I know some of you guys filter. 5 micron is ok, or not fine enough? This is for clarity - getting rid of hop particulate, break material that got picked up, etc. I've seen a few systems that use a standard whole-house filter with a sediment cartridge. This certainly seems way cheaper than the SS plates that I've seen, and the polypropylene is AFAIK the same material as is used with plastic bucket fermenters, so backflushing with PBW/StarSan is doable. Has anybody tried this?
