Respirator w/ Filter Adaptor Mk.2 A respirator design that can accommodate your material of choice as the filtration unit. Each conventional surgical mask can be cut into 4 filter "discs", effectively increasing each mask's life span by 5 times. Inlet of the filter shroud diverts airflow by 45 degrees, further lowering the chance of contact by aerosol coming from the front side. External surface of the filter can can be disinfected by directly spraying 70% ethanol/isopropanol without damaging the hydrophobic property of the mask. The size and shape of the filter can have been optimized for ease-of-use and aesthetic purposes. Disclaimer: By CC BY-NC 4.0, you may not use this design for commercial purposes.
