Review on 2-Pack A-KARCK Cartridge Filter for Shop Vac # 90304, Compatible with Shop Vac 9030400, Fits 5 Gallon and Above Shop Vac Vacuums by Tracy Hector

Based on our own experience, we do not recommend this product. Though it claims to be compatible with our vacuum, it barely lasted a few weeks before breaking down. The only pro is that it was cheap, but the cons outweigh that - it does not work well, and we had to spend even more money to replace it. Save yourself the frustration and invest in a better quality replacement cartridge.
