ScienceLight-charged filters could make air purifiers and face masks last longer
Cell Press describes a proof-of-concept filter that uses light to generate surface charge for capturing airborne particles. The Chem paper reports filtration efficiency above 99% and anti-clogging performance.
TLDR
The Chem paper describes a proof-of-concept system pairing a light-responsive coating with a polypropylene membrane. The authors report that light generates surface charge to capture hazardous airborne particles, with filtration efficiency exceeding 99% and anti-clogging performance. Cell Press presents the filter as an approach to longer-lasting air purifiers and face masks.
