I took out the factory filter, as it was a flimsy design just waiting for a problem, and installed a GE Smartwater Filter. The cartridges are around $15 each and they treat chlorine taste, hard water taste, sediment. You can even go all out and get one that treats VOC's like lead, cysts, sediment, chlorine, etc. for a little more money. I made the top of the cabinet a bit heftier and installed in about 20-30 minutes. I did not notice a reduction in flow at all from my water pump.
