Reduction in MRSA environmental contamination with a portable HEPA-filtration unit

The evaluation of the effectiveness of a portable high efficiency particulate air (HEPA)-filtration unit to reduce MRSA environmental surface contamination within a clinical setting, was the aim of this paper. Contamination rates have been measured at different air filtration rates (60 - 325 m3/h) and compared with no air filtration. It appears that this portable HEPA filtration unit can significantly reduce MRSA environemental contamination within patient isolation rooms and be complementary to existing MRSA infection control measures.
