I cut a strip of carbon filter and used double sided scotch tape to keep it in place around the circumference of the filter and up the tab (so it won't get lost).
I also had it hang out from the edge a bit to try and keep the filter off the coil, bit I doubt that is enough. But it should keep the filter off the bottom and that is where I was getting the most mold in my 2018 3 and 2021 Y.
Won't be until this time next summer if I know it is working.
