What does a
rainwater filter do?
A filter for rainwater removes coarse and fine impurities such as leaves, sand or pollen from the rainwater before it enters a cistern or rain barrel. This improves the water quality and protects downstream components such as pumps, pipes and consumers from damage and deposits.

High cleaning performance: All WISY rainwater filters - whether downpipe, cistern or vortex fine filters - rely on the vertical filter mesh.
Robust and efficient
Rainwater filter
The rainwater is efficiently cleaned by a fine stainless steel mesh. The available mesh size of the filter fabric starts at 0.1 mm (100 µm) for industrial requirements. We use 0.28 mm mesh size as standard for our rainwater filters.
This reliably separates leaves, moss and smaller particles that are carried along, permanently flushes them down the filter fabric and then transports them into the sewer or an infiltration trough.
Low maintenance
despite fine mesh size
Thanks to the vertical arrangement of the filter mesh, no dirt can remain on the fine stainless steel meshes and block them. This results in long maintenance intervals for the filter and cistern. The water in the cistern remains clean in the long term.
Long intervals
and easy to clean
All WISY rainwater filters are particularly low-maintenance. An inspection twice a year is sufficient. The filter insert can simply be removed from the housing and cleaned in the dishwasher. Cistern cleaning is only necessary after 15 years at the earliest.
As the filter insert is made entirely of high-quality stainless steel, it is extremely durable and only needs to be replaced after 20-25 years at the earliest, if at all. The housing of each filter is also made of particularly durable material.
Safety
in the rainwater filter
The open cross-section of the connected pipes is maintained throughout the entire rainwater filter. This means that even larger solids can pass through unhindered. Even a tennis ball flushed from the roof cannot cause a blockage in the rainwater downpipe, as the rainwater filter does not constrict.
