The Venta LW25 Plus airwasher offers a simple but unique technology. The airwasher works without filter pads. Dry indoor air is drawn into the appliance and passes through the disk stacks rotating in water. Impurities in the air, stale tobacco smoke, household dust, pollen and allergens stick to the collection disks and are then trapped in the water. Simultaneously, clean water evaporates into the air, raising your relative humidity. The Venta Airwasher works on the principle of natural evaporation which is considered one of the best methods of humidification.

Every 14 days rinse lower housing and disk stacks with warm water. Wipe lower housing and fan blade with soft cloth. Recharge with the recommended dose of water treatment additive and fresh tap water.

Venta airwashers are constructed with sustainably in mind. Low power consumption and the drive for even greater energy efficiency are constantly optimized. Customers can expect a long lifetime and low maintenance when acquiring a Venta product. This is how Venta machines reduce costs in the long run. Made in Germany.
