The hospital is the place where in life is being restored and being saved. But ironically the hospital environment is also one of the dangerous places where in you can acquire diseases. The diseases that are acquired in the hospital are called as the nosocomial diseases.

Among the many infections that you can acquire in the hospital the airborne pollutants are the one that should be given much attention. Even the CDC (Center for Diseases Control) emphasized the importance of the atmosphere in the hospital that should be kept clean and safe not only for the patients but for the healthcare worker as well.

The problem starts because of the effort that the hospital is doing to save the air-tight in the hospital in order to preserve the energy. With this reason the air flow is decreased and the microorganisms are just around the corner in the hospital.

The poor quality of environment in the hospital can do a big thing with regards to the rehabilitation or the recovery of the patient. One of the best examples is the SARS problem in year 2002-2003. This shows the vulnerability of the modern hospital against the fight of airborne pollutants.

The good thing is that there are purification systems that most of the hospitals can use today. One of the system that they can use is the HEPA technology that purifiers the air in the hospital. The use of this technology will filter automatically the 99.97% of microbes in the hospital. The CDC have given this much attention after the incidence of SARS. There is also UV technology that is used as the final defense of the hospital against airborne pollutants.

Since the indoor air is in constant contact with the patients and the healthcare worker this means that there should be more attention with regards to air purifiers in the hospital.
