Danger Dust - What Else?

Ultrafine particulate matter, particularly particles with diameters of 0.3 micrometers or smaller, presents a significant health risk due to their ability to penetrate deep into the respiratory system and even enter the bloodstream. Traditional filtration systems, especially those based on synthetic materials, often face trade-offs between filtration efficiency, airflow resistance, and environmental impact. Wang and colleagues tackled this complex problem by developing a filter derived from naturally abundant biomass, thereby aligning high-performance air purification with principles of sustainability.
