All WISY filter inserts are designed for very low maintenance. It is virtually impossible for debris or dirt to stick to their smooth, stainless-steel surface. As a result, the filter inserts have a long service life.
The filter insert is easily accessible and protected against backflow in the sewer system. When necessary, the insert can be removed from the housing in just a few simple steps for cleaning by a high-pressure cleaner or in the dishwasher.
