! I replaced an Insignia with this because you can no longer buy filters for them and it’s been great. It turns back on automatically after a power outage.

    Works pretty well so far. I use it in my salon, and it collects a lot of the hair on the filter, so it seems to be working. The air feels cleaner too.

    I bought this Air Purifier for my teen daughter since she had been having allergies and a bit of breathing issues. This item just so happend to pop up on my social media and decided to give it a try. I love that is not noisy at all, and my daughter loved that she can control it with her cellphone and Alexa. She was so excited to wake up feeling better and in her words "I love breathing" lol.
