Covid 19 & Air-conditioning
“Any airborne contaminants can be minimised, if not eliminated, by proper and effective filtration and regular cleaning and maintenance of ventilation systems.
A clean ventilation system is an essential part of a healthy building and it is essential that any ventilation system serving a building where confirmed cases have been diagnosed are sanitised in accordance with best practice, and that any buildings where NO cases have been confirmed have their ventilation system cleaned to industry best practice as a preventative measure during this time and on-going.”
This information is our summary:
In short, the above simply means that if you have air-conditioning in your building ensure you have it serviced regularly as would normally be expected if you have air-conditioning.
