Review: Great product, works immediately - Wow - my sleep quality went from a 2 to a 10 in my house! I wasn’t sure why my sleep was so awful and it seems new heater devices in house just fried-dried up my house. I thought it was just typical wintertime but nope- this humidifier took my rooms from 29% to 57% and I couldn’t be happier in may 30?minutes tops! . The device shows you the humidity levels, gives you cool or warm mist and three levels too. Super easy to use and clean. The sound isn’t bad but the higher the mist level the more sound you hear so I put it in low overnight. To be able to breathe fully is priceless! The thing stays lit but I just face it backward at night. I’ve run this almost continuously 24/7 since I received it and I’ve had zero issues. One of the best buys I’ve made from desertcart.
Review: Best room humifier with automatic mode - Love this humidifier. It works great. Top fill is the way to go. Less chance of leaks and easy to fill. The auto mode is very nice it adjusts as needed, warm or cool. Very easy to use. Works great. Definitely recommend getting the extra pads and filters. They keep unit cleaner. I like that I can use functions without the app. Highly recommend this unit for smaller rooms. I have this unit and the LV600S which I highly recommend also. I like the lv600s better for you can adjust the humidity % and its larger tank, and the fill area.

## Questions & Answers

**Q: Does this use a filter?**
A: yes, the Levoit Classic 300 (LEVOIT 60-Hour Top Fill Humidifiers for Bedroom Large Room (6L)) uses a filter. The product comes with one filter installed and one extra plus a small cleaning brush. Levoit recommends using their replacement filters.

**Q: Does this unit make a water gurgling noise or loud dripping noise?**
A: I have tried several different ultrasonic humidifiers, and ALL of them have made a persistent, water-dripping, coffee-percolator sound, this one included. When this is on the lowest setting, it's quiet; any other setting, including sleep mode, sounds like a loud coffee percolator running nonstop. Impossible to sleep with it.

**Q: I'm thinking of getting an air purifier also from Levoit, is it okay to put this near one?**
A: Please keep in mind that the design of a humidifier is to increase the water particles (humidity) in the air and an air purifier's design is to remove any airborne particles in the air. Trapped water particles may cause the filter to saturate quicker and possibly harbor mold/mildew buildup. If you would like to keep the two in the same room, we recommend running the two at different times as far away as possible.

**Q: "sleep mode .... uses a built-in humidity sensor to automatically maintain a comfortable humidity level"  What is the exact humidity level?  %**
A: Hi, the intelligent sleep mode turns off all display lights and uses a humidity sensor to automatically adjust the mist level to maintain a 60% relative humidity (RH) while you sleep.

### ⭐⭐⭐⭐⭐ Love the humidifier, plenty of details to share
*by J***. on March 5, 2026*

The noise level on this humidifier is so incredibly low that I barely know it’s on. Actually, I don’t know that it is on unless I look for the mist. Other than working reliably, having a quiet humidifier is important to me because I am incredibly noise sensitive. Even in a very quiet room, I don’t notice that’s this humidifier is on. Other features that are important to me: it is very sturdy and and yet lightweight. Easy to carry from them to room, very portable, and there are no leaks when the tank is full. I particularly like the sleep mode so I can sleep through the night without any light at all. This humidifier was the ONLY thing that made me comfortable when I had a very bad cold, with symptoms as bad as the flu. This cold was a beast and I was down for a week. Nothing relieved the total stuffiness in my nose except for this humidifier. Not nose sprays, not over-the-counter medication,nothing. But all I had to do was fill the tank on the humidifier then turn it on and…relief. I won’t say I had instant relief but within hours I did. Also, the heat level is high enough to be effective and yet low enough that I could lean over the mist to loosen the mucus in my nose and relieve the stuffiness.
