The Boneco Ultrasonic U7147, with its LCD display and push-button controls, is about as high-tech as automated humidifiers get. Using the control panel on the front of the unit you can fine tune your relative humidity between 30 and 80 percent, and set the humidifier to run for a set period of time or continuously until its three gallon water tank is empty. As its name implies, the Boneco uses ultrasound to fractionate water into a fine mist and, because the water is heated on its way out of the tank, the microscopic droplets rise up through the chimney-like internal shaft of the unit to release the mist into the air.
The Hydro Cell filter, which you'll need to change every one to two months, keeps the mist clean and fresh, so that germs won't be released along with the humidity. (You can simply refill the filtering materials in the Hydro Cell from the supplied packs instead of replacing the entire cartridge.) The ultrasound unit in the Boneco is advertised as being "whisper quiet," a point on which Amazon reviewers tend to agree. This should be a relief for those who don't like the rattly fans in units like the Honeywell Quiet Care HCM-6009, but a disappointment for those who find that the white noise produced by some humidifiers helps them sleep.
The mist nozzle on top of the unit rotates, so you can aim it wherever you need the humidity the most. (Indoor gardeners might want to turn it toward the nearest potted plant.) A warning icon on the LCD display lets you know when the water tank needs to be refilled. A cleaning icon will light up when it's time to clean the unit. You can buy Boneco's EZCal Cleaner and Descaler powder to remove mineral build up in the unit's interior. (Mix it with water before pouring it into the unit and shaking it.)
For some alternate approaches to home humidification, look at some of Boneco's competition, like the Taotronics TT-AH004, the Guardian Technologies PureGuardian H8000B, the Dyson AM10 and the relatively low-tech-looking Taotronics TT-AH003.
Easy maintenance. Shuts itself off when water level is low, runs smoothly, runs silently...A great investment, and we're so glad to have this!
Too much maintenance. It blinks every 2 weeks until I stop it to remind me to clean it...requires 2 filters which is costly and with decent water quality unnecessary.
It's been completely reliable at adding humidity to the air. It involves some easy cleaning every two weeks...generates a white powder that deposits on our television screen.
Not easy to fill...It uses a lot of water even on the low setting. One tank will only last one night. The filters are also expensive...high maintenance.
I am very satisfied with the quality of the product and its work. Moisturizes quickly enough and works quietly enough, D does not interfere with sleep.
Quiet, well humidifies the air, there is water heating...you need to put on a stand. If you put on the floor - the floor becomes wet.
