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.

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.

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!
I also read the reviews before purchase of this item and it was really helpful. It works so fine for me, having 4 pets in a studio, pretty much covers the whole space. I have not turned it off since, and its working brilliantly. Helps with my allergic rhinitis. Good buy!

Ich habe mir den Luftreiniger gekauft, weil ich zu Hause E-Zigarette rauche und nicht ständig lüften möchte - vor allem abends oder im Winter. Nach ein paar Tagen Nutzung kann ich sagen: Genau dafür erfüllt er seinen Zweck sehr gut. Der LEVOIT läuft bei mir fast täglich im Wohnzimmer. Schon nach kurzer Zeit merkt man, dass der Dampf deutlich schneller verschwindet und die Luft frischer wirkt. Gerade auf mittlerer Stufe ist er effektiv, ohne unangenehm laut zu sein. Besuch hat mich sogar schon gefragt, ob ich überhaupt drinnen rauche - das sagt eigentlich alles. Auch Gerüche setzen sich weniger fest als vorher. Ganz ehrlich: Wunder darf man nicht erwarten. Direkt beim Dampfen riecht man es natürlich trotzdem kurz, und wie langlebig Gerät und Filter sind, wird sich erst mit der Zeit zeigen. Der Filterwechsel ist auch kein Schnäppchen, was man einkalkulieren sollte. Bisher macht das Gerät aber einen soliden Eindruck. Empfehlen würde ich ihn vor allem Rauchern, Dampfern und Allergikern, die ihre Raumluft spürbar verbessern wollen, ohne ständig Fenster aufzureißen. Für sehr große, offene Räume oder wenn man absolute Stille erwartet, ist er eher weniger geeignet. Ich bin insgesamt zufrieden - jetzt bleibt nur abzuwarten, wie er sich langfristig schlägt.

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.

Tras un mes de uso intensivo, puedo decir que este purificador se ha vuelto un elemento esencial en mi casa. Vivo en Barcelona, justo delante de una carretera muy concurrida y con obras constantes en la calle. Buscaba una solución para no respirar ese polvillo en suspensión, y este Levoit ha superado mis expectativas. Lo que más destacaría tras probarlo a fondo: 🔹 Capacidad y Cobertura: Lo tengo instalado en el comedor de mi vivienda de 75 metros cuadrados. Me ha sorprendido gratamente su potencia: es capaz de filtrar y renovar el aire de prácticamente toda la casa en pocos minutos sin ningún problema. Para un piso de este tamaño, va sobradísimo. 🔹 Sensibilidad del Sensor: El aparato "te informa" de lo que no ves. En cuanto abro una ventana o entra algo de humo, el sensor detecta que la calidad del aire se degrada y aumenta la potencia automáticamente. Es muy satisfactorio ver cómo limpia el ambiente y elimina olores de forma tan rápida. 🔹 Modo Noche Impecable: Me preocupaba el ruido, pero en el modo noche es prácticamente imperceptible. Se puede dejar funcionando mientras duermes o ves la tele sin que moleste en absoluto, y además permite apagar las luces del panel para que no haya contaminación lumínica. 🔹 App y Control: La conectividad es muy fluida. Poder encenderlo desde el móvil antes de llegar a casa o recibir alertas sobre el estado del filtro y del aire lo hace muy cómodo para el día a día. 🔹 El "Detalle de Realismo": Debes tener en cuenta que, por su potencia, el aparato tiene un tamaño considerable. No es un dispositivo que pase desapercibido en un rincón; necesitas reservarle un espacio despejado para que la entrada y salida de aire sea eficiente. Además, si vives en zona de obras como yo, recomiendo limpiar el pre-filtro exterior con una aspiradora cada dos semanas para que el polvo grueso no lo sature antes de tiempo. Resumen y recomendación: Es una inversión totalmente recomendada para urbanitas que vivan en zonas de mucha polución o construcción. Si tienes un piso de unos 70-80m², este modelo es el equilibrio perfecto entre potencia y silencio.
