Filter Flosser is the best hand tool on the market today for cleaning all types of cartridge filters. It is 100% aluminum – not plastic. The comfort grip handle fits onto a standard garden hose and has an easy on-off / flow control valve for regulating water pressure according to the filter media type. The curved nozzle design creates a powerful converged spray pattern which generates a unique water & air agitation action that gets deep down between the pleats for a fast and thorough cleaning. All of our products come with a limited lifetime warranty and no competitor makes these claims or backs their products like us. Check it out!
