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.

Great hardware, subpar software
4 Stars
Great hardware, subpar software
The good:I LOVE the ingenuity of this device! I prefer evaporative humidifier over warm and cold mist. Warm mist because the heating plate is A PAIN. It collects limescale like nobody's business. Cold mist because while spreading water in the air, it also spreads germs (my air purifier attests to that).But of course evaporative humidifiers have their cons too, mainly their wicks and their humidity efficiency (more on that later). This device FINALLY gets rid of those nasty mold sponges they call "wicks". This one you can just take apart and clean. It's also SUPER quiet, even on the highest setting which is a plus! It tucks away nicely and won't cause water damage to furniture (see picture) unlike the other types of humidifiers.The bad:Evaporative humidifier aren't as effective as the other types of humidifier. This one does a good enough job but I don't think it'll be able to maintain a very large living room. The humidity sensor is off by about 10% which makes it highly inaccurate as well.The ugly:The app. It's the most primitive app I probably have on my phone, and I have flappy bird on it. The only options you have are on/off, level 1-3 and auto where the latter does god knows what because I surely don't know and they don't bother explaining it! With the less than optimal humidity sensor the auto function is basically garbage anyway.There is no way of setting your preferred temperature unit, either. So on the home screen it says Celcius and on the actual humidifier it says Fahrenheit, gotta love that consistency.Lets talk about their ITTT system, or as they like to call it "automation". This is absolutely USELESS. you'd think you could bypass the humidifier's vague "auto" mode. But NO. The humidifier doesn't measure humidity when not running. So, if you we're thinking you could make it auto shut off and turn back on when needed, you're wrong. The only thing it does is auto shut off, but in my experience even that doesn't always work.I've just accepted that I have to manually turn it off and on to keep a somewhat consistent humidity in my nursery, and I'm not yet certain if that's worth the price tag.
