Joining Forces with Balvi for a Clearer Future

At the heart of Air Support Project lies a commitment to making clean air accessible to everyone. To further bring our dreams to reality, Air Support Project is proud to announce that we have received a grant from the Balvi Foundation, an organization initiated by Vitalik Buterin that focuses on funding high-impact, open source COVID projects. This collaboration epitomizes the project’s ethos of collective effort and high-impact outcomes, and has given us a jump-start in further developing a prototype for a portable air filter that uses multi-pass filtration technology to achieve the high Clean Air Delivery Rate (CADR) necessary for COVID-19 prevention that is difficult to achieve affordably with traditional HEPA purifiers alone. 

In order to extend our reach and better fit our mission, we are reincorporating as a 501c3 Nonprofit Organization.

Clean Air for All: A Sustainable and Democratic Future

Drawing inspiration from the DIY community, particularly the highly effective DIY Box Fan Filter (See Figure 1), Air Support Project has recognized an industry-wide need to transition from costly traditional HEPA purifiers to the more affordable and efficient fan-and-filter models

By combining the modest filtration of MERV-13 filters with higher flow rates, these devices optimize air cleaning and provide a greater CADR-per-dollar than any HEPA purifier on the market.

There is substantial evidence for fan-and-filter air cleaners’ effectiveness in removing infectious particles from the air, and regulatory bodies such as the CDC and NIOSH have recommended these homemade devices for combatting COVID-19 and wildfire smoke. However, other bodies, such as the EPA, have not adopted this model of air cleaner due to its DIY nature – instead opting for conventional-but-expensive air purifiers currently on the market. Our organization sees this as an opportunity to close the gap and spur widespread adoption of highly-effective air filtration technology.

Beyond DIY: A Vision for Accessibility and Education

Recognizing the need to make this revolutionary technology more accessible, our engineers at Air Support Project have created our first open-source prototype, with the goal of providing individuals and institutions (ie. schools) an off-the-shelf, tested fan-and-filter-style air purifier at an affordable price point.

Pioneering Progress: From Open Source Prototype to Production

Currently, the project has made significant strides with a single-fan prototype, and we are now engaging with manufacturers to explore potential production avenues. This prototype was built to verify that a 16” x 16” footprint and 14” diameter fan would have acceptable performance. Our measurements indicate an approximately 630 CFM CADR with 55 dBa noise at 1 meter from the unit. We hope to develop a manufacturable design based on the core features of this prototype, at an affordable price, with a goal of further reducing the noise level with refinements to the fan and housing. This is the kind of transformative, cost-effective solution Air Support Project is aiming to bring to the masses.

Know Better, Breathe Better

But it’s not just about the product; it’s also about empowering people. We have updated our website to include our open-source prototype hardware designs, as well as to provide free educational materials on mitigating pollutants like COVID-19 and wildfire smoke. Our first edition of Clean Air Times, a quarterly science, health, and lifestyle publication, is now available to download for free here

Air Support Project is opening doors to knowledge and innovation. We were proud to be part of the 2023 Clean Air Expo this past October, where our lead engineering advisor Mark Denning spoke alongside top industry leaders, experts, and innovators on the subject of creating a healthier, more sustainable future in the face of COVID-19. You can view his presentation: “Going Beyond DIY: Manufacturing the CR Box” here.

Invitation to Innovate

Air Support Project extends an open invitation to experts and enthusiasts alike. Whether you’re skilled in engineering, manufacturing, marketing, or sales, there’s a place for you in this visionary endeavor, and we invite you to contact us. Together, we can tackle the challenge of providing clean air – a fundamental human right.

Embracing the Future with Open Arms

As we embark on this journey, we remember the lessons of the past, harness the energy of the present, and embrace the possibilities of the future. Join us as we venture into a world where clean air is within everyone’s reach, where innovation meets accessibility, and where every breath we take is a testament to the power of collective action and visionary thinking.
