Downspout diverters direct rain water to a rain barrel or tank and preserve the existing overflow system.
Downspout filters are installed into downspouts, eliminating leaves, etc., sending clean water to the tank.
First flush filters remove the fine impurities (think pollen and dust) from the initial rush of water.
In-ground filters are high-performance cleaning devices typically used with underground cisterns.
In-tank filters can be installed inside or on top of water tanks, cisterns and rain barrels.
Industrial filters meet the performance needs found in large-scale rainwater collection systems.
