The Stainless steel downpipe  rainwater collector connects to a single vertical rainwater downpipe and can filter rain  from a roof area up to 150 Square meter. The filter is installed  in the vertical rainwater downpiping to direct debris to the stormwater system and divert 95% of clean rainwater to the storage tank.  The filter also operates as a first flush device. This filter should only be used with round downpipes

The WISY downspout filter collector can be installed in vertical metal or plastic downspouts. The downspout filter provides overflow protection and diversion when the collection tank is full. Housing and filter insert are made of stainless steel. Filter mesh size is 0.44 mm (44 microns). Filter insert requires cleaning a few times a year and is dishwasher safe. This unit can be installed into a 80mm downpipe.
