The new Venta Airwasher LW45 large room humidifier in dark gray gives you a large tank capacity, cold evaporation high humidification and helps clean the air. Stop worrying about filling up the tank with water, the Venta LW45 large capacity humidifier gives you up to 3 gallons of water storage. An automatic shut off stops the machine once it is out of water, saving wear on the machine and wasteful energy consumption.

How It Works

The Venta Airwasher LW45 large room humidifier draws dry air into rotating disc inside the machine. Water is brought up to the air through the rotating discs and humidifies the dry air on contact. Humidified air comes out the sides of the Venta LW45 at an automatically set 45%-55% humidity. Dust and other particles drawn in with the dry air become too heavy and drop to the bottom of the water tank. This process gives you a consistent and safe level of humidification.


Ventas do not require the changing of any pads, filters, mineral cartridges or wicks. Simply treat the machine every 10-14 days with the Venta Water Additive and run the machine with the Venta Cleaner every 3 months. The particles that are trapped by the machine that are left over after the cleaning should easily wipe away. Since dust and other particles are trapped at the bottom of the tank the Venta LW45 does not release any white dust keeping your room nice and clean.

New Features For the LW45

- The redesigned Venta Airwasher LW45 features a newly designed water tank that helps funnel the sedative and particles towards the bottom of the water tank, making the machine easier to clean.

- Additional coverage. The Venta LW45 large tank humidifier can humidify up to 800 sq ft. That is an additional 60 sq ft. over the older LW44.
