Vremi Premium True HEPA Air Purifier for Large Rooms - Removes 99.97% of Airborne Particles with H13, Activated Carbon and 3-Stage Filtration - Have A Great Air Day

I have purchased a number of different air purifiers over the years and this is by far the best. I have had this machine for 2 months and love it so much I purchased 3 more for myself and family.Filter replacement: The best part is the replacement filters are relatively inexpensive. Recently they were on sale 2 for $30 on amazon. I have air machines with washable filters that require a charcoal pre-filter which runs close to $10 each, every 3 months. Ouch. Other true HEPA filter machines I have use are Honeywell and Levoit. Both replacement filters run between $40 - $60. The filters are super easy to change.Performance: The air quality sensor seems very sensitive and changes color depending on contaminants detected. You can turn the indicator light off. When in auto mode, it detects issues, changes color and ramps up the speed. Someone smoking in an adjacent room eventually started a change in color as well as a smoking candle. Once it clears the area, the light goes back to blue and there is a noticeable improvement in smell.Size: It is truly compact and lightweight. Easy to move. The circular design allows more surface area. It is shorter than other machines (16 inches tall) and can sit on the floor or a table. I think its attractive.Lights: There is an air quality indicator that can be turned off, which is great if you don’t like additional lights on at night. One of my relatives likes that the light can serve as a nightlight. When the light is on, you can clearly see the quality indicator light (blue, green, amber, or red) from across the room. It has a nightlight. As best I can tell, if the air machine is off, you can turn on a night light that is amber. This is weird because amber is also the color of poor air if the machine is running.Noise: In auto mode is quiet unless it has detected an issue. Has sleep mode which is barely audible.Two months in, I hope if continues to be a great performing machine.

Product works great! Air smelled cleaner after just a few minutes. I live in a 320sqft apt but I'm certain this would work well for bigger places too. Bought it for cat dander, dust, and asthma problems, and it seems to be helping quite a lot already.It's bigger than I thought it would be but still fits nicely on a table. Nice and quiet too. It's super easy to use and has a well-written instruction manual. The digital menu on the purifier itself is super easy to figure out (every button is labeled) and has a ton of useful features (timer, auto-mode, sleep mode, etc). I do wish it had a child lock for the buttons (mostly because my cats keep turning it on/off) but that's a very small complaint. I'm very happy with it.Customer service is also fantastic. I've never had such a good experience with a third-party seller. My original package was suspected stolen (it wasn't placed into our package locker and I live in downtown Seattle...) and I was concerned I wouldn't be able to get help, but they got back to me within a day and sent me a new unit, no questions asked. It arrived less than two days later!tl;dr Awesome purifier, especially for the affordable price. Excellent customer service in case you have problems. Buy it. 👍

If you are familiar with air cleaners, then skip to the next paragraph. This is a wonderfully useful appliance that helps clean the high ppm pollution, bringing it down to a breathable, non-carcinogenic level. Breathing smoke is terrible. I usually place this near the kitchen when someone cooks, and transportation there is easy. I suspect that unless you are significantly physically impaired that you too can move it. This unit uses a round filter that must be replaced approximately biannually with regular use, a cost of around $30 anually to maintain. I find that cost worthwhile. It will keep a neutral smell in the placed location and is efficient for my living room that is connected to the dining room.This filter device has two hallmarks that make it stand out from others that I have used. 1) The most important is that it has a detection mode. You can leave it on auto, and it will detect the ppm pollution and change fan speed accordingly. This feature is color-coordinated according to the detected severity (red, orange, green, and then blue, from worst to cleanest). 2) It has a sleep timer that is useful for wanting the device to clean a smell or pollution, but you don't want to run it all day.The only con is that I would not say it is the quietest thing ever. I gave it a 4 of 5 in that area (so it's not horrible). It does create white noise that is enough to dampen sound (think of a slightly louder Dohm). To that effect, it may be able to pull double duty if you want white noise.
