Airzone Air Purifiers for Odour control in Old peoples homes, hospital wards
Ozone deals effectively with problem odours in hospitals, nursing and old peoples homes. Unpleasant odours are a common problem in establishments caring for sick and/or elderly people. They discourage visitors, damage the reputation of the establishment, lead to unnecessary stress for visitors, residents and staff and increase the cleaning costs. The causes of the offensive odours range from repeated incontinence and vomiting (making soft furnishings difficult to clean effectively) to inadequate personal hygiene and poor ventilation. Due to energy conservation policies and the need to keep frail people warm, especially in winter, it is not usually practical to flush out the bad odours by using higher numbers of air changes. Artificial chemical fragrances can be used to mask the smell but this generally only makes matters worse especially in a badly affected facility. Ozone has been found to be highly successful in eliminating these unwanted odours in hospitals, nursing and care homes and provided the amount used is accurately controlled it is the ideal solution. Not only will it eliminate odours but it will also help reduce the moulds and bacteria that may exacerbate the odour problem. Fixed or portable ozone generators can be employed on an ongoing or as required basis to deal with problems making rooms smell fresh and pleasant for all users
Prevention of spread of Airborne pathogens and control
The air in buildings often contains potentially health threatening bacteria and viruses, particularly for people who have impaired immune systems. Tuberculosis, for example,is an infectious disease that can be contracted by breathing air containing the tuberculosis bacterium. To reduce the risk of transmission of disease, the air can be disinfected and controlled other microbial disorders such as influenza, measles, and aerosolized bioterror agents.
Tuberculosis or influenza is spread when a person who has tuberculosis disease coughs or sneezes, thereby releasing the bacteria into the air in the form of an aerosol. Persons inhaling these bacteria may become infected. . As a general principle, it is better to prevent infection from occurring rather than try to cure a disease after it has been contracted.
Purifying the air through UVGI (Airzone Calypso) destroys the infectious agents in the air because exposure to ultraviolet (UV) radiation damages the deoxyribonucleic acid (DNA) of bacteria and viruses, including that of Mycobacterium tuberculosis. This DNA damage stops the infectious agent from replicating. Air cleansing using UVGI requires that persons in the treated space be shielded from excessive exposure to the UV radiation. This can be done by placing the UV source in the ductwork of a ventilation system ( Airzone Gentle Breeze), in a freestanding disinfecting system, or in an open location within a room (Airzone Calypso). When installing UVGI in an open location, to prevent undue human exposure to the UV radiation, it is important to ensure that the UV radiation is restricted to the portion of the room that is above standing head height ( Airzone Sani Disc). The UVGI technology has long been used in laboratories and healthcare facilities, but it is also applicable for use in spaces where people congregate. These three approaches can be used separately or in combination.
Upper room UVGI is a common feature of buildings. Upper room UVGI (Airzone Sani Disc) is an effective method for cleansing the air of many types of viruses and bacteria, including some of those suggested as weapons for bioterrorism. The technology is well-developed and it can be easily retrofitted in many buildings.
