Amazing Humidifier
This humidifier has made a noticeable difference for me. The air feels less dry, and my nose and throat feel much more comfortable, especially in the morning. It runs quietly and works well through the night. It’s simple to set up, easy to refill, and doesn’t leak. I like the clean design and how consistent the mist output is. For the price, this has been a great buy and I would definitely recommend it.

Phenomenal Product and Support
I am absolutely thrilled with my new Classic 300S Humidifier! Not only has it made a remarkable difference in the air quality and comfort of the bedroom. In addition, the entire experience, particularly with their customer service, was truly outstanding. 💨 The Humidifier Itself The Classic 300S is solid. It's quiet, has a sleek design that blends seamlessly with the decor, and the top-fill feature makes refilling a breeze. The mist output is impressive, and the automatic shut-off gives me peace of mind. It holds enough water to run all night and often well into the next day without needing attention. It's clear this is a high-quality, durable appliance. 📞 Phenomenal Customer Service What really sets this purchase apart, though, was the phenomenal customer service. The response time was quick, and the care they showed demonstrated a genuine commitment to their customers. In an age where good customer support is rare, their team knocked it out of the park. It truly solidified my trust in the brand. Highly recommend the Classic 300S for anyone needing a reliable, effective, and beautifully designed humidifier. You're not just buying a great product; you're also buying into a company with incredible support!

Buying distilled water can add up but its worth it and I dont' have to clean it often.
Excellent humidifier – I don’t know why I waited so long I absolutely love LEVOIT products, and this humidifier is no exception. I’ve purchased three LEVOIT humidifiers in the past two weeks, and all of them have been working flawlessly. Setup was quick and easy, the top-fill design is very convenient, and cleaning and assembling the unit is straightforward. The app is a big plus—it’s easy to control and gives you more useful information than just basic humidity readings, which I really appreciate. Before using these humidifiers, the humidity in our house was around 25%, which is very dry and unhealthy. Since adding one to our bedroom, I sleep noticeably better, wake up without headaches, and no longer have a dry nose or mouth in the morning. As a bonus, our plants in the basement are loving it too—no more curling leaves, brown edges, or leaves falling off. Overall, I’m extremely happy with this purchase and honestly don’t know why I waited so long. Strongly recommend LEVOIT if you’re looking for a reliable, well-designed humidifier.

Good product to Humidity a single room.
This is my 2nd 300S humidifier. First one stopped working soon after the warranty ran out. Good customer service. Bought an extended Amazon warranty to give us 3 years of protection this time around. It works really good when programming a weekly schedule. I programmed it to operate nightly as we sleep. Gets really dry here in the winter because of the forced air heating. I have an Aprilaire system on my furnace but never worked. Not a fan of all the cleaning required to keep it running properly even with using my Reverse Osmosis water. A nice looking well made humidifier for a single room. Easy setup with app to your WiFi. Little to no noise during operation, a fair price.

This is the BEST Humidifier! WOW What a Difference it Makes.
This humidifier is amazing! I had purchased a seriously flawed evaporative humidifer that I had to return and then I ordered this ultrasonic one. Right out of the box it really gets the job done! It couldn't be easier to set up. Open box, fill up and turn on. I leave it on medium and it runs more than 24 hrs without refilling. It's quiet too even on the regular setting if you choose to use it in the bedroom. Since I use it for allergy relief I asked my new BFF ChatGPT the best way to place it in my living room. I have it set up elevated near to my chair and the humidity level makes all the difference! It humidifies a decent amount of space too. I am a senior and it's not too heavy to fill it in the kitchen sink and carry it back out to the living room. So far I don't see any white dust and I am using tap water even though they recommend the filtered water. I just ordered their demineralization cartridges too just in case. I'm very happy with my purchase. I think you will be too! Just buy this one first and you'll be all set!

VERY functional & easy to use!
Love this humidifier! I have this one in my office at work and it has really helped keep the humidity up for my plants. The size of the tank is great and lasts through the weekend when I’m away as long as it is kept on low or auto. The app makes it really simple to control and tracks the humidity levels over time. I loved it so much that I ended up getting an air purifier and another humidifier to keep at home!!

Best Humidifier and we've tried a lot
Our apartment is always dry in the winter so running humidifiers in each room is essential to keep from having dry skin, bloody noses, and coughs. (it is also beneficial to all my plants!). We have used several different types of humidifiers from several different manufacturers. We have found the Levoit humidifiers to be the best and keeping our rooms above 45% and are easy to use and more importantly, to clean! This particular model is my favorite because it can be controlled from my phone and also has automatic features to control the humidity levels to keep the room at a comfortable level. Cleaning is also easy - We use vinegar, water and dish soap to keep the film that collects inside the tank at bay. We have hard water so often there is a crusty residue in the base. To help with this, we purchase small water filters here on Amazon https://amzn.to/3K1aYWg (shaped like goldfish!) placed inside the tank to filter the water a bit and reduce the nasty film. We also use filtered water from the refrigerator, which I highly recommend! It also looks nice! I like the night light feature too and the fact that this unit is super quiet.

J'ai acheté ce produit notamment pour fournir un meilleur taux d'humidité à mes plantes d'intérieur. Pour le moment, rien à redire, il fonctionne parfaitement. La fonction 'Auto' lui permet de se déclencher dès que le niveau d'humidité passe sous un certain seuil et de s'arrêter de la même manière lorsque celui-ci atteint le niveau fixé. Il est aussi possible d'utiliser l'appareil en mode 'Manuel' en le déclenchant soit même et choisissant un niveau de brumisation. Le remplissage se fait très simplement par le haut et le contrôle via l'application VeSync est un petit plus pratique.

Works great for our living room (8x5m) I also got it to work in home assistant. I bought this model specifically for using it in home assistant and because of the good reviews. +: Big tank, silent, clear display, the cats stay away from it, app works great - : You have to create an account (I read somewhere that a credit card is needed. This is not true!). If the company takes down the service, the home assistant integration stops working. All together a great machine!

Excelente. Tengo varios humidificadores. Este es moderno; fácil de recargar el agua, aun con el aparato en marcha. Manejo a través de la app y Wifi fácil, útil y cómodo. Puede cubrir una superficie tal y como se indica, pero hay que pensar en una ubicación adecuada. El higrómetro incorporado es relativamente fiable. Hay que repetir ajustes en Auto para encontrar punto óptimo de humedad relativa para que corresponda a la humedad en el recinto - disponiendo, claro está, de otros higrómetros para comparar. Muy silencioso. Hay que colocarlo a media altura para facilitar la recarga del agua (una jarra grande es muy adecuada) - el manejo de la tapa es fácil y no es necesario quitar el recipiente del cuerpo principal para rellenarlo bajo el grifo (salvo para la limpieza). Magnífica compra.
