Take Note of how it is secured in place so that you can add a PVC fitting without disrupting the re-installation, then remove it. Mine had two, easy screw on fittings, one at each end. It had a simple plastic strap around the middle where it sits in a cradle.
Take it to Home Depot. Buy a male and female threaded fitting of the correct diameter (2" on mine), and PVC cleaner and glue.
Go to a pet store and buy "Premium" activated Charcoal. Premium chunks are bigger and will allow better air flow. The crushed ones are cheaper but may cause a block if you allow one extra flush to foul it. Get some foam or aquarium filter material to plug the ends with.
Test fit the PVC fittings together and measure the distance inside that represents how much longer the fitting would make your filter (if making it longer will affect being able to put it back in) (seat to seat inside the fitting - 2" on mine). The connection on one end of mine goes right into the holding tank. On the other end, the vent hose turns 180 degrees after the fitting. Making the filter 2" longer could cause that line to bind or it may be too short. Making the filter too long could increase air resistance. Any blocking will cause the holding tank to blow up, potentially. That would smell bad.
Cut your filter in half where the fittings will not affect your re-installation. Cut out the extra amount as determined above if making your filter longer will affect reinstalling it. Clean it out, and let dry. Take note of fouling to satisfy curiosity. Remove label where gluing will occur. Sand both sides of both glue joints. Test fit parts. Clean with acetone. Apply PVC glue. Fit ends. Allow to cure.
Cut foam/filter material to fit in ends. Stuff that into the ends to hold the charcoal in. Fill both ends with charcoal. I put a thin piece of plastic over one end to turn it over to mate the ends. You'll need to leave enough room to screw the two halves together without compressing the charcoal too much. Slide the plastic out. Screw together. Check length. Blow through one end and ensure no blocking.
Reinstall. Smell the roses.
Next time, take charcoal and foam to boat. Take out, unscrew, dump out, replace foam and charcoal, and put back in. In my boat, this will take about 10 minutes and cost $5.
Today's expenses. $13 for charcoal, but used about 1/2. $3.50 for fitting. Already had foam and PVC glue.
