That really surprises me. I don’t filter ales ever as I have noticed that it can strip flavors, especially at 1 micron. Plus they often drop clear within a week or 2 while carbing.
I will filter lagers to cut down on lagering time. At 1 micron they are crystal clear and the sediment in the keg is close to none. I mean very very close to none.
Are you pushing it through too fast?
