Review on High-Performance Shop Vac 903 98 Hangup Vacuum Cartridge for Efficient Car Cleaning by Rui Hanson

The filter that came with the vacuum has lasted for many years, although I regularly banged it against the garage wall to clean it. This one also seems to be well built. The first filter I ordered was too big even though it should fit most vacuums that are 5 gallons or larger, mine was 5 gallons. I recommend checking Shop Vac's website to make sure you get the right size the first time.
