Paper Mask Project

WARNING: This design does not protect against COVID-19!
DIY Paper mask project

"Five years ago, people would have laughed at the idea of a paper straw.
But right now, it's saving our environment."

I’ve been working on the idea to make a DIY face mask out of paper. It fits on a sheet of A4 paper and is fast and cheap to make and can be made at home with basic tools.

It's maybe too easy to say that paper is useless as a base to create face masks. Times are changing and we see more and more examples of paper replacing disposable attributes to contribute to a cleaner and sustainable environment. Paper is cheap, fast to work with, compact to carry, stack and available for everyone all over the world. The benefits of paper as a base are too big to ignore. And therefore, the challenge should be to create a useful face protecting mask that is available for everyone in the world.

This idea is why I challenged myself to design a face mask model that is made out of paper.

Engineering a fitting protective mask is a challenge and my design is just the start of this idea. I'm sharing this concept "open source" because I'm hoping that others will develop this idea into a useful alternative for basic face protection. With the right fit, the 3D paper design I have made seals the face for about 90% and filters air while inhaling. It's not completely sealed and leaking breath while exhaling but it's a better sealing compared to the more basic face protection that is used in healthcare all over the world right now. For example the classic harmonica model. mask types

My goal with this project is to contribute to free and cheap alternatives for a face mask that offers the same protection as basic (non-professional) face masks but is easy, fast and cheap to produce.

WARNING: This is a concept, it's not tested and totally experimental.

Updates:


03-28-2020: Just got very positive feedback from doctors that have tested the design. They are going to consider using it in the or as alternative protection. For non-COVID usage, to be clear. That’s great news and I hope this will happen soon.

03-28-2020: Professor Alejandro at the University of Lima, Perú and his team are going to see if they can improve the mask design, create a filter and test it within the university facilities. Looking forward to the results!

Why I want this to be tested and compared

COVID-19: WHY WE SHOULD ALL WEAR MASKS — THERE IS NEW SCIENTIFIC RATIONALE. The latest biological findings on SARS-Cov-2 viral entry into human tissue and sneeze/cough-droplet ballistics suggest that the major transmission mechanism is not via the fine aerosols but large droplets, and thus, warrant the wearing of surgical masks by everyone.

Questions and feedback to improve the design

There's no way that this mask/filter will block a virus
That is correct. This mask is not designed or tested to block COVID-19 (!). Right now, the idea is to maybe, one day, use this as an alternative for people who wear masks in non COVID-19 environments. It's being tested right now and I will update about the results when I know more.

Can I share/modify your design?
Yes, you can but please be careful and add a warning to your post that this is experimental, a project in progress and that it's functionality has not been tested yet. It's dangerous to give people a false sense of security. Please read pages 1 and 2 of the template file for more information about this project.

Can I wear glasses with this model?
Yes, you can. But it's important to wear the glasses on top of the mask (it's designed and tested for this to be possible). Do not wear glasses in the gap between the eyes and mask. It's less comfortable and also pushes the eye protection down, and creates unnecessary gaps that distort the seal and skin connection.

Can it be designed with an option to replace the filter?
Because the design of this face mask is based on paper as a base material, it's not wearable for a longer period (30 minutes max?) because breath will weaken the paper over time. This concept is designed to be disposable.

Is it better to locate the filter hole lower, higher, left or right?
The location of the filter hole is below the mouth and lips so the lips can not touch the filter. When placed on the cheeks, it's possible that the hole gets blocked and the leakage of breath on other locations will increase. There's also a vertical airflow for both nose and mouth with the hole positioned below the mouth, depending on the size and fit.

Can the eleastic cord be attached to just the ears?
Yes, that's possible. I’ve designed it for two straps going around the head but I think both ways work except, from my experience, the two bands going around the head pull and stretch the mask better so it seals more.



In the news (related info)

Researchers found that surgical face masks, made of a specialized paper that is both strong and breathable, were roughly 89 percent effective at preventing sick individuals from transmitting virus particles that are .02 microns (or micrometers) in size, which is five times smaller than the coronavirus. Meanwhile, particles 1 micron in size, 10 times larger than the coronavirus, were filtered at a rate of 97 percent.
