Like many people, i had the need to print in a closed space and the fumes/smell of the resin was a big problem.
I found on thingiverse an Air Filter that used activated carbon palets and a HEPA filter that looked great and decided to give it a try.... and ... It WORKS.
This filter system was made by RJ Maker and here is his links, i just made an adapter to fit it on to the anycubic photon:
The adapter was printed on an ENDER 3 with regular PLA at 0.2 Layer wight with 50% infill.
The white bit you see in the image is Super Glue i used to glue it all together.

In the end, this reduced the smell in my shop about 85% and i tested with Elegoo ABS like resin, Anycubic Transparent Green resin and Anycubic ECO resin.
Best of Luck
