I have considered vacuum filtration using celite and powdered carbon, but the materials cost would start to exceed the cost of the IPA. Standard activated charcoal would filter the IPA, but purity is a goal of mine. (Molecular sieves would be a much better option in regards to filtration, I believe.)
TBH, this is within my tolerance for risk and just one of several sub-hobbies that involve potentially dangerous processes. (Nothing illegal, of course.)
