Maybe you could sew a pocket onto the mouth/skin side of your mask for filter insertion.
Yes, that was my original thought was to make a frame where it would hold a replaceable homemade cutout of my vaccum cleaner bag HEPA filter material. That way I could keep the frame and just slide in new inserts whenever they get too used.
The problem I am having is trying to figure out a good frame. Those patterns look perfect so I may have to take a crash course in sewing. LOL
