SP Bel-Art Cellulose Filter Paper Discs; for 10.25 in. I.D. Funnels (Pack of 100) (H14632-0010)

doesn't seem to work as well as whatman number 1, but they don't make a size for this funnel... so I ended up using a separate funnel with whatman number 1 as a secondary filter and low and behold i still catch particles.

They don’t work or seem to be the right size . Doesn’t actually filter properly
