Venta® Airwasher LW45 2-In-1 Humidifier And Air PurifierWhen we first started Venta Airwasher in Germany, nobody was interested in indoor air quality. There were only a few appliances on the market that purify and they used filters which have to be changed very often. The problem with filter is: They work perfectly on day one, but with constant use they clock and their performance drops. That`s why I instantly recognize the genius of the Venta Airwasher system: Humidification und purification without filters, just using the hydration and the cleaning power of water. Venta Airwasher corrects dry air by evaporating water. Look: The “Plattenstapel” – or the disks- act as collecting plates, picking up water from the units` reservoir. The dry air moves over the plates, picks up moisture and then exits back to your room, correcting any dryness leaving the air refreshed, invigorating and static free. And here is where an Airwasher is superior to a plane humidifier or purifier: While it quietly humidifies, the discs trap airborne bacteria, dust and allergens from the room down to an incredibly small microscopic size. Since colds and coughs bacteria, pollen and dust can’t evaporate, only humidified and purified air is free to exit back into your room. Maybe that’s why over 10,000 doctors worldwide have bought a Venta for their home or practice. In fact, Venta has won many awards from Europe’s toughest hygiene standard institutes. Here are the Airwasher advantages: They never over humidify. They trap airborne bacteria. They don’t produce ozone or white dust. They don’t use messy filters. In fact, every time you refill your Airwasher with water, it’s like you are installing a new filter. So an Airwasher’s performance never drops due to filter clocking. That is why we are Europe’s number one combined humidifier and purifier. A Venta Airwasher will guarantee you total indoor air quality, that no humidifier alone or purifier alone can give you.
