Review on Enhanced Cleaning Performance with Shop Vac 9034000 Cleanstream Filter: The Ultimate Solution for a Spotless Home by Will Rahman

An absolute must for every workshop vacuum. For most people, a standard filter in a store-bought vacuum seems to be sufficient. When I first started working with wood, I just let the dust fall and then swept it up. My nose got blocked with fine dust particles and the next day I started coughing. I quickly realized that I needed to wear a respirator while working to keep very fine dust particles out of my lungs. I don't think many people think about the effects of particulate matter. If you use the Shop Vac a lot, you need to understand that not all the dirt stays inside. The standard filter releases fine particles that pass through the filter. Worse still, these small particles are thrown back into the air for you to breathe. This is part of the two part system that we now always use in our shop vacuums. The first is a disposable filter bag for collecting garbage. This catches large particles and keeps them in the bag. When it's time to empty, we throw everything away. This keeps me from sucking in more dust when I throw away the vacuum canister. Just remember that if you use the "wet" part of the wet/dry vacuum you can't do this as you will ruin the bag. The other great benefit of the bag is that it prevents larger particles from clogging the HEPA filter and causing an untimely death. FYI, they make HEPA certified filters for most shop vacs. This (and the bags) allowed me to turn a very cheap Black Friday special into an industrial cleaning machine. Some might think it's cheaper to just use a standard filter and empty the canister; Have you checked the lung replacement price lately?
