Rainwater filters are fitted to a downspout between the roof drain/gutter and the storage tank and storm drain system. Filtration diverts or removes most of the initial containments such as debris, dust, mold and pollen that have accumulated on the roof between rainfalls to be diverted away from the storage container.
