The filter replacements for Pentair DE line are expensive, close to half the price of the filter which comes with cartridges, around $130 per cartridge. There is a brand called Optimum sells a 4-pack on Amazon for a few hundred. Does anyone have experience with replacement cartridges by Optimum or companies other than Pentair brand?

So far, all the Optimum products I have used are good.
