That's unfortunately what I thought they were.
Sooooo I'm going to let you look up what a 1005 whattman filter is.
First of all that's a 2.5um filter and not a 0.22, that's literally an order of magnitude off so everything you've brewed is in no way sterile. Also, those are paper filters, not any membrane material used to filter brews.
Bottom line is you have not brewed anything sterile and you've put everyone who has ordered at a health risk.
I've got to get to the gym but I'll let
@Mighty-mouse @Logan44551 @T-Bagger @bolder and anyone else explain why a 2.5 micron paper filter doesn't work and you're whole brewing is fucked up
