Thanks. The site I first pulled up using this number indicated it was somewhere under 12” in diameter (around 10” ID).

Even the larger size you indicate might be a bit small for my Jet 1900, even though it would take two.

All that aside, I have a little Jet cartridge unit and, each time I cleaned the filter, a good portion of the dust would land on the plate between the mount area for the filter and the filter. Because of this, I’d start it up and it seemed my cleaning effort was a waste of time.

When I took the cartridge off to inspect for the whys and wherefores of the degrading performance, I noted the not insignificant buildup on the plate. It was obvious, to me, starting the collector again just pulled all the dust on the plate right back into the pleats again.

So, I took to shaking the entire beast, after a cleaning. When doing so, I noted a great deal of dust fall into the clear bag. After taking this approach, I noted a HUGE performance jump, from each cleaning.

From this, if I were to make an adapter to allow the smaller diameter filters to run on units intended for a 20” diameter bag or cartridge, I’d make the adapter several layers of plywood thick and the inside would be steeply beveled, sanded and sealed, to reduce the likelihood of the same kind of build up that happened to my plate happening with the adapter.

The P181038 is 17”OD and 23” high just like the Wynn 35 series filters.

You certainly could stack them with minimal modification and increase the filter area, but the single filter is already a significant increase in filter area over the bag that came with. I think without a larger impeller, more filter area is going to have minimal improvement.

On the PN P181038, since they re so small, do you stack three or four, or build an adapter to mount them to increase surface area for air draw?

Obviously, these wouldn t compete with the 20” diameter versions otherwise.
