So I'm trying to decide which filter would be best for me. I've read that using a 22 is the only way to be 100 percent certain that no bacteria enters your final product. I've also read that 22s are intended for filtering water based solutions, and therefore are pretty slow and tedious when used with oil. If one were to be filtering say 100ml of oil through a 22-how much longer would it take with the 22 than it would with a 45? Sterility's obviously my #1 priority. If I decide on the 45 would I have to then bake the gear after filtering to be certain it was clean?
