Self-charging Air Filter Face Mask

• A research team at the City University of Hong Kong (CityU) has developed an air-filtration face mask that is efficient, durable and low-cost. It isa breath-to-charge electrostatic face mask for prolonged air filtration at the same time capable of self-charging through the user’s breathing.
• This mask works through a Self-charging Air Filter (SAF), which leverages the triboelectric effect (i.e. build up of electricity by rubbing of two substances) and achieves efficient and prolonged airborne particle removal. 
• The SAF maintains a high efficiency of 95.8%.
