    • Made my room so humid it set off the fire alarm. Great device
Style: Smart Humidifier Color: Gray
I have had this humidifier for 3 years and it is the BEST humidifier I have ever used! I only use it over the Fall, Winter, and Spring. Over the summer I clean it out and pack it away. It sits offline all summer and every time I go set it back up it just reconnects to the Wi-Fi and app and does not skip a beat. I have never had to reset/repair this device. It's smart features are extremally reliable. More reliable than most of my other smart home tech. As far as functionality goes this thing is nice and cool and super quiet. It also can crank out a ton of water! For example, you can set this device to turn off once the room humidity level reaches a certain point and adjust the speed. The other night I set it to max speed and disabled that limit so it would run all night. Something I do not usually do. Something else I do not usually do is close the bedroom door at night but that night it was closed. At 2am I was awoken by my bedroom fire alarm and my room was all hazy. It was so humid in the room it had looked like I was in a rain forest. The level of humidly in the room was almost 80% according to the humidifier. We live in MN and this month is super dry. If the fact this little guy put out so much water that it set off my fire alarm at 2am does not sell you, than I do not know what well. Would buy again. 10/10. ... show more

    • Just about perfect, but leaking after two weeks use
Style: Knob Control Humidifier Color: Gray
Update: discovered the leak issue was apparently my mistake. I had moved the humidifier a few inches by picking it up by the water reservoir indented handles. Apparently this was enough to break the pressure seal between the tank and the base. Took the unit apart, checked the float, which was operating fine, and refilled the humidifier. Marked the water level with a crayon and left it in the kitchen sink overnight. Leak had stopped and no water lost. This was operator error on my part. If you have moved your humidifier when water is in the reservoir using the indented handles, there is a risk of leaks developing around the water reservoir and the base. As precaution, I placed a dollar store cake storage pan under the humidifier just in case. Changing my review to five stars. Very happy with the quiet operation, ease of cleaning, affordable replacement filters, and it's ability to raise humidity in our 12' x 15' family room. Purchased four of this model as I trust the brand. Two were sent as gifts, and two are in our home. One began leaking two weeks from purchase. We are adults,no pets, humidifier is on the carpet and stays there. We don't walk through that area. Use soft water only and clean it every few days. Will contact Levoit. We absolutely love the compact shape, easy to clean, basic design. It is quiet and made a great difference in the humidity comfort level. It really does cover the square footage claimed. Other than it leaks, we really like it, but am hesitant to replace the leaking one with the same model. We also bought two Levoit bedroom humidifiers, round 2 liters, and they are fantastic. ... show more

    • Effective and unobtrusive

Absolutely silent. Clouds of vapor. Easy to fill and reasonably easy to clean. Phone app control works well and is easy to use.

    • Great Device with Minor Flaws That Can Be Fixed
Style: Smart Humidifier Color: Gray
I’ve had this device for a couple weeks and have a few issues I’d like to point out: The ‘low’ setting produces a relatively loud high-pitched sound that I’m very sensitive to, so I cannot sleep with it on low. Fortunately, I use the auto setting, which rarely drops to low before turning off. The noise seems to come from the ultrasonic diaphragm, not the fan or other components, indicating the device is likely operating as intended. I've seen similar behavior in other ultrasonic humidifiers after trying several models. Ironically, medium/high settings are quieter than low and just produce more mist without that dreadful high-pitch sound. The app should not be necessary for all features. Out of the box, the available settings are low, medium, high, and auto. Auto defaults to 50% relative humidity, which is unreasonable, as no online resource I could find recommends an indoor relative humidity that high. For use in winter the commonly recommended range is 30-40%, and anything higher could encourage mold growth or excessive condensation. The app is needed to adjust the target humidity, which I strongly recommend you do, otherwise, you risk wasting power, water, and creating adverse effects from excess humidity. The device really should have an additional button to adjust target humidity, or repurpose an existing like holding the power level button or something which could be added in firmware. Auto mode also needs improvement. It runs the humidifier full blast until it exceeds your target by 5% and stops, not restarting until humidity falls 5% below the target. When I set my target to reasonable 35%, the room stayed very dry at under 30%, and the humidifier barely ran leaving the room quite uncomfortable. I adjusted to 45%, so it starts at 40% and runs to 50%, which I’ve found is a nice balance where the room mostly hangs closer to 40%. However, auto mode mostly runs on high, producing an excessive amount of vapor. I had to push the humidifier to the edge of my dresser to avoid moisture on the wall. I can only imagine using this on a shorter nightstand next to your bed risks soaking your floor or bed with how much mist this thing can kick out. Additionally, firmware updates are applied when connected to the app, indicating potential fixes for some issues I’ve encountered could be made. The 10% range in auto mode is far too large. I believe a 5% range would be much more ideal. I’d like to be able to set to 40%, it would then run until 42.5% and start again after falling to 37.5%, maintaining a more comfortable and controlled humidity level. Limiting mist power in auto would also help. My previous Winix humidifier allowed you to set the humidity target and limit power level. I would prefer limiting mist to medium to avoid any issues with excessive moisture when on the high setting. I also found a bug. The device allows turning off the display while activating the nightlight, but in the app, if you turn off the display, it reactivates when you turn on the nightlight. This requires manual adjustments on the device itself before bed, which is inconvenient and can be fixed in the app. Despite these issues, I still consider this a very good product. It's visually appealing, unlike most humidifiers which look like an unsightly medical device, and it works well. It puts water in the air, runs quietly (except on low if you're sensitive to high pitch sounds), and its 'smart' features work relatively well. ... show more

    • Big improvement in humidifier design.
Style: Smart Humidifier Color: Gray
Very efficient humidifier. We have a very large bedroom. I didn't think I would like the phone app much but was surprised how convenient it is to have. I like the auto-shut off when the humidity gets 5% over target level. I filled the unit 4 days ago when it was pretty dry outside (I live in New Mexico, we do DRY very well). Some weather moved in and I still have 2/3 tank full since the humidity rose. My old humifier had to be filled twice a day regardless of weather. This model is much smarter and incredibly more efficient. I think it nebulizes the water to a finer mist so we get more humidity per liter. The night light is a nice touch (and you can turn it off with your phone, convenient when you're in bed and quite a distance from the unit) ... show more
