  • Worth the money!
Set name: 6L Smart Grey
I have purchased COUNTLESS different humidifies over the years. In the end I never really liked the ones I purchased and would only end up using them for a short amount of time. This one is very well made, the parts are sturdy not like some of the cheap plastic ones I had purchased previously. It is very user friendly, you can fill it up and turn it on and get it going right away. I feel the tank capacity is good sized for your average sized bedroom. I love that it has a display for the humidity instead of having to try and guess what the humidity of the room may be at. It is also quiet which is a huge plus for me as I don't like hearing the loud noise in my bedroom. It has a light function which I don't use as I prefer it dark in the room, but some people may enjoy that feature. I also found it easy to take apart and clean which is always a plus. I have noticed a huge improvement in the humidity level of the room since having purchased this. It is an absolute MUST in the dry cold winter to have something like this it has helped my sinuses a great deal. ... show more

  • Life saver
Set name: 6L Smart Grey
I cannot recommend this LEVOIT humidifier enough, and it easily earns 5 stars from us. It is incredibly quiet and highly effective, providing the perfect amount of moisture to the air without making any disruptive noise. Nightlight in 2 brightness settings neither is disruptive. Full refill capacity easy to fill and clean, used for 4 nights on auto setting When our child was diagnosed with pneumonia, this machine truly gave us our sleep back by easing their congestion and letting them rest comfortably through the night. It is a fantastic, reliable product that delivered exactly when we needed it most. ... show more

  • Excellent product
Set name: 6L Smart Grey
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. ... show more

  • Excellent Quality & Effectiveness Excellent Quality & Effectiveness
Set name: 6L Smart Blue
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. ... show more

  • Your happiness is guaranteed
Set name: 6L Smart Grey
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. ... show more

  • Still excellent after 3 years — reliable and smart features
Set name: 6L Smart Grey
I purchased this LEVOIT humidifier about three years ago, and it is still working perfectly with no issues. I always follow the maintenance recommended by the manufacturer, and the unit rewards you with long‑term reliability. The app control is very convenient — it shows humidity levels, schedules, and operation status right on the phone. I regularly check the sponge inside the clear tank and replaced it when the color turns dark brown. Keeping the unit clean is important, and it has been easy to maintain. My only small concern is not knowing exactly when the black ring (where the vapor comes out) should be replaced, but so far it continues to work well. Overall, this is a very good humidifier, and I definitely recommend it. Five stars. ... show more

  • Great little humidifier, easy to clean, quiet
Set name: 6L Smart Grey
As cool mist humidifiers go, this one is easy to clean and operate. One part is a little difficult to remove for cleaning and I have been able to manage. Distilled water is recommended, and you need at least three cups of white vinegar to clean it every three days. I elected not to download the app and have been pleased that the machine works fine without it. The Levoit does a good job moistening the air in my bedroom and it is extremely quiet. Sleep mode shuts down all those annoying LEDs! My only issue with the humidifier is that because the touchpad buttons are flat and don't "give" when you push them, and there are no haptics associated with them, if the unit is in sleep mode (no lights, operating according to humidity level in the room), there is no way to tell if you've successsfully turned it off. I found myself blindly pushing buttons more than once. ... show more

  • Great Humidifier, Great Support
Set name: 6L Smart Grey
The humidifer works great, alot of steps to clean but isn't too bad and its very easy to setup and control. Only issue I have is noise which there is a subtle whistle I hear from the base. At first I thought it was a defect or something broke so I went through support and they helped me get a new one but I also heard the noise from the new one too. I listened to another one from a friend who had the same one but I heard the whistle too so it may just be my ears being more sensitive to higher pitches. ... show more
