I followed someones woes after investing in something very similar from a well known US supplier of shiny brew kit, it involved a kettle drain upgrade to a wider bore and tri clamp flange valve, and it clogged rapidly until a SS pan scrubby was sat in the drain mouth prior to the tube filter, and i suspect would do just as good a job on its own..

So i would take a punt on a SS pan scrubby from the pound shop first

edit.. iirc the tube filter from the US was targeted at filtering 'dry hops' from a conical fermentor which could take pressure to drive the beer out through the filter..
