Nano water droplet technology removes 99.9% of ultrafine dust in the air

Summary

A research team at KAIST has developed a water-based air purification technology that utilizes nano water droplets and a nano sponge structure to remove 99.9% of ultrafine dust from the air without the need for filters, according to Phys.org. The system is designed for long-term, quiet, and safe operation with self-supplied water.
