Today I used a very strongly rolled up set of kitchen paper towels and stuffed that in the end of the funnel with a lot of force.

I pre-wetted the filter with ethanol and then added my mix to the funnel, it passed through relatively fast and the end result was clear of any zeolite.

So I guess just a simple solution like this works best and I will use that in the future.

For reference: I had 10g of the end product dissolved in 350ml ethanol 96%.

Currently I'm in the process of evaporating the ethanol, and I will now do one last quick filtering to remove any dust that was cought from the air.

Kind regards,
