I just put my last new HEPA filter in an RK05 that I
am working on. There
are two styles of HEPA filters for the RK05. The original version is just a
box. The newer version has the inlet and outlet plenums as part of the HEPA
filter, and connects to the blower and a rubber elbow. The one that I just
installed was marked EQUIV 1212175. The DEC part number for the filter is
12-12175.
A quick Google search showed that there are 6 new ones on ebay for $35
each. Just search for the DEC part number 1212175.

I replaced my filters a little while ago, I was concerned about original
filters' deterioration, perhaps these will have decomposed over time even
if not in use. So I found a newly-produced filter, documented here:

But basically 3M Filtrete #0412560 carbon pre-filter cut to match the
original, from a tracing.
