Expensive Import, but Far Superior SteveInNYC ·

I've owned several humidifiers over the years, all them difficult to clean and maintain. The Venta Airwasher is by far the best humidifier I've ever owned, particularly because it eliminates the need for filters that invariably become moldy, or ultrasonic atomizers that are nearly impossible to clean. However, although much easier to clean and maintain, the Venta Airwasher does have a large tank of standing water that can become overgrown with mold, algae and bacteria. It's no wonder that Venta recommends a water treatment additive to keep such growth from occurring. Although there is no list of ingredients to allow a direct comparison to similar agents, the primary antibacterial agent consists of quaternary ammonium chloride, which is commonly used in competing products. However, the labeling on the Venta product also suggests that it includes a surfactant to improve sheeting action of the water so that it more uniformly coats the discs, and a demineralizing agent to reduce scaling and buildup on the discs. Because I had a leftover bottle of a competing product from my last humidifier, and because it cost a fraction of what the Venta water treatment additive cost, I thought I'd give it a try. Even if I needed to use more of it, it could still save money. However, there is a major difference between the two. products that proved to be crucial. The Venta product is non-evaporative. It is added once to the water after each cleaning and it reportedly remains in the water until the next cleaning. The competing product is intended to be added in small quantities each time the tank is filled. I thought that perhaps that was only necessary for a removable tank, but quickly found that failing to add more each day resulted in algae growth on the disc that faced outward, toward the window across the room. Adding the agent every day stopped the growth in its tracks, but at added cost. Further, I have to wonder just how much of the product is evaporating and then breathed in by my family. The other major difference between the two agents was evident in the form of a white sediment that formed when using the Venta water treatment. There was no white sediment with the competing product, but there was a white film deposited on exposed surfaces inside the humidifier. The Venta product not only prevents scale buildup, but it keeps minerals in the water from becoming aerosolized. The sediment that forms instead is easily washed away. I wasn't able to evaluate the claims of more uniform water sheeting on the discs, but am inclined to believe them, given the accuracy of the other claims. In summary, the Venta Water treatment additive may be an expensive German import, but it is vastly superior to cheaper products on the market and an essential part of Venta Airwasher maintenance.

The product is not packaged as shown on the website. It came in a bottle, not individual packages. I wanted the single package and did not get it. Please change the picture of the product and make it clear in the description.

My L44 is now 11 years old and going strong. There is not enough good to be said for this equipment. NO filters to get nasty and with regular cleaning it is a wonderful piece of equipment

Helps the Venta Air Washer work perfectly Pbird ·

A measured dose of this and the water is good to go for two weeks. I use plain tap water and have no problems with white dust or anything like that. The humidity is around 50% or a little higher. After years of using other humidifiers and struggling to keep them clean, I am so glad I discovered Venta.

Works well, fairly quiet. Maggie ·

This was recommended to keep our piano in good shape (we live in Arizona desert). The plus is that it's great for the rest of the house as well.

This is a must have item to keep a Venta humidifier working. I get 10 years out of their humidifier with use of this additive every other week. What other humidifier lasts that long?
