American also takes extra steps to ensure customers and team members breathe clean air aboard our aircraft. What is a HEPA filter? To be clear, while inflight there is NO REASON to doubt the claims being made airlines (and others) about the rapid rates of refreshing; the top-down circulation provided by diffusers above and exhaust vents below; or the use of HEPA grade filters when the aircraft is taxiing and airborne, when the plane is at the gate, the ventilation system is more like a commercial grade HVAC than the hospital surgical suite caliber thats being aggressively promoted by airlines, IATA and others. But not all aircraft benefit from these measures while at the gate []. However DASH-8 turboprops can now be retrofit to have them. This model pulls from the top, I have it in a large part of my basement, no way to really tell how effective vs the IQ. This is both expensive [and much more expensive than the jetway mounted PCUs which use electricity, at that], plus of course, results in much higher carbon emissions vs electricity used to power PCUs); c.) Air quality for planes parked at the gate and using below jetway mounted PCUs can be upgraded from the garden variety G4 category used for commercial grade HVAC units to HEPA category filtration levels, but until then, the air quality during boarding and deplaning is NOT nearly as high as airlines are touting in the marketing hype. HEPA vacuums are recommended for minimizing dust, dander, and other common allergens in homes. Cleaning your hands with sanitizer onboard is fine, Fagbuyi says, but wash your hands with soap and water once you get off the plane, and especially before removing your mask. The problem is that without enforcement, the people who refuse to wear masks are also much more likely to have been the ones to engage in other higher risk behaviors. HEPA or high efficiency particulate air filters have similar performance to those used to keep the air clean in hospital operating rooms and industrial clean rooms. To its credit, five (5) days after the initial series of reader comments I began posting here on VFTW (on July 5th) plus several additional detailed critiques & analysis I posted in the reader comments section for posts, including very slick/polished video presentations/advertisements, made by the International Air Transport Association (IATA) on LinkedIn (& Twitter), as well as others on my LI homepage, on July 10th IATA *CONFIRMED* that its messaging, including that provided in its (informational) videos/advertisements touting exceptional onboard ventilation equipment featuring robust refresh rates, top/down diffusing & ventilation, & HEPA-rated filtration applied while inflight only, & therefore NOT when aircraft are at the gate during boarding, pre-departure dwelling & deplaning/disembarkation periods when PCA units are used. On a CRJ700/900 there are recirc fans that take the some cabin air and mix it back with air from the packs. I flew on a JetBlue Embraer 190 regional aircraft and was impressed by its plush, spacious seats. Cabin air quality featuring filtration comparable to hospital surgical suites using HEPA filters, plus high rates of top (of cabin)/down (floor venting) refreshing/recycling every 2-3 mins as airlines are touting) is guaranteed to take place only after the HVAC is provided by the aircrafts internal equipment and NOT by the preconditioned air units (PCUs; typically seen mounted below the jetway/jetbridge look for the big yellow and black ringed hoses) when the aircraft is at the gate during the boarding and deplaning periods.

For the non-hard core avgeeks (or those less familiar with Ground Support Equipment, or GSE) among us, Pre-Conditioned Air Units, or PCA for short, resemble, but are NOT quite identical (to allow for different environments deployed) to, conventional commercial grade HVAC units commonly used at office/commercial buildings whose refresh rates & filtration, typically G4-rated, are *NOT* nearly as robust & precise as the onboard ventilation equipment & HEPA-rated filters touted by the International Air Transport (IATA), industry leaders & widely cited/quoted in media reports that are powered up shortly before doors are closed & aircraft push back from the gate for taxiing out to takeoff. Planes, like most places, will never be 100 percent safe, Keyes warns. Simply put, until the aircraft ventilation is switched from the preconditioned air pumped in from the HVAC units mounted below the jetway at the gate (or pumped in from a mobile unit for aircraft parked at gates that use hardstands), the system thats being discussed in many marketing campaigns that uses the engine bleed and highest rates air refreshing/cycling is NOT even turned on yet, but instead, is more like the same type of ventilation in an ordinary room or restaurant than the magnificent and highly efficient HEPA filtered systems airlines are touting right now. When does spring start? Bear in mind that a single human hair has a diameter of. Can we bring a species back from the brink?

The overwhelming majority of people, including those with chronic lung and heart problems, can safely wear them, she says. These High Efficiency Particulate Air (HEPA) filters cycle the air every few minutes, capturing 99.97 percent of airborne particles, Keyes says. According to the International Air Transport Association, air filters can remove very small particles, such as bacteria and viruses. These filters are essentially sheets of fiberglass fibers, with diameters between half a micrometer and 2 micrometers, randomly arranged.
