Application of sterile medical air technology combined with middle efficiency particulate air filter in sterile wards

Applies UVGI air sterilization combined with middle efficiency particulate air filter to sterile wards in a hospital. The test results show that the system can reach the same or even higher air sterile standard than that using H14 HEPA filter. This system also corresponds with the national air sterile standard of the laminar flow wards, has low operation cost and it can replace the HEPA filter technology in leukaemia ward.
