Along with our large selection of chimney brushes, we also carry a variety of dryer vent brushes to prevent lint fires from dryer vents. Lint buildup can cause deadly home fires but can be prevented by cleaning your dryer vent with our inexpensive brush kits. Round Pellet Stove/Dryer Vent Brushes can be used on dryer vents or pellet stoves. To ensure that you get the correct size brush be sure to measure the diameter of the inside of the flue and get a brush that is equal to that size. If your vent measures 4" get a 4" brush, if your flue measures 5" get a 5" brush.
