Exactly what I needed although the product adverts and the packaging itself can be a bit misleading. I was looking for 4000, 5000 or 6000 filters for my wet/dry vacuum cleaner. That 4000 - 4200 really only means 2 filters out of 4000. The box actually tries to tell you two different values for it. Still, these are the Rigid 4000 filters you're looking for, and they're cheaper than buying two separate filters.
