For spaces up to 2,700 square feet, Venta brings you the filter-free Kuube XL-T Airwasher, a dual-function evaporative humidifier and air purifier for large living and workspaces. We have developed Hygiene Discs to maintain cleanliness and soften the water inside the unit ensuring flawless performance with any water density. Designed for an energy-efficient operation, the Kuube XL-T features five speeds and works by drawing dry air into the unit, then releasing only humidified and purified air back into your space. Using Cold Evaporation technology, the Venta Kuube XL-T will not over humidify, nor will it produce ions, ozone or white dust as many other humidifiers in the market can produce. The Kuube XL-T features three ways to operate your unit: the digital touchscreen display, infrared remote or through the Venta App when WiFi is enabled. Easily adjust humidity levels between 30% to 70% in 5% increments, or enable the auto feature which allows the appliance to automatically regulate the fan speed based on the air quality in the room. Active for four hours a day, the built-in UVC lamp is designed for a hygienically flawless operation of the Airwasher by preventing the formation of germs and bacteria in the water. As with all our Venta products, the Kuube XL-T offers extremely low maintenance – just add water to operate. This model Airwasher will even alert you when it is time to enable its self-cleaning mode.
