I did a search but was unable to find a part number for a replacement filter to go in a Duo-Therm Quick Cool heat pump,
(model #630515.321).
The ones I removed were once white but now filthy, and made out of very thin, maybe washable material. But, they each have three separate pieces and are taped together, like in homemade.
What's everybody else here using?

Being this is a 2003 coach, those would usually be the filters for the
ducted Penguin units. Since you mention Quick Cool, is this a different unit?
I ran the model # and they are ducted Penguin units with these ceiling assemblies;

Since my last post I have found some of this filter material I had left over from a different job.

I cut a couple of pieces of it to fit up inside the AC return, on top of the two metal brackets. Then I laid
three Bounce dryer sheets on the grill assembly (also cut to fit) and installed the grill.
Now I've got two heavy-duty, washable AC filters with air-freshening qualities for about $2.50 each.
Thanks for your replies.
