We like this product. It's made our home much more bearable in thick Juniper allergy season, and the humidity feels good on the skin. I think our indoor plants are happier too.

Advantages: Quiet, easy to service, cleans the air!

Disadvantages: Cost.

Since I am too lazy to fill numerous water tanks, for instance, one for each room, I wanted a large capacity humidifier. I became interested in this product for two reasons: low noise level and no replacing parts.

Before obtaining Venta's LW44, I was using LASKO's 1128 which was a satisfactory product except the two reasons I mentioned above. It kept the moisture level at what I was looking for. However, it was EXTREMELY loud, and I needed to run it in low level during the night otherwise it bothered our sleep.
Also, not only for LASKO product, but for all the rest of the humidifiers I had been using, exchanging filter every once in a while kept the running cost high and made me feel how dirty air we were breathing when I see the used filters.

I received LW44 about a month ago, and now I am extremely happy with my purchase.

At first, I was pleasantly happy with the noise level. Now I can stand the noicse even when I run in the highest speed. However, there was more important thing that made me unhappy. The water level did not go down, and I was very afraid that it was not working.

I called the distributor on Day 2, and they suggested me to continue using it for at least a week before bring back the product to their facility. (The distributor office is only 10 miles away from my office.)

Sure enough, in several days, the water started to go disappear in the air, and humidity level at home started to increase.

Now I refill the water every day, but it make sense as it is very dry here in the winter month in the area we live.

I read at Amazon that instead of Venta-Hygine Agent to use a dish detergent. It did not work as it still made the rotating disk dark and moldy. I switched to Tilex's Mold and Mildew Remover, and the surfactant work beautifully both to help disk to turn and to clean.

I have not reached to the point to clean the unit with Venta-Cleaner, but I am planning on using vinegar as is advised in the manufacturer's operation manual.

It is an expensive machine, but I hope this machine runs for several years even when I run 24/7 during the long winter months (6 months.)

Highly recommended.

Advantages: Very quiet. Low running cost (as I am not using the manufacture recommending solution liquid.)

Disadvantages: As some of the reviewers on other websites are describing, each parts is made of plastic and it is easy to break. During the first cleaning, the hinge part for the upper compartment broke although it was minor and do not affect the reassemble.

Venta LW44 is very quiet, my hygrometer says the humidity is 47%. The Airwasher is right beside me and I can not hear it at the #1 setting. Very nice machine and easy to maintain.

This machine is really nice. No noise, no misty mess, and is doing a fantastic job keeping a steady humidity level. The heating season here has just started at night. It is nice to wake up without stuffy dried out sinuses. Went thru the first cleaning the other day, a snap, all the gunky stuff was trapped in the bottom of the unit.

Advantages: Easy to use and set up. Only have to add water once a day or two. No noise at all. Easy to clean. No misty stuff spraying out all over the place! No static!

Disadvantages: A little expensive, but worth it if it will hold up thru the years.
