virus filter adapter for Decathlon, KHROOM, DIVELUX snorkel dive mask

thingiverse

This is my attempt to transform various snorkel masks (Khroom Seaview X, DIVELUX Snorkel Mask, Decathlon Easybreath) into a protective mask. No guarantee that it provides any protection against viruses. You can use your own filters from different sources, for instance non-woven polypropylene from a painter's suit. An o-ring 4 mm wide, 60 mm inner diameter (McMaster part number 9262K364) is required for sealing. Filters can be stapled to the disc to secure them in place. Other possible filter materials that may have an effect include: * A three-layer white special fleece by "Melitta" (https://world-today-news.com/corona-melitta-produces-breathing-masks-in-the-form-of-coffee-filters-2/). This fleece has a 98% filtration efficiency against bacteria. * Cotton pad as the first filter Check each mask version separately. I tested the tightness of the seal using water. See the video: https://www.youtube.com/watch?v=KVVVoFp11e4&feature=emb_logo In the video, I inserted two layers of non-woven polypropylene into my snorkel mask adapter. The polypropylene is from a painter's suit. Water level declines slightly, not because it passes through the filter, but because it flows into the hollows of the side walls (these hollows are designed to reduce printing time). My finger remains dry on the ground of the adapter. Use 100% infill.
