Filters with the performance of twenty–40% are sufficient at the entry aspect. HEPA filters, which can take away particles of size >0.three μm with performance of >ninety nine.97% are used as the next-line filters close to the ORs, ICUs, burn wards and many others. Air through the HEPA filters flow unidirectionally (vertically or horizontally) resulting in number of airborne bacteria within the operation web page.
