I use a stainless 100mm wide funnel with a standard coffee cone filter in a bottle. I then place the big funnel on top. Then a large basket coffee filter is added. Then i add the IPA to be filtered.
Normally even with a large blob of the jelly like residue in the IPA does not block the large filter. The liquid slowly drops out of the jelly over time saving lots of coffee cone filters.
I have only tried this a few times. So far i have only used one filter of each type every time.
