Purify the Air Supply

Has your time spent indoors increased during the COVID-19 pandemic as a result of stay-at-home and shelter-in-place policies worldwide? Your challenge is to use the International Space Station (ISS) as inspiration and develop a system to monitor and/or purify indoor air. It is entirely up to you whether the system you design is able to be used on Earth (for example in homes, businesses, transportation, etc.) and/or in space.

Clean Room Quality Power Air Purifying Respirator (PAPR)

Summary

Our PAPR (Powered Air Purifying Respirator), featuring 99.99999% filtration efficiency, is 500,000 times better than N95, 3,000 times better than other brand's PAPR. It can filter out airborne pathogens (bacteria and viruses), such as TB, flu, SARS, MERS, SARS-Cov-2...etc.. By wearing this clean-room respirator, no fear of Biological attack.It also can work with a CBRN (Chemical, Biologic, Radiologic, Nuclear) gas canister to become a combinational personal protective equipment (PPE), to protect particulate matters and gas (or vapor). It can be used in occupational health and safety market, hospital ICU, and protection from biologic terrorism attacks.

How I Addressed This Challenge

In ICU or negative pressure ward, millions of airborne particles (or virus) are floating in the air. Neither N95 (95% capture rate, fit-test performed before use) nor other brand's PAPR (99.97% filtration efficiency) can protect HCWs from SARS-Cov-2 attacks. Only 100% filtration efficiency PAPR can do, that is our device.

Our PAPR is the first revolutionary respirator which can be used by children, the elderly, pregnant and vulnerable group of people who are weak in health condition, this group of people can not use N95 due to its high pressure.

How I Developed This Project

We started first generation PAPR project in 2013. Shipped 3,700 units to China market in 2015. We are looking for seed fund to proceed our second generation PAPR which is light-weight, low cost, and high quality. The technology was ready in 2015. Hardware is mini51 CPU, Keil C program. The problem we have now is we need seed fund to get into mass production, and it may take another 5 months. All R&D problems were solved before 2015.
