Too many variables. But one of the worst things you can do for a cartridge filter is to clean it too often, it shortens the life.
You should never use a high pressure nozzle to clean your cartridge. Buy the simplest, cheapest nozzle that you can find. You are looking for a pencil sized stream but not lots of pressure. Hold at 45 degree angle and wash the debris away. Never point straight into the filter if you can avoid it.
To avoid the need to clean so often, use a skimmer sock to catch the debris before is gets to the filter. There are many different types of skimmer socks available including pantyhose, paint bucket strainers, and hairnets.
Just curious, exactly how do they fail? Do they get clogged and you can't clean them anymore? Have you tried the TSP/Acid process?Mine don't last more than a couple of years. I suspect sun screen lathered on the grandkids is a big part of the problem.
They will usually tear somewhere in between the pleats or the rubber hosing on each end may crack. At least that's what I have seen.
