The Importance of Air Filtration in Hospitals

Melissa Shea-Brooks

Hospital ImageA well-maintained air filtration system is crucial for all types of medical facilities. Problematic scenarios will occur if there are mechanical failures and/or disruptions. A medical facility's maintenance priority must be the ventilation systems. Due to a hospital's nature of contagions and germs, ventilation systems need to protect patients, doctors, nurses, and visitors from contracting nosocomial (contracted as a result of being hospitalized).

One Size Does Not Fit All

Not all parts of a hospital require the same filtration system. There are many units and many different required filters and ventilation systems. Areas of the hospital that deal with dangerously contagious patients absolutely need a higher efficiency system than areas that do not. Sections that do not deal with patients such as laboratories and autopsy rooms generally use a system that can filter out gaseous contaminants to keep the whole facility safe.Biohazard

Referring to the MERV rating scale, a 9 is the minimum efficiency value that is appropriate for hospitals. However, hospital filters may need more than that. Generally, the most appropriate filter efficiencies can range from 15 to 20, because you need a filter that captures the tiniest of particles, such as those found in air-borne viruses. Micro-fine fiberglass or synthetic media are common materials used in a filter with a higher MERV rating.
