Review: Clean the air and clear your Asthma, Allergies and Sinuses LEVOIT TOP FILL HUMIDIFIER 2.5 L - I love the Levoit Top Fill Humidifier ! It is very quiet all of the time. I run it all day on low with the steam pointed toward my bed and so far, it's not using that much water. You can adjust which way you want the cool mist to exit as well as the speed from like low to high. I don't have any pets, just nasty carpet. I call it nasty, because all carpet is nasty to me. I dislike carpet so much! I don't have a choice, though. I bought the Levoit Air Purifier also and I think the filter is supposed to last around six months, so we shall see. I bought a replacement filter when I bought the purifier and several filters for the humidifier, as well. It looks like I may have to change the Humidifier filter once a week as a week out, it is starting to turn brownish-yellow around the top of it. I don't smoke and do try to keep an extremely clean place, so not sure what the discoloration is. I'm the only one who has ever lived here. I use distilled water but also bought the demineralization kit and extra filters for the humidifier in case I run out of distilled water and have to use tap water. I clean the humidifier every day. It's not hard to do once you do it. I love the modern look and it is built very well. It's really not hard to use at all. I believe it is super effective combined with my also Levoit Air Purifier. I have them on opposite sides of my small bedroom as I couldn't put my humidifier under the smoke alarm. My skin feels much softer and cleaner using the both of them. I could instantly tell a difference in how well I could breathe using the them. As before purchasing them, I couldn't breathe out of my nose at all. The humidity is brutal here. I have been able to get the humidity down to 58, which is something the local meteorologist said couldn't happen in these heatwave temperatures! Ha! I only use GENUINE LEVOIT filters and they're a bit more costly, but I prefer to use the real deal and have less problems/headaches. It can be a bit catchy to find them on desertcart and the generic ones keep popping up; however, I went straight to the Levoit store to get the genuine ones. Blessed to be able to somewhat better control my Asthma and all-season Allergies with the help of these two awesome products! Thank you, desertcart and Levoit! Sorry for combining reviews but I need to do a copy and paste for the humidifier as it will save me time doing it this way.
Review: Bought for Plants, Not People — And They’re Thriving Like Divas - I didn’t buy this for a stuffy‑nosed child or myself. This humidifier is strictly for my pet plants, and they LOVE it. The mist is a fine, gentle cloud, it runs silently, and it shuts itself off like it has good manners. I had one plant that was sentimental to me — and for five years it had exactly one leaf. One. I’m good with plants, so I have no idea what kind of emotional journey this thing was on. Then I added this little humidifier, and suddenly the plant decided it was done being dramatic. It went from one lonely leaf to six big ones, plus a whole new vine popping up like it finally felt safe to join the family. The humidifier now lives permanently with the plants. They claimed it, and honestly, they’re right. It works beautifully, and they didn’t lie — it’s very easy to clean.

## 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.
