As there are no filter pads, the Venta Water Treatment Additive can be added without causing any problem of clogging. Because the Venta system not only humidifies indoor air, but washes and purifies it as well. This is not possible with vaporizing or nebulizing appliances. There is also the danger of scalding in the event that the appliance tips over. In addition, these units can, depending on the model, use up to 20 times as much power as appliances that operate by evaporation.
Nebulizers require cartridges to avoid white dust.
Thesecartridges are expensive and changing them can be troublesome. Only by changing the cartridges regularly, can the user avoid the problem of releasing lime into the room with the water particles. The Venta cold evaporation system ensures hygienic long-term operation without filterpads. Dry indoor air is drawn in and passed through stacks of disks rotating in water. Dirt and dust particles adhere to the disk stacks and are collected in the lower housing.
