Transparent Reusable Face Mask

Vacuum formed and 3D printed transparent face mask with replaceable filters and an excellent seal.

I've made and donated over 1000 opaque 3D printed masks that have been fit-tested and and particle tested with great results. Using the same shape and fundamental design, I spent 4 months designing a transparent mask that fits better, has more airflow and better filtration.
