Review on Hoover 40110004 WindTunnel Final Filter by David Bone

I don't think anyone has the latest Hoover wind tunnel filter. These people sent me one for a self-propelled bagless vacuum, despite the name saying otherwise, and I ordered a non-self-propelled one. Another company sent what they said was the last filter but it is very flimsy and I doubt it will be of any use. I wonder if Hoover stopped making the last filter so people have to buy a new vacuum?
