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.
