When folding round filter paper the trick is not to fold it into perfect
quarters. The second fold should be for something more than 90 degrees say
about 95 degrees. This prevents the filter from sticking to the side of the
funnel. Thus there is more area free to filter liquid.

jun2605 from Lloyd Erlick,
It's a really good idea for selenium toner, too. I've pretty much stopped
discarding my selenium; I just keep topping it up when it runs low. Frequent
filtering helps keep it clear.
To make the solution pass through the filter relatively quickly, it's important
to have air *behind* ("under") the filter. I have one of those solid mesh
'permanent' coffee filters (not the gold-plated kind! There's always one
available at the Goodwill for pennies) and I put my paper filter (much finer
filtering than the mesh) inside it, and the whole thing goes into an ordinary
funnel. I found if I put the paper filter in the funnel directly, it went
through extremely slowly, because the paper sticks to the funnel. I tried one
of the filter-holding-funnels made for the purpose (a genuine Melitta with ribs
to hold up the filter ...) but it was only marginally faster.
regards,
--le
