Respirator mask with bike tube seal and vacuum bag filter

thingiverse

Bike tube respirator designed to be made from items commonly found at home. * Bike tube - seal * Vacuum bag - filter * PETG - body ... and some tape The inventive part of this design is the bike tube seal. It's made using accessible materials and adjusts easily to the shape of your face. The large filtration area allows for use of a vacuum bag as a filter. Seal works great, I've tested it on myself and friends. Not suitable for kids! Breathing isn't perfect - I did some light biking and it was okay, but when I tried moving furniture in it, it got wet and I couldn't breathe anymore. I believe this is the best you can get with vacuum bags. You can use different filtration materials like a medical mask, which would be a whole new story. **DISCLAIMER** This design is untested and uncertified. If you have certified protection available, please use that instead. Use this design at your own risk. After 5+ hours of use, it may cause skin irritation. **PETG parts** * BODY You can choose: + UNIBODY: printed in one go. + WITHmesh: printed in two parts with a mesh surface for better breathability and less condensation. - Adds funny vibration to your voice (may be a plus for some!) + BRIM is recommended to prevent breaking off during printing. * CAP You can choose: + Both caps are interchangeable, one is slightly cooler! + Printed without support of any kind.
