The Karcher WPD 200 Basic water filter is a configurable flow filter that is connected to the water supply network and supplies up to 100 users with hygienically impeccable drinking water of excellent taste. It produces three types of water: in the standard version - still (uncooled or cooled), as an option - saturated with carbon dioxide. The Active-Pure filter reliably retains chlorine and heavy metals, which also improves the taste of the water. The Hy-Protect filter retains bacteria and viruses, leaving minerals in the water. Filter replacement frequency: once a year.
