Im probably gonna get raked over the coals for this but here goes: I ferment in plastic buckets with spigot. When I rack to secondary I rig up a funnel under the spigot. Inside the funnel I place a paint filter, such as one gets at an auto parts store for filtering auto paint. They work very well for catching hop and grain particles, and I have never had any infection issues, as alcohol has already been produced, taking care of any bacteria that might be present. Where I live, I can go to the auto parts store and get these filters free of charge, cutting down on my brewing costs as well. Im sure the sanitation police will start after me, but they have to find me first
