Mask with Filter Box

thingiverse

Updated Mask MKII with Filter Box Two sizes are available, one for men (larger) and one for women (smaller), each designed with its own specific filter box. The mask features a convenient filter box that can be easily swapped out, complete with an internal cover that has a secure grip to facilitate the extraction and exchange of filters. To ensure a secure seal, I recommend attaching the filter box externally with adhesive tape. Please note that this mask information is provided as research only, and its commercial use has not been tested. The design and masks created from this design have also not been tested or approved by FDA, OSHA, or NIOSH standards. This project was made possible thanks to the interest and contributions of the Lions Club Vallecamonica in Italy. I encourage you to share your own mask designs with us!
