Air conditioning and ventilation systems can contribute to exacerbating the risk of airborne infection.
As Per the latest research, a series of recommendations, both in the home and in the workplace, to maintain a good level of indoor air quality.
- If the rooms are equipped with autonomous fixed heating/cooling systems that do not supply new air from the outside but use, with recirculation, always the same internal air, it is advisable during use to open windows and balconies for a few minutes several times per day, to dilute/reduce the concentrations of specific pollutants (e.g. volatile organic compounds, PM10 particulate matter, CO2, odors, humidity, and biological aerosols).
- Pay attention to relative humidity levels above 70%, because it can favor the growth of microbial contaminants (bacteria, viruses, parasites, molds).
- Even the dust captured by the filters of the appliances represents a favorable environment for the proliferation of bacteria and fungi and biological agents
- If you use portable dehumidifiers, it is advisable to thoroughly sanitize your hands and regularly clean the components before and after use.
- For all appliances, it is advisable to regularly clean the ventilation grilles with cloths moistened with soap and water, or with an ethyl alcohol solution.
- Disinfectants (e.g. ethyl alcohol, sodium hypochlorite) are effective if dirt and dust are removed first. Excessive and repeated use of cleaning products can cause respiratory irritation and dermatitis making you more vulnerable to bacteria and viruses.
