Even if an airline changed filters less often than recommended, the International Air Transport Association says air flow through the filters might be reduced but their particle-trapping capacity would not. 0.3 m (micron) All of the above at a greater efficiency plus all smoke particles, fine dust, and most allergenic fragments. HEPA filters are mechanical filters capable of filtering and trapping 99.97% of all particles of 0.3 microns or larger in diameter. Notify me of follow-up comments by email. Because of these onboard filters, researchers have found that airplane air is as clean or cleaner than the air in offices, schools, and other indoor settings, Keyes says. but *NOT* when aircraft are at the gate during boarding, pre-departure dwelling & deplaning (which is when passengers, often toting carryon bags & searching for available overhead bin space to stow their hand baggage or placing them beneath the seat in front of them, etc., are clogging aisles & moving about the cabin that most experts believe is the period when risk of Covid19 transmission is highest) & ventilation is provided by entirely separate (& significantly less capable/robust) equipment called Pre-Conditioned Air (or PCA) Units, that do NOT: refresh in-cabin air nearly as rapidly using the same intense top/down diffusing & venting as that during inflight, or even HEPA-rated filters (typically, theyre G4, except for airlines such as United & Delta, both of which already announced changes of varying degrees to better narrow the disparity between the exceptional air quality available inflight & that provided during boarding, pre-departure dwelling & deplaning using less hearty, lower filter rated PCAs) as also used inflight. [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.]. While Delta, Alaska, Hawaiian and Jet Blue are, for now, keeping middle seats empty, any resulting COVID protection is likely from fewer people on board, not whether a stranger is sitting a few inches rather than a foot from you. By the way Singapore Airlines uses HEPA filters, too. They should put them in any method of mass transit. But some experts have expressed more doubt about the ability to completely scrub the air for zero chance of spreading flu and COVID.

These animals can sniff it out. However, the for purposes of illustrating the difference between aircraft ventilation during boarding and deplaning versus after pushback and inflight in this discussion, a PCU better resembles a commercial grade HVAC with filtration standards commonly rated as G4 for cabin ventilation on the ground before the process used inflight that includes use of the engines while inflight and the HEPA filtration standards touted by airlines (and their trade associations) in their marketing campaigns. @Andrew I dont see the problem with referencing a prior discussion.

Gary Leff is one of the foremost experts in the field of miles, points, and frequent business travel - a topic he has covered since 2002. The fresh air from outside the aircraft is naturally free from any pathogens at the high cruising altitudes where airliners operate.

In this photo, microorganisms brighten up the Bay salt ponds with vibrant colors.

, The 'extreme cruelty' around the global trade in frog legs, What does cancer smell like? AHEAD PRO is a diagnostic system that consolidates aircraft data to optimize maintenance activities and aircraft performance. If planes get more crowded you increase the number of vectors, the number of touch points and other ways you may be potentially exposed even if the air is blowing in a favorable direction. Most planes (but not smaller regional jets and turboprops) have HEPA air filtration thats highly protective. The efficiency of these filters, perhaps counterintuitively, increases for even smaller particles. Each HEPA manufacturer recommends the maintenance schedule for their products, and most airlines change them more frequently. Getting to/from the airport.
