Can airplane air conditioning systems filter Covid-19?
Travel has been significantly impacted by Covid-19 with flights being cancelled and travellers struggling to get home or travel for business.
In an ongoing study, researchers concluded that the virus does not spread as easily on an aircraft compared to wearing it other public areas. This is due to the way the air is circulated and filtered on the plane , as there is a high exchange rate it’s unlikely you’ll catch the coronavirus from someone several rows away. The study was carried out in late August at Dulles International Airport on a Boeing 777 and 767 Jets.
They placed a mannequin wearing a mask and unmasked in different areas and released fluorescent particles to mimic the virus. Tests were completed in the air and on the ground.They concluded that the virus was removed by the plane’s air filtering systems 15 times faster when compared to a typical home and five or six times faster what is recommended for hospital operating rooms and patient isolation rooms.
Commercial planes are equipped with HEPA filters, the Centers for Disease Control-recommended air filters used in hospital isolation rooms. These HEPA filters capture 99.97% of airborne particles and substantially reduce the risk of viral spread. In addition, the air in plane cabins is completely changed over 10 to 12 times per hour, raising the air quality above that of a normal building. Engineers at Boeing and Airbus also concluded that the risk of being exposed by the virus by someone seated next to you on an aircraft was about the same as from someone six to seven feet away in a classroom, office or store.
These cooling systems on planes need to be running efficiently more than ever for the health and wellbeing of staff and travellers. Our product Cryogen X4 enhances these systems by removing the oil fouling build up that migrates from the compressor and allows the refrigerant to flow faster. Allowing faster cooling, energy efficiency and decreasing running costs.
