The Venta Humidifier Operates by the process of cold evaporation humidification, so you will not see any white residue, vapors, or mists. The disk stack rotates in the water creating a surface area over 45 square feet (LW45). When dry air meets the surface area of the disk stack, the water evaporates and is sent out into the room. By using the cold evaporation process, any excess humidity can be virtually ruled out.

The Venta Water Treatment Additive reliably prevents the growth of germs. You should clean the device every 10-14 days (empty the water, rinse the lower housing and the disk stack with water) because the washed-out air pollutants collect on the bottom of the water reservoir.

That depends on individual needs. Because the Venta Humidifier is very energy efficient, operating costs are very low even when used all the time. For consistent results, it should be run continuously.

Under ideal conditions, a humidity level of 40-60% can be expected. Some factors affecting humidity levels are heating/cooling, home insulation, the layout of the home, air circulation, furniture, floors, musical instruments, ambient indoor temperature, and the amount of water in the appliance. For severely dry areas or during the first days of use, you may notice the water evaporates more quickly and/or a lower humidity level will be reached. The water level of the lower housing should be checked and topped off daily.

 

The Venta Humidifier should be placed in the center of the room on the floor, or along a wall on the floor away from windows and any heat source. When using your Venta Humidifier for multiple rooms (larger model Venta Humidifiers) it should be placed centrally between rooms. Allow 18-20 inches above and on all sides of the Venta Humidifier to allow proper air circulation. Set up the appliance so it can draw in and expel air without any obstructions. That means free space above the appliance (e.g. not underneath a table) and a minimum distance from walls or furniture of 18-20 inches on all sides.

 

The appliance works best in closed spaces free of drafts to maintain a consistent level of humidity – just as windows and outside doors are closed when the air conditioner is running. Doors between rooms may be left open to allow for air circulation.

 

First and foremost, the Venta Humidifier is only humidifying when water is in the appliance. However, the Water Treatment Additive holds dirt and dust particles down on the bottom of the lower housing. When there is insufficient water in the lower housing, a red light indicator will appear and the motor of the LW15/LW25/LW45 Original Humidifier or the Water indicator will illuminate on the LW25/LW45 Comfort Plus Humidifier, and the unit will shut off automatically.

 

Simply give the appliance a general cleaning with the Venta Cleaner before using the Venta Humidifier again. Tip: Use of the Venta Humidifier Cleaner is recommended before storing the appliance for an extended period of time to remove any mineral deposits that can harden over time. You may also take advantage of Venta’s Ultrasonic Cleaning Services.

 

Every 10 to 14 days the lower housing should be rinsed/wiped out with a damp sponge. The disk stack should be rinsed off and/or brushed off with a soft brush or sponge. Periodically, the Venta Cleaner can be used for a thorough cleaning. At all times care should be taken to keep water away from the motor. For heavy build-up, we recommend cleaning the humidifier with a 50/50 mixture of water and white vinegar. Please see the user manual for more information.

Measure your space including any adjoining spaces that cannot be closed off (length X width) and choose the corresponding Venta Humidifier based on the coverage area. For factors such as vaulted ceilings, rooms with fireplaces, desert conditions, higher heating temperatures, musical instruments, exotic plants, or pets, we suggest going up one size to maintain ideal conditions.

 

The Comfort Plus Series utilizes the same natural humidification process as the Original Series, with the addition of advanced new features. The digital touch display with a built-in hygrometer shows the relative humidity in your space, reminder indicators for low water or necessary service, plus new settings for sleep and automatic modes.

 

The Original Connect Series utilizes the same natural evaporative humidification as the Comfort Plus models and even shares many of the same components. The key difference in the Original Connect line of humidifiers is the introduction of the Smart Life app. This allows for control via app from anywhere, or control by voice through Google and Alexa. We have also improved the sleep mode by making it possible to increase the fan speed while keeping the screen dimmed.

 

We recommend running the humidifier 24/7 at the highest speed for 7-10 days. In the first days of use, the evaporated water is absorbed by dry objects in the room (e.g. books, wooden furniture, textiles, plants, etc.). The optimal humidity is only achieved in the room after this stage.

 

Yes. Our recommended Venta Water Treatment Additive protects your humidifier from stubborn calcium and limescale deposits.

 

The Original and Comfort Plus Humidifiers can be set on a smart plug. When switched on again, the humidifier resumes with the settings last used.

 

This is the normal operation of the disk stack(s) in the Venta Humidifier in order to avoid vigorous splashing as well as keep the unit quiet.

 
  1. Possible mineral deposit contamination. Clean the black Gear Box prongs with white vinegar and a toothbrush
  2. Rubber coupling is not inserted all the way into the gear. Simply remove the Gear Box and reinsert securely.
  3. Call customer service for additional assistance at 888-333-8218

 

This is the normal operation of the Venta Humidifier, as it works through cold evaporative humidification.

 

It typically takes 2-3 weeks for the cleaning to be completed, though it may take significantly longer during the busy season due to the high demand. We recommend that customers have units cleaned during the off-peak season to avoid long waits for Ultrasonic Cleanings. For the current estimated wait time, you may contact Venta Support at 888-333-8218 or info-us@venta-air.com.

 

That depends on your individual needs. The Venta Humidifier achieves a greater humidifying effect the longer it is in operation. Over-humidification is not possible.

 

We recommend ventilating in short bursts several times a day. (Leaving windows open constantly drastically reduces the humidifying effect.)

 

Yes, it is suitable for continuous operation. It has an extremely low power consumption at a motor output of fewer than 8 watts (select models).

 

You can put the appliance back into operation without problems at any time. We recommend cleaning the humidifier before storage so that no calcium or limescale sediments can harden in the water tray.

 

After every 14 days, the Service indicator will illuminate to alert you that it is time to clean your humidifier. Once you have emptied your unit, rinsed the lower housing & disk stack, and added a new dosage of Water Treatment Additive, you can press and hold the Service indicator for 3-5 seconds until it disappears.
