Outstanding Product and Even Better Customer Service
I’ve been using my Levoit air purifier and it has been fantastic. The device works exactly as advertised and the smart app features make it super convenient to use. Recently, the LED screen on my unit malfunctioned. I reached out to Levoit support and I was beyond impressed with how they handled everything. The team went above and beyond providing frequent updates every few days and resolving the issue quickly. In the end, they replaced the entire unit and the process was smooth from start to finish. Excellent product and outstanding customer service. I couldn’t be happier.

Life saver
This product has exceeded my expectations. I was searching for a reliable and efficient air purifier after my spouse developed allergy issues. I had tried another brand before, but it didn’t help at all. After extensive research, I noticed many users recommending Levoit as a dependable alternative to more expensive brands. Since using it, my spouse’s allergy symptoms have improved significantly — truly a life saver.

Very smart and excellent Air purifier
After months of research I got this product...... Initially I tried the blue air 211 plus auto but was not satisfied and replaced it with core 600S and I am very happy now. Pros: It removes odors and its very quiet in the sleep mode and Eco mode. Its not true that its very noisy. In higher speeds its loud as the other competitors. The fan is very powerful and purifies the room faster. Turbo mode is loud because it purifies faster and that its a beast. Best pricing compared to all the air purifiers in the market. Design looks modern and elegant. Smart features are awesome and fun to explore and control. App is perfect. Cons: The touch display on the top is not visible because of the white silver color background. Black color like 400s would have been better. Sometimes I feel the PM2.5 air quality monitor is not very accurate but at this price point its not much to argue with. Filter is not availble easily in UAE. Right now only in Amazon I am able to see and also its being imported. I hope amazon sells it always without showing out of stock. Overall: The best air purifier with lots of smart features and really it does a great job in purifying the air....I would highly recommend this product. It would be good if the filter is avaible in few more places...Kindly expand the Levoit products to India as well.

Perfect piece that cleans the fine dust out of our home
This air purifier is actually one of the best things we have ever bought. We use it in different rooms and you can really breathe the difference, as the air in the UAE is usually very polluted with fine dust. This fine piece of technology is removing 99,99% of it and we can sleep again without nose bleeds and coughing. It is very quiet and still effective. The filter holds for some months. We like the display that is showing you some details. We have another one that doesn't have this functionality and with that one you never know how much polluted the air still is. We can only recommend it and would buy it again.

We purchased one of these on sale in the hope it would help moderate the severity of pollen season in upstate NY and the dander generated by two large labradors. It has a nice, clean look and small foot print, which we feel is important. The HEPA filter was shipped inside it in a bag that needs to be removed but doing so was incredibly quick and easy to do. Twist the top a quarter turn and place to one side. Lift out the filter, remove the bag, lower the filter back in using the two tabs provided on it for that purpose, lift the lid back on and quarter twist to close. It takes 2 mins. Then its' plug-in, turn on and choose ""Auto" or a fan speed using the touch sensitive panel on top. You can control it from your iphone if you're into that but it certainly isn't necessary. The first thing we noticed is how quiet it is. Effectively soundless in sleep mode and at fan speed 1. Barely noticeable at fan speed 2, unless you're right next to it, noticeable at fan speed 3 when you are in the same room as it but not obnoxious. Noticeably louder at fan speed 4 which should be considered a 'Turbo" mode. Then we noticed the impact of running it - vastly reduced swelling of the eyes and sinuses of those suffering from hay fever and a significant reduction in the doggy smell of our labradors. It works really well. We have taken advantage of the ability to control this by iPhone to set a schedule where it automatically runs in sleep mode (low, continuous fan) from 10pm to 5am. Then at fan speed 2 from 5am to 5:30am, ramping up to fan speed 3 from 5:30am to 8am before switching to auto from 8am to 10pm. Because of the relatively severe allergies suffered by a couple of our family members the P2.5 micron threshold is set to 2 ug per meter cubed and this filter has been able to attain that incredibly low level with that schedule within a few hours of all windows and doors to the outside being closed to the 1800 sq. ft area it services. At this point we have an oasis for our hay fever sufferers to return to each evening and it's made an incredible difference to their comfort. Do they still take Claritin or Allegra during pollen season? Yes, we've found it necessary to deal with the pollen at work and in the garden. Are they doing better than they were before we got this filter? Yes, the continuously swollen and itchy, weeping eyes are gone. The inflamed nasal passages are gone. Their sleep deprivation is gone. Their quality of life has improved dramatically. We had no idea how dramatic an impact adding a quality, appropriately sized HEPA filtration system would have. This unit is rated for something like 3000 sq. ft. We're using to control air quality in a 1800 sq.f.t open plan area and its doing a great job of that without having to run the fan at high speed for prolonged periods of time. We've had this for several weeks now and experienced 1st hand how well it can deal with really terrible air quality when the smoke from the fires in Quebec blew into NY. Opening the door to come into the house with the shopping during the worst of it briefly dropped the air quality from a PM2.5 of 001 to as high as a PM2.5 of 185 within 12 feet of the door. This was then quickly reduced to a PM2.5 of less than 20 in an hour and back to 001 in about 2 hours after the door was closed. The outside airs PM2.5 was apparently North of 300 at this time (sources accuweather and the news), the air was literally a hazy brown like smog and this filter was able to detect it, automatically adjust its fan speed to clear it and maintain perfect air quality in the house. Does it work? Absolutely, quietly and brilliantly. Would we buy this again? Yes, in fact we have so that we can control the air quality for one of our allergy sufferers in another area where they have to spend prolonged periods of time. That one's been in place for about 3 weeks and has done exactly what we hoped it would do - improve the quality of life at work in a 7000 sq.ft. open plan office area. Now this is well beyond the manufacturers claimed coverage for a unit and it looks like they're right based on who's apparently benefiting and who isn't but here's the important point. The benefits to the workforce have been so noticeable to management they're now considering upgrading the offices HVAC system to include HEPA filtration. I think that speaks volumes.

Very pleased with my 400 air purifier. The first day of using it our house had lost its locked up winter smell. Watching it automatically increase in speed catching the cooking smells is incredible and it really works. Using it now for a couple of weeks its noticeably helped us with our dust & Spring allergies 👍 Answering some of the negative reviews. Yes the bottom come will come off easily if it hasn’t been LOCKED in place properly and I can hear an electrical hum on auto/ sleep modes at NIGHT, so I leave it on low speed when sleeping. I recommend it and am now looking at buying a smaller one just for our bathroom.

I absolutely love this unit. I heat with wood in the winter, have two dogs, one cat and dust is an ongoing problem. Since having the unit I noticed a significant difference in the indoor air quality. I tried using the timer, which worked quite well, but prefer adjusting the settings on the phone app to accommodate our life activities during the day. At night I set it on high and let it run. Much to my surprise, the filter life is holding up extremely well. After 3 months of use, it states there is 80+ filter life remaining. Even my husband, who complains about everything is satisfied with its efficacy, which is a miracle unto itself. I highly recommend this product. Well worth the money invested.
