Germ Free & Odour Free Hospitals - a Dream or Reality?

Chemical Free Disinfection of Hospitals and Hotels

Hospital Acquired Infections (HAIs) are among the most common complications of hospital care, leading to high morbidity and mortality. While WHO estimates about 7-12% HAI burden in hospitalized patients globally, with more than 1.4 million people suffering from infectious complications acquired in the hospital at any time. The figures from India are alarming, with an incidence rate varying from 11% to 83% for different kinds of HAIs [Dr. V Ramasubramanian, Apollo Hospital, Chennai, Indian Journal of Basic and Applied Medical Research; September 2014: Vol.-3, Issue- 4, P. 46-63 ].

Two main mode of getting HAI is through contact and/or through airborne germs. The infection through contact (healthcare person to patient, patient to patient) can be controlled by proper housekeeping and good hand hygiene practices. The airborne microbes are difficult to control because it needs poisonous chemicals to kill microbes and the room need to be isolated during fumigation, the typical cleaning process or use HEPA filters.


Many methods are available to disinfect air in the hospitals:

Using chemicals

Poisonous and/or harsh chemicals are required for disinfecting the rooms. Therefore, rooms cannot be used during the disinfection procedure (patients need to be vacated). After the prescribed time of disinfection, the excess chemicals need to be purged out of the room. Thus, all the excess chemicals for the disinfection is released into the environment, some of which are even carcinogen. One handicap of this method is that when the patient returns to the room, the microbe count goes up which mean the microbe count will be cyclical.

HEPA filter

HEPA Filters are used widely by the hospitals to disinfect the rooms. These filters can only filter out germs/microbes larger than 0.3 microns. Although the germs are removed they remain alive and multiply on the filter. As they are alive there is a possibility of recontaminating the area. Yet another challenge is the maintenance of the filter because there is no way to determine when the filter is full or need change. In addition to that changing the HEPA filter (every two years or when a highly infectious patient was in the room) is an expensive proposition.


UVC can also be used to disinfect the air, but there are two handicaps:

a) Carcinogenicity of UVC
b) Limited working radius of UVC

Like the chemical disinfection, the microbe count will be cyclical.

Chemical Free Deodorization of Hospitals and Hotels

Bad odour generated through microorganism activity or other organic source is an issue that hospitals and hotels need to deal with. Most of the odour is caused by volatile organic compounds (VOC).

There are two different methods of odour control:
Masking odour control and Reactive odour control.

Masking odour control

Masking odour controlis done by spraying compounds/chemicals with a pleasant odour like perfumes to mask the bad odour. Here the odour is not eliminated but just masked by a higher odiferous compounds/chemicals.

Reactive odour control

In reactive odour control, the VOC's are reacted to form high molecular weight, non-volatile compounds, or the VOC's are oxidised whereby the odour is eliminated. The preferred method is reactive odour control and not the masking odour control. Viroblitz utilises reactive odour control technology by oxidising the VOC.
