Respirator Made from Common Household Items This DIY respirator is designed to be made using everyday materials found at home, including a bike tube, vacuum bag, filter, PETG, and some tape. The innovative part of this design lies in the bike tube seal, which uses accessible materials and adjusts easily to the shape of the face. A large filtration area allows for the use of a vacuum bag as a filter. The seal works effectively, but it is not suitable for children. It may also cause skin irritation after prolonged wear. This respirator is designed for casual use, such as light biking or moving furniture, and should not be relied upon in critical situations. Breathing through this mask is not perfect, especially during strenuous activities. However, it can be improved by using different filtration materials, such as a medical mask. Disclaimer: This design has not been certified or tested, and its effectiveness is unknown. Use at your own risk. PETG Parts The body of the respirator can be made from PETG parts, which come in two options: * UNIBODY: Made in one piece, providing a solid structure with minimal surface area for condensation. * MESH BODY: Printed in two parts, featuring a mesh design that adds vibration to the voice. Both caps are interchangeable and can be printed without support. However, they may break off during use, so it is recommended to use a brim. Clip 2X The clip system allows for easy attachment of other parts to the respirator. The bike tube parts can be used with other components to create a more effective mask. Bike Tube Parts One mountain bike tube should suffice for two masks. Wash it well before use and assemble the parts according to the instructions. Head Loop The head loop is made from a 60cm piece of bike tube, but can be adjusted to accommodate different sizes. The clips accept 1.2cm wide stripes, which can be doubled in the middle for added stability. Vacuum Bag Parts Place the mask body on the vacuum bag and use a pencil to capture its shape. Cut a smaller piece from the bag and attach it to the mask using two tiny pieces of tape. Secure the edges with additional tape for a good seal. Filtration Materials Other filtration materials can be used, such as medical masks or those listed in the provided link. Always seal them with tape to ensure a secure fit. This design is meant to be remixed and improved upon. The purpose of sharing this idea is to promote creativity and sustainability during times of crisis. Old bike tubes can be recycled using this design, reducing waste and promoting environmental awareness. Test video: https://youtu.be/67QGXg0WP84
