Some useful equipment

Has any one got a watering system for poly and/or garden that has a filter in it? I'm lucky enough to be able to take my water gravity from streams but there is always very fine soil particle sin the water so I always have to use the hose at full pressure to keep the tap clear and so can't run any sort of dribble watering. I need something with a removable filter that can be rinsed rather than a settling tank.
