The filter size is correct, this replacement filter was listed for the shop vacuum that it was installed in. A week after installation, when I was about to unload the cleaner and clean the filter, I noticed that the gasket on the end of the filter closest to the engine was cracked. See photo. I have had replacement filters in this vacuum for YEARS and have never had a seal failure on the filters. He's only been in the vacuum for a week. Cheap item.
