If you're worried about humidifiers spreading germs, the Boneco S450 uses a centuries-old method of guaranteeing that the mist of water particles it produces is completely hygienic: It boils the water first. (This is why boiled water drinks like tea were popular long before the modern age of refrigeration. Boiling the water improved the odds that the liquid wouldn't harbor deadly diseases like cholera.) Boneco's Clear Mist technology won't scald you as it floats out of the unit, but it should be comfortably warm to the touch, which makes this humidifier a good – if expensive – choice for users in cold, dry climates. The boiling also keeps minerals in the water from escaping into the air and hardening on your furniture.
Don't be afraid that you'll burn yourself on the humidifier, either. According to Boneco, the unit has been carefully insulated so that, like the mist that it produces, it's only warm to the touch. The S450 can humidify an area of up to 850 square feet in size, so while it might not humidify your entire house or apartment, it can easily handle a large room. You can also put essential oils into the unit, turning it into an aromatherapy device, which seems to be a growing trend in humidifiers. The auto-cleaning mode will clean and decalcify the unit, so the only work you need to do it to keep it in good running order is to rinse the tank out afterward.
An illuminated control panel on one side lets you set on and off times along with the humidity level you want. If the light from the panel is too bright while you're sleeping, there's a dimmer mode that turns on automatically after you use it. The manufacturer estimates that running the unit continuously on the high setting will set you back $70 per month at most in electricity, so the impact on your bill should be minimal. (Setting the unit to turn off when you don't need the humidity should help further reduce your bill.)
The unit is well constructed...control panel is touch based, and is very sensitive and easy to use...very simple to setup and use, with the manual laid out clearly.
You might be surprised how many kilowatt hours this thing eats...So simple, but then so noisy. Sounds like a small pan of boiling water...device broke after three months.
So noisy...even on the highest setting, the humidity did not budge above 38% when I was aiming for 50%...it was very easy to set up and use, and it seems to be well built.
The steam is very effective...capacity is excellent, a large water tank that allows us to run it all night and the following day before refilling.
Very easy to clean. It lets you know when it needs to be cleaned...No messy moldy filters, or build up! I also like that you can set the humidity level.
It works for a larger home space in longer hours with each water refill. Also it is quiet when working...when you drop a few scented oil, it becomes an aroma spa diffuser.
