There are a LOT of commercially available water filters out there, many can be gotten from the big box home improvement stores. What is a recommended replacement for the FW1 housing so I'm not stuck with buying the $30 (plus shipping) KW1 cartridges?
Any replacement filter assembly can be used that meets your needs.
Some folks want finer micron ratings, some want odor/taste eliminating.
Any big box store will have an assortment of whole home filters to choose from. Pick one that best suits your needs. You'll be able to purchase replacement elements for pennies compared to the KW1's.
