The first step in the fight against the coronavirus pandemic, mistakenly hardly ever taken into consideration in these historic times we are living through, is not the disinfection of indoor environments; if anything, that should be step zero, the point at which the conditions of an environment are returned to the lowest level of biological contamination. It is only at that point that all possible measures must be implemented to fight the threat of new contamination.
The first real step is the deep cleaning and disinfection of HVAC systems.
But why is it so important to maintain and monitor the condition of HVAC systems?
An HVAC system, from the simplest domestic split unit to the most complicated industrial air handler, is always composed of a filtration system, thermal control system (heating/cooling) and air intake.
The mass of air introduced into the indoor environment where we spend our time must pass through all these systems and does so continuously like a river, a slow, invisible stream transporting and accumulating particulate matter, dust and micro-organisms, leading to “sedimentation” just like a river, where rather than pebbles and sand, all types of suspended materials build up, living and otherwise.
This process, as already mentioned, occurs continuously, up to a such a level of “sedimentation” that spores and all micro-organisms, including viruses, find a fertile breeding ground: this is the point where exponential growth can occur, and the more time that passes, the more the concentration of microbes increases as they reproduce, to the point that most of these colonies return from the internal surfaces of the systems to the air flow and are transported into the environment in ever-growing quantities.
This issue, as shown by the scientific evidence emerging from studies and meta-analyses, also concerns the spread of Sars-Cov 2, the virus responsible for the COVID-19 pandemic, as previously mentioned.
The pathway of the air we breathe on a daily basis must always be checked regularly, starting with microbiological checks and including regular maintenance of the entire filtration-thermal control-intake system. This must be done by people who are familiar with this problem and have been working in the field to fight it for years with experience, expertise and professionalism.
