An open source, disposable and flexible respirator designed for emergency use. Ships flat and folds like origami.
This respirator is not NIOSH certified or FDA approved. Please use your best judgement and discretion before wearing this mask and observe the guidelines recommended by the CDC and public health departments. We do not claim that this mask is guaranteed to keep you protected from COVID-19.
This device is currently in the testing phase at hospitals. Basic tests have been conducted on the current 65mm filter design and results from fit testing will be published soon. If you are a hospital or clinician interested in reviewing this design, please email basicrespirator at gmail for an evaluation kit.
A sheet of Tyvek™ or any other textile is transformed from a 2D flat pattern into a 3D form with a few simple folds, like origami. No sewing is required and the mask can be discarded after use.
The respirator ships and stores flat with preapplied adhesive. The mask assembles in minutes and the wearer can adjust it for a custom fit with an airtight seal. Tyvek™ is flexible enough to move with the wearer's skin so that facial expressions and talking won't introduce gaping or fog glasses. Because Tyvek™ is a lightweight and breathable material, the mask can be worn comfortably for long periods while performing strenuous activity without causing lightheadeness or sores.
A 3D printed filter assembly accepts an N95 or substitute filter. The entire assembly uses 9.5g of filament and prints in about an hour with no supports or cleanup. Depending on materials and printing technology, it can be discarded/recylced or sterilized between each use.
The materials below are recommended for those that work in healthcare. We will continue to update this section as materials are tested and results are published. Please read the Safety section and consult with administrators before determining their use.
Fold into shape using the adhesive tabs, add a neoprene strip and adjust for an airtight seal. Insert the filter assembly with an N95 filter and tie on the straps. The mask is designed to last for an entire shift and should be discarded after use.
