In the context that people are very worried about the spread of the Covid-19 disease when participating in vehicles, aircraft manufacturers have reassured that the special structure of the air filter is available. The aircraft has the ability to limit the spread of viruses in the air.
Currently, the aircraft are equipped with HEPA (High Efficiency Particulate Air) by the manufacturers of Boeing and Airbus.
The special structure of this membrane system removes over 99.99% of particles such as dust particles, pollen, human skin cells, bacteria and viruses with a minimum size of 0.001 micrometers.
The International Air Transport Association (IATA) said that the HEPA filter system fitted on the aircraft operates similar to the air cleaning system in the operating room, thus the risk of infection due to micro The bacteria and viruses on the plane are much lower than other enclosed spaces.
The World Health Organization (WHO) also affirmed that the use of HEPA filters on commercial aircraft will help minimize the spread of microorganisms in the aircraft cabin.
In addition, the cabin atmosphere is refreshed every 3 minutes; The airflow is designed to enter the aircraft vertically from top to bottom and circulate horizontally, contributing to limiting the spread of pollutants along the aircraft bay.
The aircraft of Vietnam Airlines such as Vietnam Airlines, Jestar Pacific are equipped with this air filtration system. In addition, the carriers are actively taking measures to: disinfect aircraft from China, Taiwan, Hong Kong, Macao, Thailand back to Vietnam and aircraft recording cases. guests with unusual health signs; adjust cockpit and passenger room temperature to 26 ° C; limiting the provision of meals, drinks, pillows, blankets, cotton towels on the flight.
