The Venta Airwasher offers the world a unique kind of technology by functioning without the use of filter pads. Dry indoor air is literally washed as it is drawn into the appliance and passed through the disk stacks rotating in water. Impurities in the air, stale tobacco smoke, household dust, pollen and allergens are trapped in the water, and only clean, humidified air evaporates. The Venta Airwasher works on the principle of natural evaporation which is widely recognized as the best method of humidification. No ions, no ozone, no white dust; will not over-humidify.
“Wherever I perform in the world: my agents are required to provide Venta Airwasher, because my priceless violin needs the best possible environment. Only Venta gives me the peace of mind that the air humidification will be perfect.”
Nigel Kennedy, Musician, London, United Kingdom
Venta is proud to share that their first US clients, the "Masters of the Impossible" Sigfried and Roy, are fans of the Venta Airwasher: "We love the Airwasher and we would recommend it to others who are interested in its benefits: no filter pads, very hygienic and super-easy maintenance. Venta Airwasher is already the top-selling brand in Germany and Europe and we wish them the same success in the United States."
Siegfried and Roy, Las Vegas, USA
"I can recommend the Venta Airwasher without hesitation. I have tried out a large number of air humidifiers and air purifiers. As far as I am concerned there is nothing better than the Venta Airwasher. It protects me from dry and bad indoor air. I noticed that particularly in Germany, when I appeared in the Classic Night in Aschaffenburg."
José Carreras, Tenor, Barcelona, Spain
"We have had the Airwasher in operation for over four weeks now, and I am happy to tell you that our experience and tests have proved highly positive. My staff and I are very satisfied with the appliance."
Prof. Dr. Dr. h. c. G. Pulverer, Director of the Institute of Medical Microbiology and Hygiene at the University of Cologne, Germany
"Since December 1987, we have had a Venta Airwasher operating in our executive office to our complete satisfaction. Its air purification has far exceeded our expectations. The Venta Airwasher is hygienic, easy to operate and maintain, and runs with a low noise level. We can wholeheartedly recommend this appliance."
Scheeler, Purchasing Dept., Deutsche Lufthansa AG, Hamburg, Germany
"The Venta Airwashers we ordered from you have been in operation in our 1290 sq. ft. open-concept office for several months now. Our staff is particularly bothered by the nuisance of dust within this building. The Venta Airwashers have greatly reduced that nuisance. These appliances make little noise and are really very easy to operate and maintain. The additives ensure that there is always a pleasant fragrance in the air. Maintenance is problem-free and the chore of changing filter pads is eliminated. We can recommend this appliance at any time and shall buy further units as the need arises."
L. Stegmann, Administration, Sanyo Semiconductors (Europe) GmbH, Germany
"On account of a marked allergy to pollen (hay fever) from which both my children and I suffer, I have looked for ways to help reduce the pollen count in our home and improve the indoor air at the same time. With the Venta Airwasher, it proved possible to significantly reduce the number of sneezing fits my children suffer during pollen season. The nasal mucous membranes dried out noticeably less as well. I have observed that the "dry nose" problem can be reduced considerably with the aid of the Venta Airwasher, even in the winter. By the way, you'll note that the plants in our sun room are also thriving."
Prof. G. Bastert M.D., Director of the University Gynaecological Clinic and Outpatients' Clinic, Homburg, Germany
"The Venta Airwasher has consistently been one of our best selling products during the winter seasons. We only have satisfied customers due to the dependability and long-term life of the product. The price is also reasonable: when you compare the cost of purchasing a separate humidifier, purifier and the filter pads that each unit requires, than you realize that within 2–3 years the Venta-Airwasher is actually the better value. Many of our customers buy the Venta Airwasher strictly on the basis of recommendation from their family and friends."
KaDeWe – the largest department store on the European continent, Berlin, Germany

We loved to sell the Airwasher: no complaints, no returns."
William Herring, Senior Buyer, Gracious Home, New York, USA
"Venta Airwasher is a home-run product. We are absolutely convinced of the incomparable quality and the unique technology. It's not cheap, but it's worth the money. No returns, only satisfied customers. I have recommended Venta to many fellow ACE dealers."
Jeremy Melnick, Gordon's ACE, Chicago, USA
