I keep coming across conflicting details. A YouTube clip showed a person using a 4mm filter on a 3ml vial. But on this forum, the claim is that 1.5ml is the ceiling?
The maker's recommendations fall somewhere between 1.5-2ml. If you choose to force additional liquid through, is that possible? Absolutely, it can be done. However, as @boytres pointed out in his/her great earlier post within this thread, doing so carries certain dangers.
For my part, I simply stick with 13mm filters across the board, so I don't have to purchase several different sizes. A number of people prefer 4mm filters, while plenty of others simply can't be bothered with them.
Ultimately, whether you decide to use them and the volume of liquid you push through is completely your call. Nobody has ever faced arrest for ignoring manufacturer guidelines.
