Review (5/5): Works, portable, quiet. Recommended. Works with colloidal silver water
[[VIDEOID:d19dbfbaa6bfd7091f083d97524d99cc]] I'm using this with colloidal silver water so it does get a dark spot at the top where it touches the vibrating pressure plate, I may eventually work out a tube/straw to feed a tiny portion of the filter as I'm not trying to filter out the silver, but I can still taste the metallic tang of the silver in the mist so I'm pretty sure it's getting through.
For when you need to change the filter, the top just pops off with a fair amount of pressure, it doesn't screw off. You'll basically need to grasp the "stem" part of the flower shadow with both hands and use your thumbs to apply pressure to the underside of the top part to dislodge it, there's a rubber gasket holding it together. Feels well made, not flimsy at all.
First button press=6 hours of continuous mist, 2 button presses=12 hours of 3 seconds of mist 3 seconds off etc etc for 12 hours as seen in video. The fairly loud fan noise is the refrigerator running. As you can hear in the video, the noise does not change when the humidifier is misting or not, it's almost completely silent. Phone camera is about 6 inches from humidifier.
Second button press after activating either mode (one press) =off.
It does need continuous power, it has no battery to recharge, I see that as a plus, one less thing to break.
