WISY Rainwater Downspout Filter

WISY Downspout Filter Filters Rainwater from up to 1,600 sq. ft.

Available with 4" top.

The WISY rainwater downspout filter connects to a single vertical rainwater downspout and can filter precipitation from a roof area up to 1,600 square feet for irrigation, car washing, or other non-potable uses. The filter is installed above-grade in the vertical rainwater down-piping to direct debris to the stormwater system and divert 95% of clean rainwater to the storage tank or rain barrel. The filter also operates as a first-flush device. This downspout filter should only be used with round downspouts or with a converter kit providing at least 20” of vertical round pipe above the filter.

The WISY downspout rainwater 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. The housing and filter insert is made of stainless steel. Filter mesh size is 0.28 mm (280 microns). Filter insert requires cleaning a few times a year and is dishwasher safe.

Kit includes: mounting clip & screw, hose & tension ring
