The original pre-filter on my 12 year old Hoover WindTunnel Supreme shrunk after several hand washes. The new one looks exactly like the one pictured in the ad and appears to be made from the same materials as the original. It fits snugly in the hole and I was able to easily put the cap on the filter. While the filter itself costs less than the cost if you're driving around looking for one, the added cost of convenience here likely outweighs the time and money you've spent tracking down the filter. I was also concerned that the old potentially harmful dirt that had passed through the bag could get into the fan and cause damage. We hope that a good replacement fit will eliminate this risk.
