Abstract

A faucet-mounted filter system that includes a body forming a fluid chamber having a water inlet, a quick connect device positioned adjacent the water inlet for mounting the filter system to a water faucet such that the water inlet is placed in fluid communication with the water faucet, a filtered water flow path disposed within the body and in fluid communication with the water inlet, an unfiltered water flow path disposed within the body and in fluid communication with the water inlet, a diverter valve disposed within the fluid chamber and operable to open and close the filtered and unfiltered water flow paths, a seal for sealing the fluid chamber, an actuator engaging the diverter valve to open and close the filtered and unfiltered water flow paths without having to interrupt the seal, a flow meter connected to the body and in fluid communication with the filter flow path, a filter housing connected to the body and having a reservoir, and a filter cartridge disposed within the reservoir. The filter cartridge is in fluid communication with the flow meter.
