I have two paper filter cartridges for my Sta Rite System 3 pool filter - one is 200 sq ft and the other is 100 sq ft. I have not replaced them since the pool was installed in the summer of 2008. They are starting to become a bit frayed - how long do they last? Is it time to replace them or can they keep going a bit longer?
These are fairly expensive - replacing both will likely cost around $350-$400 or more according to online prices and probably a lot more from a local pool shop here in Toronto.
