When fine filtration is not needed, this filter can be used in place of the standard filter bag to capture large amounts of debris. Simply empty it into a trash bin when the vacuum is full. Ideal for use when vacuuming material with a coarser consistency. Fits Fein Turbo I and Turbo II vacuums (#52876 and #58694 sold separately). The Fein permanent fleece filter Reduces the expense of replacement bags when total dust containment is not necessary.
