The Venta LW25 Airwasher is a humidifier for all seasons. Whether you’re heating your home in the winter or running the air conditioner in the summer, dry air can contribute to a multitude of health issues, including headaches, sore throats, dry skin, chapped lips, irritated eyes, chest and nose congestion, nose bleeds, allergies and asthma. Dry air also draws moisture from your nostrils, leaving you more vulnerable to colds, flus and viral infections.

Compact, efficient and powerful, the German-made Venta LW25 Airwasher is capable of humidifying rooms of up to 430 sq. ft. through Venta’s innovative cold evaporation technology, while naturally reducing allergens like dust and pollen in the air.

FACT: Every night we lose weight as water is lost through perspiration or water vapour in your breath – no wonder we wake up feeling dehydrated and unrefreshed

The Venta LW25 Airwasher only adds the precise amount of moisture required into the air, so there is no chance of over-humidifying the air like other humidifiers can. Overly moist indoor air can promote the growth of mould and fungi, a problem you never have to worry about with a Venta humidifier!

Unlike other humidifiers on the market, the Venta LW25 Airwasher produces no white powder, harmful mineral-laden aerosols, ozone, negative ions or other by-products that can affect those with respiratory ailments. In addition, most vaporizers and ultrasonic humidifiers can harbour bacteria in their reservoirs and release these into the room along with the mist or steam if they are not rigorously cleaned and maintained. The cold evaporation technology used in the Venta LW25 humidifier generates pure and bacteria-free moisture as particles simply cannot evaporate and are trapped within the airwasher.

The humidification and purification mechanism in the Venta LW25 Airwasher is simplicity itself. As dry air is drawn into the humidifier by an ultra-quiet fan, it passes over a disk stack that rotates in the water. Large particulates such as dust and pollen adhere to the wet disk stack and are deposited into the water in the lower housing where they become trapped. At the same time, pure water evaporates off the exchanger surfaces of the disk stack and into your home or office space, creating a healthier indoor environment.

The Venta LW25 Airwasher offers ultra-quiet operation and outstanding reliability. And being a green company, Venta designs its humidifiers to be kind to the environment, with all components being completely recyclable. The LW25 Airwasher is also energy efficient and economical to operate, consuming a mere 3-8 watts of electricity.

To maintain your Venta LW25 Airwasher, simply lift the top off of the humidifier and add fresh water once a day. Every 10 to 14 days, rinse the lower housing and disk stacks, then add fresh water and 1 dose of Venta Water Treatment Additive to improve the evaporation process and prevent calcium and lime build-up. The Venta LW25 Airwasher should also be cleaned thoroughly with Venta Cleaner twice a year. Cleaning is a breeze – just add the cleaning solution and water to the reservoir and run the humidifier on low for two hours.

FACT: A heated 100 sq. ft. room needs approximately 16 liters of water per day to achieve the medically recommended humidity level

The Venta LW25 Airwasher is ideally suited for humidifying bedrooms, offices or any room up to 430 sq. ft. For rooms with vaulted ceilings, fireplaces or wood stoves, hardwood flooring, wood furniture, tropical plants or pianos and other wooden musical instruments, Venta recommends going up one model to maintain ideal humidity levels. The same is true for homes in desert conditions or those with higher than normal heating temperatures. Available in White or Black (Charcoal Grey), the compact and stylish LW25 humidifier will effortlessly and safely create a healthier indoor environment for you and your family.

“I wanted to let you know that my two Venta LW25 Airwashers and Venta LW45 unit are performing beyond anything I expected. It hasn’t been all that cold until this week when we got down to -20C at night here. Although the humidity went lower, the Venta airwashers kept it at 35%, and today when I woke up we were at 50% because of the warm front. I am VERY happy with how they perform. And cleaning is so much easier than the damn cool mist humidifiers.”
Alan A., Toronto, ON
