Many window air conditioners use a 1/4" sheet of foam filter material
that I have used on PDP cabinets, and is available in rolls from
hardware stores and home centers. I also recall that some humidifier
units use a foam belt that is made from material similar to the original
DEC filter foam. Some the material DEC used is a bit thicker, but I
have been able to make the thinner foam work.

I also know that Sun Enterprise 10000 systems have a 1/4" thick sheet of
this type of foam on the inside of all the doors on the front and back
of the system. I am sure someone still makes it, but I don't know who.
