Agnirva Space Premier League - Expedition #30133: Keeping Air Clean in Space: The Airborne Particulate Monitor Project

In space, even tiny particles can pose big health risks. That’s why NASA developed the Airborne Particulate Monitor (APM), an advanced sensor system created by ZIN Technologies and Aerosol Dynamics, under the guidance of Dr. Claire Fortenberry from NASA Glenn Research Center. This device has been flown on several expeditions including 63 through 69 and 73.

The APM continuously measures air quality aboard the ISS by detecting and analyzing airborne particles—such as skin flakes, fibers, and microscopic debris. In microgravity, these particles don’t settle but float, potentially being inhaled or contaminating equipment.

By monitoring the size, count, and types of particles, the APM helps maintain a safe environment for astronauts. It also provides data to improve spacecraft air filtration systems and informs future spacecraft designs. The technology is compact, automated, and able to function long-term with minimal crew interaction.

The same technology can be adapted for sensitive environments on Earth, like hospitals, clean rooms, and even aircraft cabins. It’s a great example of how solving problems in space can lead to innovations that benefit people here on Earth.
