Whatman Pre-Filters: where are they?

[Viator]

all the sites selling filters used to carry them, now I can't find them to save my life. They're the non-sterile ones for filtering out large particales that would clog a .45 or .20

I was just outbid on ebay on a box of 48 and the seller has no more, the buyer won't part w/ any.

Try coffee filters. That works OK.

Why not just double filter if you want to.. first use a .45 then a .22
