Where to find micron filters & what is best type for filtering Hitech Buprenorphine pills?

[mixnmatch80]

I used to be able to find my info in here about micron filters but couldn’t come up with much in my search. Where can one find good quality micron filters these days that aren’t outrageously expensive, in my particular purpose for Hitech (small white pills with an 8 on one side and an arrow on the other) Buprenorphine 8 mg pills? I used to buy PES or PVDF whatman micron filters on amazon for $70 for a box of 100, now you cant get 50 for $200. So Whatman are out of my league now, so now I don’t know which brand nor what kind are best. What brands are high quality besides whatman? Are the PVDF or PES better suited for filtering bups? If anyone know of a place to purchase and what type are best, any suggestions would be appreciate. Just trying to be safe!

Aparantly the 'new type' are better for filtering pills. They also sell it in combination packs which include cookers
