I forgot where I saw it but someone posted a pic of a spec sheet on filters and according to the sheet PES filters aren’t compatible with BA/BB. Interesting story. I have filtered a few small batches and they start out filtering just fine. Around 20ml it starts to slow down by 50 it’s almost nonexistent. Thought it was me. Low and behold they are PES filters. Anyone ever use FOXX autofil PES bottle top filters and come across this problem. I’m going to get different ones because this has to be the problem. No way should a 250ml filter take a shit by 50ml. What filters are you guys using.
