The starters
At boxy 2-in-1 humidifier that looks big, but it’s smaller than you think. Venta LW25 Airwasher is not a pretty humidifier. You will not find any sexy curve, smooth panel surrounding the machine. At 13.7 x 14.9 x 7.6 in and 8.5 lb weight, it is about the size of a printer thus moving it around wouldn’t be an issue at all. Refilling the water can be a little bit tricky but there’s a water level sensor to guide you with it. Cleaning the humidifier can also be a bit hassle as internal parts including the disc stack would need to take out for an ultrasonic wash. Nevertheless, this 100% Germany made product has a solid build quality and durability for prolonged use. The entire components can be taken apart repetitively for maintenance without fail.

Before we begin, take note that there are 2 different versions of LW25: Classic and Comfort Plus. Let’s focus on the Classic. Venta LW25 Airwasher 2-in-1 Humidifier and Air Purifier utilize a very simple control setup. You have the ON/ OFF button on the most left, indicators on the center, and fan stage selector button to the most right. When you turn on the humidifier, the circle indicator will light on. If the circle indicator is flashing, there could be a faulty setup. The 3 numbering indicator will light up according to the current fan speed you’re in. Press on the fan stage selector button to cycle between them. Lastly, the triangle down indicator will light up once the water-level indicator is low and perform automatic shut-down.

What’s inside count
How fIlter-free Venta LW25 Airwasher 2-in-1 Humidifier Air Purifier works is simple. First, indoor air impurities are sucked into the wet surface of the rotating disk plate. The disk plate will trap all kinds of impurities in the water like dust, mold, pet dander, smoke, odor, bacteria, and germs. The dry air will now be moisturized and release out as an invisible mist through a natural cold evaporation process. If the air pulled in is already damp, only air purification will be processed in the treatment water.Keep it down
