the better way to separate the zeolite  is through short path distillation of the cannabinoids, but since most people don't have a distillation apparatus and a heating mantle, micron specified filtration should be mentioned (not as safe as distillation in my opinion)

search for zeolite of specific micron (μm), 20-30μm will do, so if you filter the 20μm zeolite dust through a 5μm filter, the zeolite particles would be 4 times bigger than the holes of the filter, so the risk of residual zeolite in you distillate is low, the bigger the size difference between your zeolite and your filter, the harder it becomes for any zeolite particles to pass through.

keep it safe and do your own research.
