MASK COVID19

thingiverse

I use a mask for respiratory protection with an interchangeable filter, which mounts series 2000 filters but also other filters that you can cut out. I use particulate filters p3r. The mask is perfectly insulated thanks to the seal in contact with the skin, has two layers of activated carbon filters so as not to form condensation inside. I pass a layer of epoxy resin on the outside to plug any potential holes. There are three types of seals in the file, each with a different thickness for mounting various types of filters. https://www.amazon.it/gp/product/B077Y6XXG2/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1 https://www.ebay.it/itm/1-FILTRO-CAPPA-AI-CARBONI-ATTIVI-FILTRO-BIANCO-FINO-CM-47-X-57-UNIVERSALE/202624189727?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649 https://www.ebay.it/itm/1-Coppia-FILTRI-PARTICOLATI-MOLDEX-9020-P2-R/223894801807?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649 https://www.ebay.it/itm/Moldex-8080-P3-Rd-Particolato-Filtri-Harmful-Carcinogenic-Polveri-Fumi-Aerosols/123990511903?ssPageName=STRK%3AMEBIDX%3AIT&var=424797401465&_trksid=p2057872.m2749.l2649 https://www.ebay.it/itm/RESINA-EPOSSIDICA-TRASPARENTE-GR-800-BICOMPONENTE-A-B-DA-RESIN-PRO/253469075625?_trkparms=ispr%3D1&hash=item3b03ef28a9:g:tTAAAOSwC0Vc0ul9&enc=AQAEAAACUBPxNw%2BVj6nta7CKEs3N0qUe0Yeul7UANNQAuVkoW%2BEdwBDdTVC4DwsxmDbthSGhkM2oG8B99pw116UW4NM1Aj%2Fj3EYOpgH86eyTRk50WqSMe5texVolhZwZBeahTdRtgzTAhl6O6Ui60R9HEs1JTj%2FbOwz8h8rosVt5jXAPLkwb0rKvPnRv5b%2BUH%2BhWI5ERolo%2BhGeSGOAy9da0PHlYrefR6xhCFgppraVcfpl7OQXLqht5m%2BiSlifJMVxa5UWpM48hBPVNxTW4eDQx8uyCl%2BEdFt0cYI%3D&checksum=2534690756258406012549144475a55358c486a0cafc
