Consider the Levoit Sprout [https://www.amazon.com/LEVOIT-Humidifiers-Evaporative-Adjustable-Nightlight/dp/B0DLGDRRXY/](https://www.amazon.com/LEVOIT-Humidifiers-Evaporative-Adjustable-Nightlight/dp/B0DLGDRRXY/) \- I now have two of them in a similar sized apartment as you - one in bedroom and one in living room / kitchen. I found that one was struggling to keep the entire apartment at a consistent 35-40% RH - which makes sense as they spec'd for 219sq ft rooms. While they can take tap water, I only use distilled water in them as my water is very hard i.e., very high in dissolved calcium and magnesium minerals, so I can go a bit longer without cleaning them and replacing the wick. One note: the external sensor that comes with the Sprout and must be used if you want to run in automatic mode will read about 10% higher than most hygrometers like the ThermoPro TP55 [https://www.amazon.com/ThermoPro-TP55-Indoor-Thermometer-Touchscreen/dp/B06XTPTG1J/](https://www.amazon.com/ThermoPro-TP55-Indoor-Thermometer-Touchscreen/dp/B06XTPTG1J/) Good Luck!

I use the VeSync app and access it through there to turn on or off and change its color.

I recommend an evaporative humidifier like the Levoit Sprout https://www.amazon.com/LEVOIT-Humidifiers-Evaporative-Adjustable-Nightlight/dp/B0DLGDRRXY/ - I now have two of them in a 770sq ft apartment - one in bedroom and one in living room / kitchen. I found that one was struggling to keep the entire apartment at a consistent 35-40% RH - which makes sense as they are spec'd for 219sq ft rooms. For a bedroom only - one would should be fine. While they can take tap water, I only use distilled water in them as my water is very hard i.e., very high in dissolved calcium and magnesium minerals, so I can go a bit longer without cleaning them and replacing the wick. Good luck!

Well not sure what your issue is with Levoit I have 2 Levoit Sprouts https://www.amazon.com/LEVOIT-Humidifiers-Evaporative-Adjustable-Nightlight/dp/B0DLGDRRXY/ - and have no issues and they satisfy your requirements except for being Levoit.

I didn’t want to use distilled water, which is an absolute must if you get an ultrasonic humidifier, so I got an evaporative humidifier - levoit sprout.

I am! It haven’t bothered setting up the app but even without it I’m happy with how it works. I love that I can use tap water.

After reading all the reviews etc., I got the Levoit Sprout (single room), and it has been great so far. Really love the top fill, ability to turn off all LEDs at night, the nightlight is actually kind of handy for evenings, and the sensor for auto mode. Top fill makes it easy to fill with a large measuring cup without taking off the tank that then drips everywhere. There’s an app, but I haven’t activated it for fear of future subscription fees. The auto mode with sensor (which I place on the other side of the room) works without Wi-Fi enabled. With my bedroom door closed, overnight it will bring my humidity up from low 30s to mid-40s %. I have also read good reviews of the next step up, their whole-house version which I think is called the 600 or 6000. Whatever you get, don’t get the cheap ones that just spit out visible vapor and coat everything with mineral dust. Those suck and do nothing. I think the one I have is a type called evaporative humidifier.

I would say to just avoid the ultrasonic ones, if you are looking for “low maintenance.” I bought a cheap model from the pharmacy when I was sick, and ended up returning it as soon as I read “must be cleaned thoroughly every day.” Nope.  Another Redditor suggested that I get an evaporative model for my bedroom. I ended up using the database pinned on the Humidifiers subreddit to sort by evaporative models, and was happy to see that there are so many models for smaller rooms too.  I got the Levoit Sprout, but there are a lot of good options out there. I wash it about once a week and it’s dishwasher safe!

Had a few LEVOIT OasisMist that worked pretty well. The warm mist feature is nice, but had to constantly get distilled water to avoid white mineral dust covering everything as it's ultrasonic. This year, just picked up LEVOIT Sprout as it's evaporative so can use tap water. Most evaporative models I've researched have mold problems, specifically in the unserviceable fan assembly as their designs have the fan after the wick, pulling moist air through. Sprout's design has the fan *before* the wick so it *pushes* the moist air out instead. So far so good.

Unless the fan assembly is user-serviceable, I would avoid evaporative humidifiers where the fan *pulls* moist air from the wick. Mold is typically an issue with evap units designed this way. The only one I've found that *pushes* air through the wick is the Levoit Sprout. This design avoid the mold issue developing in the fan assembly completely.

The Canopy has had mold issues in the past, specifically within their fan assembly that's not really user-serviceable. This is due to a design flaw that has the fan *pulling* moist air through the wick rather than *push*. The Sprout pushes air through the wick so the fan assembly will never have mold issues. Get the Sprout.
