New Nano water mist system technology claims to clear nearly all ultrafine air dust
KAIST researchers promises to clear nearly all ultrafine dust with Nano water mist system
In a remarkable development, scientists at the Korea Advanced Institute of Science & Technology (KAIST) have unveiled a new Nano water mist system technology that claims to remove nearly all ultrafine air dust using self-generated nano-sized water droplets.
The Nano-powered device combines water electrospray engineering with a Nano sponge-like structure that autonomously absorbs and circulates water, eliminating the need for traditional filters.
Led by Professors Il-Doo Kim and Seung S. Lee, the KAIST team designed the Nano-based system to remove dust particles as tiny as PM0.3, nearly 1/200th the width of a human hair.
Unlike conventional air purifiers, the Nano mist device produces no ozone, requires no filter replacement, and operates on ultra-low power, roughly 1.3 watts.
Tests in a controlled chamber showed the Nano system removed 99.9% of dust particles between PM0.3 and PM10 within 20 minutes, including 97% of the most difficult ultrafine dust within just five minutes.
Notably, even after 30 repeated tests, the Nano device remained stable with no performance drop.
As the world searches for cleaner, safer air purification solutions, KAIST’s Nano water mist system technology could mark a major shift toward quieter, filter-free and highly efficient dust removal.
