The Paris Rhone Ultrasonic Cool Mist Humidifier

I have a large and effective humidifier sitting on a shelf that straddles my living and dining room. While it works very hard, emitting a thick plume of mist, this device faces a persistent and vigorous opponent.

My oil furnace cycles on and off several times each hour during the dark months of winter. Every time it turns on, the furnace inhales the air within the house, warms it to a toasty temperature, and spews it back out. And when it does this, the furnace strips the air of every trace of moisture.

This competition results in rooms that are not particularly comfortable but still moist enough to avoid damage to my skin.

This presents a situation where a small humidifier, suitable for a single room, comes in handy. You place the device where you spend most of your time, using it to raise the humidity to a decent level. I practically live in the kitchen, which can become very dry because it is well heated by a pair of floor vents. To fix this problem, I placed a second humidifier within this room.

The Paris Rhone humidifier weighs in at three pounds. It is 12.6 inches tall, 9 inches wide, and 6.3 inches thick. This device is mainly composed of black plastic and comprised of two main units that stack together.

The bottom section contains the power assembly, atomizer, water reservoir, essential oil tray, air pathways, and control panel. The upper section is basically a 4-liter water tank with a tube that provides an exit for the mist produced below. Stradling the tank is the tank cover and nozzle.

AC powers this unit. Water from the reservoir is atomized and released back into the air. The operator can select how much moisture is released, set a timer, and turn on a night light using the control panel.

The Manufacturer

PARIS RHÔNE is trademarked by Euro-tech distribution. This company specializes in the design of innovative and convenient products.

Theory of Operation

Ultrasonic vibrations create a micro-fine cool mist that is quietly released throughout the environment. A fan is used to disperse this mist.

Depending on the setting, the Paris Rhone humidifier will atomize either 100, 200, or 300 milliliters of water per hour.

The Control Panel

The device’s display indicates the current humidity. Six buttons are employed to start the device, set the mist level, turn on a night light, and set a timer. You can also select Auto mode and, if lights bother you while sleeping, turn off the display.

Tests and Experiments

I temporarily turned the furnace off during my tests and set the humidifier to the highest mist level. Within half an hour, my kitchen’s humidity increased from 30 to 45 percent and was continuing to rise.

Once I restarted the furnace, it dried the air, dragging the humidity down to 28 percent. At this point, the ambient humidity became a rollercoaster ride. The furnace would dry the air and, when the house’s temperature rose, and the furnace turned off, the humidifier would add badly needed moisture.

The next day, the outside temperature rose to 32˚F. Before I knew it, the humidifier had pushed the ambient humidity up to 81 percent. I quickly turned the mist level down and switched to Auto mode.

Aside from the winter months, drastic changes in humidity will be rare, and the Paris Rhone humidifier should be easily capable of maintaining whatever level of humidity you desire.

The concept of using a humidifier to increase the moisture content of a single room appears to be sound. At this point, my large humidifier is maintaining the overall humidity within my house to an acceptable 41 percent. In the kitchen, my new Paris Rhone humidifier has managed to bring the humidity of this room to a more comfortable 48 percent.


When Auto Mode is selected, this device attempts to keep the room’s humidity between 60 – 65 percent. If you prefer a slightly drier atmosphere, set the mist level adjustment to Low or Medium, checking the humidity readout occasionally to ensure it reaches the preferred level.

Overall Assessment

This humidifier can be turned on, set to auto, and ignored until it runs out of water. Then, as you refill its tank, the device automatically restarts, using its prior settings. Despite this humidifier’s small size, it holds over a gallon of water, allowing it to operate between 14 – 30 hours.

If you are looking for an inexpensive humidifier that can effectively handle small to medium-sized rooms, the Paris Rhone Ultrasonic Humidifier would be a great choice.
