I have owned a Harbor Freight (Chicago Electric, now Central Machinery) wet/dry vacuum for 12 years. It was a great price, but the original filter was getting thin and threatening to break. Now anyone who has used HF products knows that replacement parts are almost impossible to come by. They just don't have parts in stock. I think their marketing strategy is to just buy another product, whatever it is! So I looked for these replacement filters and found these 6 pack for a great price. They fit perfectly in the 5 gallon HF Vac and appear to be of good quality. The product description says it comes with a "cleaning tool", not sure if that could be it, maybe some kind of brush but there is no cleaning tool. Only 6 filters are included in the package. If they come anywhere close to the original (which has never impressed me with their high quality), this set of six filters will probably be the last filter I will ever buy!
