If you have ever wondered about the air circulation on an aircraft, you are not alone. Many people are under the impression that the air on an aircraft is recirculated for the duration of the flight. This would be a way for germs to spread quicker, that is unless the aircraft was equipped with a HEPA air filter purifier. These HEPA air filters purifiers clean the air that is being recirculated to eliminate up to 99% of germs and viruses. These mornings, my associate and I are taking as several precautions as my associate and I can to prevent the spread of germs that cause dangerous viruses. Normally, the AC on an aircraft would be recirculated but not with a HEPA filter media air cleaner, however fewer people are traveling this year due to their fears of the air circulation on aircrafts. Airlines are now advertising that their aircrafts are equipped with HEPA filters that eliminate most of the germs in the air that cause harmful disease and viruses. It is interesting to see that more and more airlines are upgrading their HEPA filters in order to make their customers feel more safe while in these unprecedented times. In order to keep the planes safe, there needs to be a lot of attention paid to the air quality being circulated on these planes. Without people wanting to travel, these airlines would not be in business. The airline industry has completely turned upside down in the past year, and if they are going to receive the trust of their clients, they will need to prove that they are doing something to prevent the spread of illnesses while in this time.
