Rather than buying new filters, use your old expired KN95/N95 masks to at least mostly clean your IPA.
Print in PETG.
Caveats:
- Avoid using the masks unless the parts are heat welded together.
- External aluminium nose strips are generally glued, and IPA will dissolve that glue, reducing the quality of the IPA. Remove them completely in advance if possible.
- Carbon filter masks were not tested - this may improve or worsen your filtering. Or explode. Do a small test first.
- Old masks may have their elastics break quite easily. Some extra attachment may be required.
Considering the above caveats, I recommend first testing with your worst quality IPA.
