VENTAAirwasher Humidifier LW45 WHITE

Q: Is this a humidifier and air purifier

It says it's an air purifier, but according to consumer reports it does not purify the air, only humidifies it. https://www.consumerreports.org/cro/news/2008/02/claim-check-venta-airwasher-humidicleaner/index.htm

Q: How many hours does this machine (LW25) work for each fill of water?

Depends on what setting you have it on and how dry your room is. In my house with forced hot air which is really dry, I get about 24 hours per fill. I believe it is recommended that you fill it everyday with fresh water so expect that at least. I keep it on medium in our room which is 26x16. It does a good job of bringing the humidity up and cleaning the air.

Q: Are Venta Water Treatment and Venta Cleaner included in purchasing Ventar Airwasher?

I've had one for 15 years. Just pour a little hydrogen peroxide into the basin after rinse...clean with same..then add maybe 3 oz to the water Stays clean and easy cleanup!

Q: Can the Disks be Cleaned in an Ultrasonic Cleaner, and if Yes can Someone Suggest a Specific Ultrasonic Model?

We clean the disks in our Venta with the cleaning solution recommended by Venta. We have the LW45 model that keeps 2000 Sq. feet at 30 to 35% humidity. We have a geothermal heating unit and live in a moderate climate, although so far this winter we've been unusually cold but the Venta has kept up.
