Most folks involved in the Portland Protest now know that it is nearly impossible to find a reliable source of P100 filter cartridge replacements. These cartridges only last a few hours of continuous use and must be replaced.
I have been rebuilding mine at a cost of about 3 dollars per cartridge. They are as effective or better than the original.
Materials List:
Super glue
3m microallergen/HEPA vacuum bag
HEPA AC filter
Activated Carbon (pet store in the aquarium section)
small pair of wire cutters (Diagonal pliers)

This is for the cartridge style. The packout style process is basically the same. except all of the cloth filter goes in the packout (pink/white plastic cover) portion and the inside carbon needs to be replaced less often.
this is the outer facing portion of the filter.
use the Diag pliars to cut the spokes off as close to the rim as possible.
when you have removed the top pull the peice of cloth out to expose the spent carbon pellets and dispose of them you will have something that looks like this
Use the old cloth to as a template to trace replacements from the Vac bag and the AC filter
you will need to carefully remove the cardboard from the ac filter and flatten it.
you should now have two circles of vacuum bag and one circle of ac filter
place one of the vacuum back papers on the bottom of the cartridge then Refill your cartridge with clean Activated carbon.
Place your second peice of vacuum bag on top of the carbon and place the AC filter on top of that make sure to glue the edges of the paper to keep your carbon in. then using your superglue reattach the top screen
Everything I used is available at your local hardware store/pet store. It is the exact same material that 3m uses to make these. Total cost was $40 including tools. this will refresh your cartridge about 12 times. at that point the use life of the plastic is probably done.
If anyone has spent cartridges they don't plan on repairing of any kind I'll gladly take them and recycle them. DM's are open.
