Product Description
smartmi Cool No Mist Humidifiers for Bedroom, Home & Large Rooms
Are you annoyed by the white residues left over after long-term use of the humidifier?
Here comes your solution: cool no mist humidifier won't produce water vapor during evaporation. That means you don't have to worry about water stains or water impurities even after long-term use.
Designed with day-to-day use and security in mind, baby humidifier has been specially constructed with a separate water tank and electrical components. If the water tank is separated from the unit at any time, a sensor will automatically deactivate the baby humidifier for bedroom and shut off the cross-flow fan, so avoiding potential damages or injuries.
With a 4L water tank, evaporative humidifier for bedroom can work as long as 24 hours. Once the water reaches its minimum level, the unit will continue to operate for eight hours, evaporating excess water.
smartmi Cool no mist humidifier can be controlled with Mi Home App, allowing you to keep tabs on its sensors, temperature status, and water levels.

Smartmi Cleaning Advice
Cleaner recommendation
For the white sediment in the humidifier, you can add an appropriate amount of food-grade citric acid detergent for cleaning.
After long-term use, the odor caused by the growth of molds can be cleaned by adding an appropriate amount of hypochlorous acid solution.
Thorough Cleaning Steps
1, Add an appropriate amount of water (5L) to the pool, then add 1 bag of citric acid concentrate cleaner (24g/bag), then remove the evaporation blades from the evaporation tray one by one, and put them into the solution for 30 minutes of soaking. Then use a brush to brush down the stubborn dirt on the surface of the evaporation blades.
2, Reassemble the evaporation blade and put it back into the water tank.
3, Please add 100 ml of hypochlorous acid solution with a concentration of 100 mg/l, then dilute the solution by adding room temperature water to the full water level of the tank and soak it for 4 hours. Finally, you could rinse the evaporation tray and water tank with water.

The evaporative design of this humidifier means it emits no steam/vapor/mineral dust into the air and doesn't add heat to the room like some do. The design is also such that it helps to clean dust & airborne particulates from the air as it runs.
I live in a low humidity area and this unit keeps a 15'x15' room at around 45% humidity no problem. The unit uses about a gallon of water or so every 36 to 48 hrs to maintain that 45%. It works quite well, just sitting there quietly doing it job.
Maintenance is very simple. There are no filters or other throw-away items required for routine maintenance. I have found that using plain tap water, a basic wash/rinse of the "bowl" and disc assembly once a week to keep it clean (I use a very soft, long bristled brush to wash the disc assembly). It takes just a couple of minutes to clean and it's back up and running again.
I have had zero issues with mold/smells/etc.. I think good maintenance done frequently enough is the key to avoiding problems with smells/mold/etc..
Also worthy of note is product support, which is excellent.
I've had this humidifier for some time now and recently had an issue with the unit not starting up again after a refill and reached out to SmartMi support for help. I was promptly contacted by Rebecca from SmartMi customer support, who was very helpful and worked with me to get the issue squared away very quickly.
I'm quite happy with this humidifier as well as the support I received from SmartMi.
1/4/21- The humidifier has stopped working. It is full but now tells me that there is insufficient water in the tank and shuts off. I can’t get a hold of anyone via the help section in the app. We’ve had it less than a year and it’s already not working. I’m really bummed.
I am so pleased with this humidifier. We had been using cool mist humidifiers in my kids rooms and I was over the white dust getting all over everything constantly. I decided to give this one a try and I’m glad I did. The app is super easy to use and I love the childproofing feature that allows you to control the device only from the app (It keeps my 3 year old from messing with it). The app also provides a readout for room temperature, room humidity, and remaining water. It’s also incredibly easy to clean and has given me an hour a week back because I don’t have to try to scrub nastiness out of weird crevices like the cool mist humidifiers I’ve had before. And the best part? No more white mineral dust.
