the claim

Food crumbs on the International Space Station can clog air filters and ventilation systems because they float in microgravity instead of settling.

Is it true that food crumbs on the International Space Station can clog air filters and ventilation systems because they float in microgravity instead of settling?

Unclear. NASA material indicates bread crumbs are avoided on orbit because tortillas, unlike regular bread, don't create crumbs, and a peer-reviewed review confirms HEPA air filters are used aboard the ISS. A ventilation study confirms microgravity prevents natural convection, requiring forced airflow, but none of these sources states that food crumbs actually clog ISS filters or ventilation systems.
