World Health Organization (WHO) advice on air conditioning and infection control on poorly ventilated non-ac buildings affect air quality and can contribute to the spread of disease.
Filtration Systems Installation & Maintenance
Microorganisms, such as those causing tuberculosis and legionnaires, can be transmitted by air conditioning systems, particularly when they are poorly maintained or when the number of air exchanges per hour in a room is insufficient.
Filtration systems can be installed in mechanical ventilation to stop those harmful microorganisms, particulates, gases, odors, and vapors, so they can be removed.
Increase In Air Flow
An increase in air flow and ventilation where the climate allows (opening windows and doors and using air conditioning for higher air exchange rates) will help combat this.
REFCOM Statement
There is no scientific evidence to suggest this is the case. Educate clients about any airborne contaminants that can be minimized, if not eliminated, by proper and effective filtration and regular cleaning and maintenance of ventilation systems.
