Instant HEPA Quiet Air Purifier, From the Makers of Instant Pot with Plasma Ion Technology for Rooms up to 630ft2, removes 99% of Dust, Smoke, Odors, Pollen & Pet Hair, for Bedrooms, Offices, Charcoal

Bought this for my office which is a smaller space but throughout the day and evening, the space doubles as a hang out and warm spot for the smokers in the house to smoke since we don't smoke inside the house and the office is in a finished side of our barn out back. I suppose that makes my office space my Witch Barn (feel free to substitute whatever letter you prefer on the first word lol). The small space fills with smoke rather quickly and tends to continuously have a bar room haze until the door opens or closes. At night, when you open the door you can watch the smoke pour out as if Willie Nelson has been in the room at all long chillin.I was skeptical at first with this because when I initially set it up in my office, the lights were off and it was dark. I thought something was wrong because the unit would come and for a moment and then turn off but the lights were still on. The following day, my husband and I were sitting in my office together working on a project, and he lit a cigarette. Within a few minutes, this little thing lit up red and turned on. That evening, when us and our guests were hanging out, it would pop on whenever anyone was smoking.5 stars because Auto mode is a life saver and the best part? No more bar room haze, no more dusty and musty smells, and it clears the smoke in less then 30 minutes. It's quiet even when its not in night mode with sound equivalent to the med-high setting on a stand up oscillating fan. Hands down best one of the best investments we've made so far and even better, my allergies aren't kicking when I'm in my office anymore. Will defiantly be buying a couple more, the bigger one for our living room and dining room, and a couple small ones for the bedrooms!!

This air purifier works amazingly well. I have a rabbit, and am allergic to the hay (on top of other seasonal allergies) so usually when I wake up in the morning I usually feel congested. On top of that, it has also helped reduce the odor from the rabbit as well.Very easy to use, I leave mine on auto and it works when it needs to. Have not owned it long enough to change the filter out, but maintenance seems pretty easy looking at the video.It seems pretty quiet, I've been working from home and I hardly notice it throughout the day. The high speed its audible, but its more of white noise.Design wise, it does not take up a lot of space which is a huge plus, and the lights on it aren't super bright which on some of my other electronics, have been annoying in the past.All-in-all, definitely a great purchase for me.

I always thought air purifiers were kind of a hoax, but I have two of these now. The first one I put in the kitchen, and whenever something is getting extra toasted it turns on and deals quickly with whatever smoke particles it detects. I bought a second to set up during a dusty home renovation project, and although of course it couldn't catch all the dust floating around, it definitely kicked into overdrive and kept the air more breathable when dusty things were happening. A sizeable fixture, but they're earning their real estate.

I like it so far. It makes almost no noise, and stays on in perpetuity if you let it. I do notice a slight difference in the air quality, as I have sinus issues and its easy for me to notice. Not sure how well it can handle I highly toxic room though. And its not a dust cleaner; its just purifying the air itself from particulates, so keep that in mind.

I kept seeing these air filters on social media. I didn’t like the way the machine looked so I came to Amazon. I found these, which I already had instant pot items already, and decided to give it a try. We have two dogs and a teenager in our home. Our oldest dog is 12 and can’t be bathed too regularly. I have one of these in our living room and one in our son’s room. When I tell you I walk in my house and don’t smell the dog smell… it is the best! It has three settings so when we leave the house we turn them to the highest fan setting and when we are home we have it on the low setting. We don’t ever hear it anymore because it’s so quiet. It also illuminates which you can turn off, so my son’s bedroom isn’t brightly lit when he is sleeping but the air purifier is still working. I have had these for a few months and it has done such a great job. We live in the south and this is the first year I have had some relief from the pollen while inside.

so far i’m pretty impressed with this thing. our house is a new build and seems really dusty- so I bought a couple of these (the large and a smaller one) to tame the dust a little bit. I just set this on ‘auto’ and let it do its thing. it kicks up automatically when I cook bacon, even though it isn’t right in the kitchen. there’s a light under the control panel that stays white when the air is good- it goes yellow/orange and then red when the air quality is bad. the machine goes off when the room is dark, unless you override and set to a specific level.I like the read-out on this larger model - it is usually 99%, but have seen the number go down and then recover. it is super quiet - but when it kicks up to high you can hear it a little, not terribly loud and doesn’t take long to clear the air, so to speak.have only had these for a few days, but so far i’d say it is worth the $$ spent.
