BOYON Ultrasonic Cool Mist Humidifier 5.5L, Top Fill Humidifiers with Humidistat, Cool Mist Vaporizer with 3 Mist Settings, Waterless Auto-off, LED Display with Nightlight, Last up to 40H

Little machine is easy to use and refill. Used 2-3 months so far. Have hard water so scale builds up in the bottom and central mist chamber, but no noticable chalky dust emitted outside of the machine. Weekly cleaning with bottle brush (had to buy specific one for this) removes most buildup and small amount of pink mold that accumulates. I'm not sure what the flat filter with beads actually does.. It is difficult to put back together and would be annoying if beads spilled out while rinsing. Have kept this running 24/7 on highest humidity and output setting with lid open. Needs to be refilled about once a day. Placed in 400sf living room with vaulted ceiling (& forced air) so circulates throughout house. Could use a larger unit but chose this simple design over an evaporative type with wick that would need chemical additives to keep clean. Have noticed a bit less static in the house and less dryness when breathing. Fairly pleased.

I received this humidifier today, to replace a TaoTronic humidifier that's not top loading and that can't be used with tap water. At least with the TaoTronic unit the automatic humidistat worked perfectly. It was within 1 or 2 % of my room hygrometer. This humidifier is off by 8 to 10%. And it apparently is quite sensitive to water, which is ironic since that's what this thing is designed to work with. Two particular "sensitive" areas are the air intake column and the front screen. According to the manufacturer if water gets in the air intake column or if water gets into the screen the unit won't work and you have to wait 3 days to let it dry out before you can get it working again. (Kind of like a drunken Hollywood has been.) That's pretty ridiculous for a machine that runs 100% of the time on water, and which needs weekly cleaning and refilling multiple times a week -- with water.I was so frustrated in the first day or two that I decided to send it back and get another brand. In the time it took to get the other brand I was at least able to determine, via a separate room hygrometer, that while the humidistat is, in fact, 8 to 10% inaccurate (high) by compensating and simply setting the unit 10% higher than I want (55%), the room balances out nicely between 45 and 50%. It never goes below 45%, and never goes above 50%. I can live with that, especially since it's been running now for over 72 hours and I still have 1/3 of the tank left. That allows me to go away for a long weekend and not have to worry about the tank running out of water. (Note: I'm using it in a small bedroom that I don't use, with the door always closed, to store my guitars.)The unit is quiet. The remote is nice. And I'm using tap water/hard water that's only filtered to remove some chemicals but not calcium. I've seen zero white powder despite the fact that the unit has been running 24/7 the whole time. It's top filling and that's convenient, plus it's easy to clean, since you can lift the top and have full access to the tank. The main thing, apparently, when cleaning it, it to avoid dumping out the base water out on the side where the air intake column is. (There's a note right there telling you not to dump the water out on the air intake column side.)So all in all...I'm going to give this an extended try and hope for the best.

After having several vaporizers and humidifiers throughout the years, I splurged on this purchase for a cool mist humidifier to place in our bedroom during the colder months due to the dehumidifying effect of running the heat unit in the house.This humidifier is quiet and delivers a cool mist at three different levels (Low, Medium, High). It operates from a small remote control pad with buttons or from the front panel.Pressing the Lighting button once cycles the LED lighting through several colors. Pressing the Lighting button a second time freezes the lighting at the color being cycled at that time. Pressing the Lighting button again turns the light off, allowing you to begin cycling through the lighting options again.The “Fog” button allows you to cycle through intensity of cool mist effusing from the Unit, between low, medium, and high.Pressing the “Sleep Mode” button turns off all lighting from the unit (including the front panel) while continuing to emit the mist while you sleep.I have not yet had the chance to clean the unit so will not comment on ease or difficulty of cleaning.I also have yet to use the timer mode on this unit.Again, this unit is very quiet and will not disturb nighttime sleep or a daytime nap. I am extremely satisfied with this purchase and product. I highly recommend to anyone looking for a really good humidifier that surpasses your standard big box store or pharmacy brands.

Quiet and beautiful. I would have given it 5 stars but I didn't like the location of the essential oils tray. I'd seen several humidifiers with the tray near bottom edge so when this one said it's at the bottom I assumed it was on the side but NEAR bottom edge. But no... it's literally on the under side of device. So you can't add essential oils unless the humidifier is empty. Very disappointed in this feature. I almost sent it back but I have a diffuser in the room already so it's not a huge issue. Just won't ever use the one on the humidifier.

I purchased this for my mother's assisted living apartment. When it's running, it can make her two bedroom, two bath unit comfortably humid. Unfortunately, it came without any operating instructions. It shuts itself off at random and then takes a lot of futzing around to get it started again. I assume it's a problem with the timer, but we have no clue how to set that.Love the little remote that comes with it. And, as I said, it's amazingly quiet. The facility maintenance man says it's the nicest one he's seen. It is very easy to fill, even for a 92 yr. old.
