Syringe filter question

listen, the price is OK but are these units sterile? I don't see it inside of the sterile pouch.

Also.. 24$ shipping.. jeez

yeah .45 is whats preferred.. I just did a batch with .22 and it took forever.
 
sterile

far as i know they dont have 2 be sterile, the syringe filter is only for removing particles through the membrane, the ba does the rest

correct me if im wrong?
