Filters are reliant on surface area if they are doing true filtration. Otherwise they just grab particles above a certain size - there is no "cake". (the buildup on the filter surface is actually what does the filtration on a working filter).

I'd be looking for max surface area. I'd get a regular large-size water separator/filter and mount it to your inner fender. This way you have lots of area and so it will take a lot longer to clog. Just bypass the small prefilter for now, until you solve your issues, then later reintroduce. A big prefilter/water separator will do a good job protecting for a bit longer. Try to see if you can get a filter media a the same nominal particle size rating as the little plastic one.
