Coffee Filter during Pressure Cook?

Good day everybody. This may have been touched upon earlier but I cannot find any 'specific' answers. First time grain. Prepared soaked / rinsed seed in jars with polyfill lid and a layer of tyvek over the polyfill lid and then twisted the ring on. Over that I used a coffee filter with an elastic band; cut the excess of the coffee filter, applied a layer of aluminum foil and pressure cooked for 1 hour at 15 psi. I left the jars in the cooker overnight while it cooled. When I removed the jars to wipe them before inoculating I noticed the coffee filter was wet. I removed the coffee filters in a sterile glove box, inoculated the jars, put micropore tape of the innoc. hole and wiped the jars and lids with an alcohol swab. Afterwards I threw the wet coffee filters away and simply used the polyfill and tyvek as filters. They are incubating with a layer of foil on the top.
Should I be concerned about the wet coffee filters which I discarded? Why do we use those for pressure cooking. It makes little sense to me.
Thanks!!

we don't use them for pcing. some people put them on after pcing as a dust cover. you don't need a coffee filter dust cover if you have an aluminum foil one

Cool. I will keep that in mind next time. Just saw it in a tec. here and used it. So because I PC'd with coffee filters on is it going to have any negative effects on the substrate or anything? Keep in mind I swabbed the top of the jars after I inoculated and then put foil over that.

It's fine. Next time, just skip the coffee filters. They serve no purpose. Dust covers are not necessary. Simply remove the foil after sterilization, and leave the tyvek exposed to the air. RR
