Filter Material

The filter material is cut about .5" bigger in diameter than the bucket at the level it will be pushed down to. This makes it about 11" in diameter. The more flexible the filter material the less critical the size it can be made bigger and will still stay flat once put in. Start with a stiff "universal washable filter" or optionally the barbecue replacement Grill this holds the filters flat and a bit away from the fan.
