This is the right one for Vacuum Cleaner Bagless Whole House Reverse Flow Wind Tunnel-2 Model #uh71250. This is a rectangular filter [size 4 1/2" x 3 1/2" with a carbon filter slot (not included). Note that there are other rectangular filter parts for the Windtunnel-1 that will not fit. The quality seems a bit worse than the original. This works well for the right model.
