HEPA filter cleaner

Use of a portable HEPA filter cleaner in a room is believed to be capable of reducing the risk oftransmission of infectious diseases through removing the particles or large droplets to which pathogensare attached. It is hoped that the portable HEPA filter(s) can increase the effective air change rate (forparticle removal only) in a general ward to the ventilation standard of an isolation ward for emerginginfection diseases when there are insufficient number of isolation wards.
