What size filters?

What size filter do you use with an oil? with peg? water?

.45 oil and .22 with water based

Why .45 with oil......
i use a .22

not necessary, and takes to too damn long. If you want I can dig up the thread from a while back, but basically the contaminants in water will pass thru a .45, but those contaminants (mainly trace metals and dissolved solids) are not found in oils. .45 is large enough to trap common bacteria and molds that we try to avoid
