The Boneco Ultrasonic U650 looks like a stylish, high-tech toaster that produces a plume of mist when it's in operation. Because mist has a natural cooling effect, you can set the unit either for cool mist (for hot days when cooling is welcome) or warm mist (for colder days when cool mist is the last thing you want in your house). Basic physics suggests that the warm mist (which exits the unit at 104 degrees Fahrenheit) is more likely than the cool mist to turn into water vapor, the invisible gas that humidity consists of, but both should raise humidity levels. A backlit LCD display on the unit's side (which can be dimmed for darkened rooms) displays the current humidity and lets you set the desired humidity level, mist temperatures and running times. A built-in hygrometer turns the unit off when the desired humidity is reached and switches it back on when the air starts to dry.
Because mist can produce surface dampening on surrounding objects, Boneco sells demineralization cartridges to remove molecules, most commonly found in harder water, that can leave stains on your furniture. Promotional copy claims that the unit is "whisper quiet" while in operation, so it won't keep you awake if you use it while sleeping or drown out your evening television watching. Amazon reviews for the device are all over the map, averaging out to 3-1/2 stars. Far and away the major complaint concerns leaking, which may either indicate poor quality control or a serious design flaw. Then again, some of the water spills produced by the unit may simply be the mist coalescing into pools of liquid water.
Humidification is important for health (because it removes germs from the air and loosens mucus in sinuses) and for keeping skin moist, but if you want to look elsewhere for a humidifier, this website covers a number of others. Look at the Air Innovations MH-505, the Taotronics TT-AH004 and the Levoit Hybrid Ultrasonic. For an extremely simple unit that's dishwasher safe so that you can be sure you aren't injecting germs into the air that you breathe, try the Miro CleanPot.
So far so good...No need for those expensive demilitarization cartridges, and no white dust!
The humidistat doesn't work. It was stuck at 35-40% even when the humidity in the room got to 80%...The machine does not shoot the mist high enough up in the air.
Immediately delivers a powerful mist into the air and can humidify a good-sized room up to 650 square feet rather quickly.
Its water container could be a bit larger since one will need to refill it 1 to 3 times each day.
I really like the hygrometer, which tells me the current level of humidity...you really need to clean it on a regular basis...it does require a commitment to maintenance.
Awesome variety of features, and completely silent while operating. More than worth the investment for quality.
