Here’s my HF system with Donaldson filter. It works as well as the bigger Wynn filter.
I have since added a super dust deputy and now I don’t get anything at all in my collection bag I am assuming that means that I’m not clogging my filter either. I have bee; using it a lot since and haven’t noticed any suction loss.
