Easy & Effective
This product has been great so far! It is extremely quiet. Honestly I don’t think it makes any noise. It is easy to take apart and wash. The night light has 2 settings and it’s a the perfect amount of soft warm light. The light kind of looks like a lava lamp when turned on and that makes it soothing and fun to look at. I have this in my living room and it has upped the humidity. I bought a brita pitcher and I use filtered tap water. This humidifier is effective and adjustable. It also doesn’t leave a film or any residue like other humidifiers. I am really impressed.

Excellent product
So far, so good. I run a space heater in my master bedroom, which is large with high vaulted ceilings. After a couple of months, my skin and hair became extremely dry, but the worst part was my hands. They looked and felt chalky — it was awful. I bought this humidifier, and let me tell you, within 3 days I had complete symptom resolution. I was honestly shocked. So yes — it works amazingly well. It also looks great in my room, and I barely hear it running. You can definitely trust the auto sensor feature. I’ve only had to fill the tank once since buying it about a week ago. This is one of those purchases I made that I don’t second-guess at all. It’s an excellent humidifier. One more thing: I placed it on top of my tall wooden nightstand/bookcase, and there has been zero condensation or moisture damage around it.

This works and is very quiet
The easiest set up ever. This humidifier is so easy to use and the fill tank fits under the faucet. The control panel is very user friendly, water flows into the air immediately when you turn it on. And it is so quiet! I did pair it with the app for timer and light control and it couldn’t be simpler. If you don’t want to use the app you can change the light and timer settings right on the control panel. It is efficient adding humidity into my very dry Arizona air. I am very happy with this purchase and recommend it!

Excellent Quality & Effectiveness
The “LEVOIT Classic300S Ultrasonic Smart Top Fill Humidifier worked very well for me. This’s is the first and only humidifier I’ve owned. It is exactly as pictured on Amazon, and functions well. It’s a quality product - performance and durability. I used it nearly 24/7 for two and half years. I opted for a large tank which turned out to be a good decision. The larger the tank, the less often it needs to be filled. Though I was overzealous in hoping it could humidify a very large open-concept living room and kitchen. It did pretty well considering I was trying to accommodate a larger area than it was meant to cover. I regularly used all three mist “output” options to adjust for how the weather impacted the amount of humidity I needed. The vent for the mist can rotate which I found very convenient. The light had just the right amount of illumination. The scent infuser is the only thing I didn’t use, due to allergies not the product. The water container is very easy to clean. Since I wasn’t used to having a humidifier I often forgot to clean the inside the base of the humidifier (where the water runs through the system). That led to a challenge. There were some tiny spaces that needed cleaning but couldn’t be reached by anything I tried - sponge, finger, mini scrub brush, toothbrush, tiny bottle brush. I think it was just the structural design that impacted the reachability of those area. (That might be true for most humidifiers. I don’t know since this was my first one.) Eventually those tiny areas inside the base developed a nasty build up. Ultimately I had to throw it out because it wasn’t healthy to continue using it. That was the only down side of this product. Because I wasn’t diligent in cleaning it sooner and more frequently, perhaps the cleaning issue could have been avoided. If I knew a way to reach those spaces, it would be the perfect humidifier and i would definitely buy it again. Overall it’s an excellent humidifier and very effective in its purpose. Based on this singular experience, I consider Levoit a quality brand, tried and true, and wouldn’t hesitate to buy their products.

Excellent Humidifier – Quiet, Effective & Perfect for Better Breathing
I purchased this humidifier to help improve my elderly dog’s breathing, and it has made a noticeable difference. Since using it, his nighttime coughing has reduced significantly, and he’s now sleeping comfortably through the night. It’s been wonderful to see such a positive improvement. One of my favourite features is the built-in humidity gauge, which makes it easy to monitor and maintain the ideal humidity level in the room. The soft night light is also a lovely touch, providing just enough light without being disruptive. Best of all, this humidifier is virtually silent. It runs so quietly that it doesn’t disturb our sleep at all, making it ideal for bedrooms, nurseries, or anyone looking for a quiet humidifier.

Great humidifier!!
This unit works great and it is so quiet. I run it overnight every month or so to keep the humidity up. My sinuses and throat appreciate it😊

Your happiness is guaranteed
I bought this humidifier in January, 2023. It was everything you would expect of a humidifier - it is super quiet - it puts out a lot of moisture - it doesn't' deposit moisture on nearby furniture - the app is easy to program - you can schedule any function from the app. That is, until the unit won't work after a power outage. So why the 5-star review of a unit that unexpected dies after a total of maybe 9 months of usage over a 3 year period? I didn't purchase the 3-year extended warranty, so the best I could hope for was getting help for some magical sequence of button pushes that would reset everything. I contacted Levoit and they quickly responded and after reviewing a short video I provided of the unit not working, they suggested an additional way of resetting the electronics beyond what is described in the user manual. That didn't work, but still I am happy. Why? After trying all know ways to reset the unit, I notified Levoit that the unit was dead, and they offered to send me a brand new replacement. How's that for customer service! Here is what Rufus says about the warranty: "The LEVOIT Classic 300S Humidifier comes with a Satisfaction Guaranteed warranty. If your product is defective, LEVOIT's California-based Customer Support Team will send you a replacement right away without requiring you to ship it back. For additional coverage, you can purchase an extended warranty through Amazon to extend protection up to 3 years if you'd like extra peace of mind." They take "Satisfaction Guaranteed" seriously. Warranty expired. No extended warranty. Customer not thrilled that unit cannot survive a power outage. New unit on the way. That, boys and girls, is how you crush the competition and win customers for life.

LOVE Humidifier, only wish it covered more area
This is one of my FAVORITE purchases, I have two currently. It is January, I bought one in middle of November, then bought another in end of November and they are both still working. I live in the Midwest, St. Louis, MO, and I am assuming the air here is pretty dry around winter based on the readings on the humidifiers. This is a review on 6L that connects to phone apps. One humidifier does not raise my classroom humidity beyond about 24-30% max. There has been one day out of the last three months that I've been able to raise it to about 40-50%. But, also keep in mind that my classroom uses a window air conditioner (brings in air from outside), and I need too keep my windows open many times to combat the two large radiators in the room that make the classroom feel like it's over 90 degrees and cannot be turned off by the teacher/classroom. The door to my room remains shut during classes. The building might also just be super dry. I close the windows and door at night and turn off the air conditioner to see if that would help trap in the humidity and help the humidifier, yet it still floats from 24-26% in evenings (but I LOVE that I can track it from home from my app, even when not in the same WiFi as the humidifier!). So I do have to fill the tank quite frequently throughout the day and usually have to restart with low humidity on Monday since it empties after almost a day or less of continuous work. I bought a second humidifier, meant to help with the first one in the classroom but it ended up staying in my bedroom. I might try moving it to the classroom eventually or buy a third. In my bedroom, it floats between 30-40% humidity. When I brought home the school humidifier during winter break, I used two in my bedroom and the room easily got to 50-55% humidity with much less water refillings. Since going back to one humidifier in the bedroom, I usually need to add water daily as well and it tries its best to get to 40-45%. Once again, St. Louis air might just be really dry now, although I believe my house is much less dry than the school and much more insulated with air vents in the house and no window AC units pulling in outside air. It is still a super strong humidifier, I LOVE looking at the app for updates on levels (it's like a game for me), but I don't think it's meant for like HUGE areas like other reviewers mentioned (and I didn't expect it to be). My bedroom is not as small as a dorm room, but not a huge bedroom either, my classroom is a good space but not as big as other music classrooms at other schools (it used to be the teacher's lounge). I think a dorm room would be the perfect size for this! My kitchen at home was also able to stay at a good consistent 45% humidity pretty fast when trying it there for an hour or two (with no doors separating the kitchen from the rest of the house). I didn't expect/want to buy more than one but I do love the product and it does work really well and none have broken yet. Plus, I haven't gotten seriously sick since using them, and my throat is thanking me for the slight relief in dryness during the school day. It really is paying for itself so far, I will try my best to update my review if they ever break like other reviewers mentioned. I might consider buying a third if the price ever goes down, although it just raised and I'm not yet sure if adding another humidifier will help or just make me need to do more canteen runs between the water fountain and humidifier to fill it up. So I cannot validate spending more on my classroom for it just yet, but we'll see since I'm already thinking about it again!

Excellent produit, mesure fiable et utilisation pratique
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!!
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!
