    • Various embodiments of an end of faucet filter assembly (100) connectable with a faucet (104) on a standard sink (106) and having a plurality of outlets (118, 124, 130) corresponding with selectable modes of operation are disclosed herein. One mode of operation (116) provides unfiltered, aerated water dispensed from the filter assembly. A second mode of operation (122) provides a pulsing jet spray, while a third mode of operation (128) provides filtered water. One embodiment of the present invention also includes a connection assembly (162) between the end of faucet filter and the faucet that utilizes a water tight radial seal (218) that allows the end of faucet filter to swing or rotate back and forth relative to the faucet without impairing the integrity of the seal. Other embodiments of the present invention also include a filter cartridge assembly (132) configured to provide a user with an easy method of removing and installing the cartridge.

    • According to one broad aspect of one embodiment of the present invention, disclosed herein is a hand held oral irrigation device having a tip for dispensing fluids. In one example, an oral irrigation device includes a body portion, and a reservoir for storing fluids, wherein the body and/or the reservoir define a first major diameter at a lower end of the oral irrigation device, and define a second major diameter at an upper end of the oral irrigation device, the first major diameter being larger than the second major diameter. In this example, by providing such a geometry for the device, a user can grasp the device with one hand about the second major diameter during use. In another example, the body includes a pump for pumping fluids from the reservoir to the tip, wherein the pump includes an inlet valve and an outlet valve, the inlet valve including a reed valve made of flexible fabric material. The outlet valve may also include a reed valve made of flexible fabric material.
