Q: Will there be mineral deposit buildup ?
submitted by DJohn49 - 23 days ago
A: We recommend using distilled water for best results. As another alternative, purified or filtered water will be slightly better than tap water. However, if using tap water, please be mindful that the unit may need to be cleaned more often due to mineral buildup.

This humidifier cannot be kept adequately clean. I cleaned it each time I was prompted to (programmed through the app) and still this is what it looked like between cleanings. I cannot risk circulating this mold and whatever else into my room.

I’ve always had a humidifier in the winter but still suffered from congestion and nosebleeds. I don’t know what is different about this one but it’s been the most comfortable furnace season we’ve had. It’s convenient to fill and I really like the app notifications. The nightlight is so cool, I’ll miss it in the off season.

Dissapointed - 3 months ago, Verified purchaser
It stopped working. It arrived last month and in use for 2 weeks or so. The machine doesn't recognize that there is water. We tried everything in the manual. When it was working, it provided good humidity for our open layout house, and it was very quiet. It is beautiful also. However, it shouldn't stop suddently after 2 weeks.
1 reply from Etekcity-Cosori-Levoit team - 2 months ago
We appreciate you sharing your experience. As a possible quick fix, try pressing the spring of the water outlet valve under the water tank to see if it is stuck. First, empty the water from the base chamber, then fill the water tank with two-thirds of the water and place it back to check if it works normally. Also, ensure that the water tank is properly aligned with the base. If the issue persists, please email our support team at support@levoit.com and mention this review. We are here to help!

Levoit never dissapoints. Water lasts way longer than I expected, even with the heater on. No white dust (At least while using Levoits Demineralization Cartridges). Aestically pleasing, compact. It has it all!

Question - 3 months ago, Verified purchaser
This thing sucks. It looks great, the app is easy but it does nothing. We’ve had this close to a month and when we start it, it starts around 25%. I’ve never seen it go over 35% humidity. I had it on all night last night and filled it this morning so it’s been on for about 20 hours straight and the humidity has only reached 22%, which I’m pretty sure is LOWER than it was when I turned it on. It’s in a small-medium size bedroom. Sadly I’m really disappointed in this because I was hoping the the sleek design, it would help the the dry air in the winter.

We are glad to assist you in optimizing the use of your humidifier. While the humidifier's effective range may be adequate for a room, kindly note that several factors can influence a room's relative humidity (RH). If water from the tank is draining, it indicates that moisture is being added to the air. However, in certain climates, the air may not retain the moisture effectively, which will be reflected in the RH percentage. Our support team would like to hear more about your experience so that we can better assist you. Please email our support team at support@levoit.com at your earliest convenience. We are here to help!

4.5 stars. LOVE the size, the heated or cool mist, variable heat for the warm mist, easy device interface, nice carry handle on the water tank, dual nosel let's you concentrate or diffuse the mist, the "lid" is large which make for easy cleaning inside the tank, can be remotely controlled in the app... (I have not yet used the essential oil tray) The negative- (why it's 4.5 instead of 5 stars) you MUST use the app to get the full adjustability of the settings. But USE THE APP. It's great to be able to adjust it remotely! If I forget to turn it off in the morning, I can log in to the app and turn it off. And I can save water during the day while I'm not home, but turn it on before I get home. (I haven't used the schedule feature yet.)
Fantastic

i really love this thing. i’ve had it about a week now and so far i have no complaints!! i was looking for a big humidifier for my room because i have such dry skin as soon as the seasons change even while living in the very humid state of florida. im so bad about remembering to refill my water tank and remembering to clean the humidifier and i love that this one lets you connect to an app that you can view and control the settings AND best of all it sends you notifications when you need to put more water in and when you need to clean it!!! i wish the nightlight was a little bit brighter but overall im very happy with this humidifier!!
Great humidifier for the money!

It gets so dry here in winter that we absolutely have to use a humidifier. It does wonders for us plus my kids. We have one in all 3 of their bedrooms. Public that it is so quick and easy to refill, even the kids can easily do it. It's a great portable size. And I love the mist function too.

Lady Feet Problems - 7 months ago, Verified purchaser
It gets a 3 b/c the main thing I need it to is humidify, and it does that. It doesn’t get a higher score b/c the hydrometer is CRAZY wrong and varies wildly minute to minute, and b/c it’s supposed to have multiple mist strength settings but no matter how I have it set, it just goes at full blast (tank only lasts about 20 hrs on lowest setting: same as on high). I should have paid a lot less for a more basic model with equivalent functionality
