How does the Venta-Airwasher/Humidifier humidify?

The disk stacks that rotate in the water have a surface area of over 5 square yards. When dry air meets this surface area, the water is evaporated and sent out into the room. As soon as the room has achieved an optimal humidity level, no more water will evaporate. In this way, any excess humidity can be virtually ruled out.

How does the Venta-Airwasher/Humidifier purify?

Airborne particles, such as dust, pollen and smoke will be drawn in and passed over the rotating disk stacks. The particles adhere to the wet disk stacks and get pulled down into the water. However, only pure water evaporates. The collected particles remain on the bottom of the unit and can be rinsed/wiped out every 10-14 days.

When is the best time to run the Venta-Airwasher/Humidifier?

That depends on individual needs. Because the Venta-Airwasher/Humidifier is very energy efficient, operating costs are very low even if used all the time.

What level of humidity can be expected and how often should the tank be filled?

Under ideal conditions, a humidity level of 40-55% can be expected. Some factors effecting humidity levels are: heating/cooling, home insulation, layout of home, air circulation and amount of water in the unit. For severely dry areas or during the first days of use, you may notice that the water evaporates more quickly and/or a lower humidity level can be achieved.

Where is the best place for the Venta-Airwasher/Humidifier?

The Venta Airwasher/Humidifier should be placed as centrally as possible (for multiple room use with some models). Allowances should be made so that air can be drawn in the top and blown out the sides. At least 18 inches should be left open on either side of the unit to allow for air circulation.

Do open outside doors and windows effect the efficiency of the Venta Airwasher/Humidifier?

The unit works best in closed rooms to maintain a consistent level of humidity- Just as windows and outside doors are closed when the air conditioning is running! Doors between rooms may be left open to allow for air circulation.

Can the water be filled above the axles where the disk stacks rest?

No problem. The tank can hold 3 gallons of water (model LW 42). The humidifying and purifying efficiency is only slightly lower during the first hours of use. Remember: the more surface area that is provided by the disk stacks, the higher the efficiency of humidification and purification.

Is it necessary to use the Venta Water Treatment Additive?

Yes. The Water Treatment Additive keeps the mineral deposits from becoming hard and difficult to remove – any sediment can be easily rinsed out. In addition, the Water Treatment Additive improves the efficiency of the unit by making the water sheet on the disk stacks, instead of "beading up" – allowing for maximum use of every square inch of the disk stacks. The Water Treatment Additive also prevents odors..

What happens if the water evaporates and the unit continues to run?

The Water Treatment Additive holds dirt and dust particles collected from the air down on the bottom of the lower housing. However, the Venta-Airwasher/Humidifier is only humidifying and purifying when water is in the unit.

Should more Water Treatment Additive be added when the unit has run dry?

No, because the ingredients of the Water Treatment Additive do not evaporate. Simply add fresh water to reactivate the Water Treatment Additive. One dose will help keep the unit from "furring" up with mineral deposits for 10-14 days.

What happens when the unit has not been run for an extended period of time?

Simply give the unit a general cleaning with the Venta Cleaner before using the Venta-Airwasher/Humidifier again. Tip: Use of the Venta Cleaner is recommended before storing the unit for an extended period of time to remove any mineral deposits that can harden over time.

What is the best way to clean the Venta-Airwasher/Humidifier?

Every 10-14 days, the lower housing should be wiped out with a damp sponge. The disk stacks should be rinsed off and/or brushed off with a 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. Please see User Guide for more information.
