A team of 20+ seemingly random people who had never met: spontaneously formed into a fast-paced, rapid deployment team—hell-bent on saving lives. We are engineers, designers, clinicians, technicians, molders, quality assurance, regulatory, business, etc. This collaboration was born out of helpfulengineering.org and is now being pushed forward with overall project organization through Open Standard Respirator, and Maskproject.tech .
Additional technical information is also available at the MIT Center for Bits and Atoms coronavirus tracking page here.
Immediate needs (contact us!):
Getting these first parts off the presses and tested is our most immediate need. Ideally working with some manufacturers who are able/interested in doing quick turn molds, pro-bono. Figuring internal costs for programming and machine-time are on the order of 1-2k/mold, and initial material costs <$200 for first articles and prototype quantities for testing. From there scaling and manufacture should come with customers.
We've designed all components for very simple, single-pull injection molds. We have designed the face-piece to be compatible with either LSR or TPE manufacturing processes such that we can rapidly deploy masks on traditional machines, but also leverage the superior mechanical and sterilizable properties of silicone.
We hope it's not much of an ask, certainly considering the hours and prototyping costs our volunteer engineering team is putting into the design effort. You know you want to help: it's a freakin' global pandemic!
Our ideal partners are vertically integrated manufacturers who can take ownership of the entire process; we are not trying to be in the business of making masks, but rather trying to address current supply issues with a design that can better leverage available resources.

We aim to satisfy the four primary criteria of front-line healthcare workers: particulate and bacterial filter efficacy, breathability, and liquid protection.
- Bacterial Filtration Effıciency—ASTM F2101
- Sub-Micron Particulate Filtration—Determine particulate filtration efficiency as directed in Test Method ASTM F2299. Applied at 35cm/s air velocity.
- Resistance to Penetration by Synthetic Blood—Determine synthetic blood penetration resistance as specified in ASTM F1862.
- Inhale/Exhale resistance, residual CO2 NIOSH
