The biggest risk when flying just might be the airport, boarding, and take off/landing experience. So the air inside them must be recycled, right? The volume of cabin air is exchanged every two to three minutes. The Series 700 has a small seating capacity of 68 passengers. These High Efficiency Particulate Air (HEPA) filters cycle the air every few minutes, capturing 99.97 percent of airborne particles, Keyes says. G3 250 80% Am < 90% Please be respectful of copyright. The Spruce / Sarah Lee. [Sorry, airlines I hate being such a Debbie Downer But, as noted in earlier reader comments, when the decision-making process includes evaluating the potential risk of life and death, consumers are entitled to have the most complete variables provided to them, and NOT just the inflight portion of their journey, which although the information can pass legal muster as being substantially correct, omits the portion when one is aboard the aircraft while its at the gate using PCUs, which, of course, without delays can be 15-45 minutes depending on the size of the aircraft and number of passengers aboard, and with delays can be up to 3 hours before tarmac rules take effect allowing passengers to deplane.].

Thank You, they are pricey, reading about them now. LinkedIn page. Aircraft while at the gate during boarding & deplaning typically rely on PCUs for HVAC (using their own APUs while at the gate means the air is coming thru the engines, which means fuel is also required for power. Until then, the PCUs, which are basically commercial grade HVAC units, typically use filtration rated as G4, which is not nearly the same as standards comparable to an hospitals surgical suite, as airlines are touting. Gravity causes the big ones to fall to the ground (or an armrest) quickly, but the smaller ones can hang in the air. Thats faster than they anticipated being able to accomplish it Arndt was amazed by how quickly the FAA moved on the certification.
