Two Stage Filter Mask

thingiverse

This is a two stage 3D printed filtering mask. This is yet to be tested for use in case of Covid-19. You can print this at home and insert filter into the parts. Add soap water to the reservoir as shown in the video. A continuous supply of soap water flows over the filter in the first part, carrying with it any micro droplets and draining it to exit at the bottom. The air that passed through wet filter now enters through a dry filter near nose on inhaling. On exhaling air moves from the nose through the dry filter and through the wet filter at the bottom, finally exiting out. IMPORTANT: This model has not been approved by any regulatory agency yet. This is an improvement on already existing mask - https://cults3d.com/en/3d-model/tool/covid-19-mask-easy-to-print-no-support-filter-required <iframe width="560" height="315" src="https://www.youtube.com/embed/62_78ok3g4I" frameborder="0" allow="accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe>
