This humidifier has a water pump that transfers water to an upper tier section where the ultrasonic transducer is located, it creates water vapor through ultrasonic vibrations, and a fan in the bottom of the unit blows air upward causing the humidity to blow upward from the top of the unit.
This humidifier is definitely simpler to fill with water compared to some other humidifiers, all you have to do is fill a container with purified or distilled water and pour it into the top of the Honeywell.
I customized my Honeywell humidifier with a rectangular piece of plastic that I cut to fit the top shape of the humidifier, it protects dust buildup that would otherwise fall into the water reservoir.
This Honeywell humidifier does spatter a bit of water onto the top of the unit when it is humidifying, this is only because the ultrasonic transducer is located near the top. This water spattering is slightly annoying, but if the humidity dial is turned down, the water spattering reduces to almost nothing on the lowest setting.
This water spattering effect does not happen with ultrasonic humidifiers that have the ultrasonic transducer located near the bottom, but those units do not have a water pump, which has an overall positive effect of constantly mixing the water in the reservoir, and also causes less gunk to build up directly on the top of the transducer, since the water is flowing when the humidifier is on.
This humidifier does not have a humidistat, so it needs to be turned off once the humidity has risen to the desired level, but in my experience with humidifiers having humidistats, is that since the humidity is emitted from the device, built in humidistats usually are way inaccurate because the humidity directly surrounding the humidifier rises more than in the rest of the room.
In my included pictures, you can see a green/blue colored X-Power fan pointing upwards, this has an invaluable effect of blowing the humidity upward and dispersing it far into the room.
I also have my humidifier plugged into a remote controllable appliance module, it has a small remote with an off and on button, and the appliance module is a small rectangular device which plugs into the wall outlet and the humidifier plugs into it. With this seutp, all I need to do once the humidity rises, is press the off button and the humidifier turns off, of which I have an indoor thermometer which also has a hygrometer, and it displays the room’s humidity level in percentage, I find that around 50 – 55 % humidity is optimal.
Room digital thermometers which have a hygromter, and remote controllable appliance modules can be purchased at most home improvement stores.
Quite a few other humidifiers available, cost quite a bit more and are also more high maintenance, it is mostly the water filling process that is a hassle with humidifiers having water tanks needing to be removed from the unit, before the tank can be filled.
Do not expect the best results if ever trying to use plain tap water, as this will cause the impurities in the water to be expelled in the mist, and it will produce a white layer of dust throughout the room, this is common to all ultrasonic humidifiers. PURE WATER = NO WHITE MIST
This humidifier does not have any hard water deposit filters, so always use purified or distilled water, and this will avoid hard water deposits that will occur if using plain tap water.
Overall this is a nice humidifier.
