Airgle improves the air quality in PolyU Library

The Pao Yue Kong Library, located at the Hong Kong Polytechnic University (PolyU), is a state-of-the-art academic library serving the university community and the public. It is named after Dr. Pao Yue-kong, a renowned industrialist and philanthropist who made significant contributions to education and social welfare in Hong Kong. To ensure a fresh and comfortable environment, Airgle medical-grade air purifiers have been placed on each floor, increasing the indoor air exchange rate.

Airgle protects the library with powerful filtration technology

Airgle is placed in multiple areas within the library, including the 24-hour reading center, group discussion rooms, multimedia workshops, self-study rooms, study areas, and conference rooms. It utilizes advanced technologies, such as H14 medical-grade cHEPA filters, super activated carbon filters, and TitaniumPro photocatalytic UVC sterilization modules, to filter and decompose various air pollutants, including airborne bacteria and viruses. Tested in a Biosafety Level-3 laboratory, Airgle has proven to eliminate >99.998% of the SARS-CoV-2 virus, preventing the spread of COVID-19 in the library.

Airgle incorporates ultra-quiet technology, operating as low as 33 decibels during air purification. It ensures uninterrupted study and reading for students, continuously delivering filtered air and allowing them to stay comfortably in the library.
