Here's my solution. I intentionally ordered the cheap eBay filters because I wanted new not washed filters this time around. I knew up front they didn't have tabs but didn't care. Why? Because I have Gorilla Tape although any duct tape will suffice. I cut the strip into two halves and worked around the edge. Here's the filters in place better than any "tabs" could hold them with a much better seal IMO.
