I thought that ERJ-145s dont have that capability? The very smallest of particles collide with molecules of gas, which slows them from passing through the filter and increasing the chance of their becoming trapped. The coronavirus pandemic has reminded us that having access to clean air is a global health priority. Maybe thats what the airline had in mind .toxic anti viral that was also dangerous for passengers. Molekule Tri-Power filters meet HEPA standards. Once the url clears for publication, the presentation format will be much easier to follow and the gigantic canyon between G4 filtration standards and the H (or U) for HEPA and higher (E is High Efficiency) will be readily apparent, especially since there are other classifications in between G4 and the E gradations, including F5 thru F9 and M5 and M6. Heres why each season begins twice. Photo: Getty Images Southwest said, "we equip each of our aircraft with a HEPA (High Efficiency Particulate Air) filter, which filters out recirculated air onboard each plane to remove airborne particles.. The air quality for aircraft while at the gate using PCUs can be upgraded to the same standard airlines (and their trade associations) are describing for inflight (high rates of top/down refreshment/recirculation using HEPA filters). Weve known since early on that it happens, but its rare, primarily because of hospital grade air filtration. There are two other EXTREMELY important reasons why COVID-19 is not easily transmitted on planes. "The HEPA filters are 99.9% effective or greater in removing particulate contaminants, including viruses like COVID-19, and bacteria and fungi from recirculated air. Each U.S. airline has implemented its own mask rules (here are Americans, Deltas, and Uniteds). is available ONLY while inflight. Great piece, this is worthy of mainstream journalistic outlets like Reuters, AP. Typically the number of particles in the air are [sic] really low, the plane is almost a clean room, because theres so much ventilation, and very few sources of particulate generation within a plane, says Liam Bates, CEO and co-founder of Kaiterra, an air-quality monitor manufacturer. While theyre still in contract negotiations with local machine shops and welding facilities, most of the work to retrofit the planes with HEPA filters will be done in-house. Hi. I'm not trying to open a debate on what you believe. Most people have never heard the term fume events, but the aviation community has been studying these phenomena for years. 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. LinkedIn page. Thank you for the feedback. Today HEPA filters are used in a number of devices, including air .

Such confidence is echoed by the industrys global trade organization, the International Air Transport Association. The latest aircraft to get a major overhaul is Bombardier's workhorse CRJ900, a . Given the relative importance of HEPA filters, compared to surface cleaning, this project has the potential to trump a lot of what other carriers have done so far. Anyhow, I know this is a bit longer than Cliff Notes, @cr, but its a complicated subject that does not exactly lend itself to a few short paragraphs! Crowded airports and stuffy jet bridges do not have the same air circulation as HEPA-grade air filters, Freedman said. More news. American Airlines too, said that the filters have been used on their entire mainline fleet,. The regional aircraft leased from ACIA Aero Leasing is configured with 50 seats in a single-class layout. insects Airplanes arent hermetically sealed environments, he explains. of ASHRAE test dust Average Efficiency(Em) The PCUs on their own do NOT currently allow for HEPA grade air quality being touted by airlines; b.) Again, I know this sucks but, unless and until our society universally embraces proven scientific knowledge such that wearing a proper mask is understood as being for EVERYONEs (including ones own and ones own family) best interest instead of being dragged into a culture war and instead becomes comparable to actions (and results) seen in countries and regions where infection and mortality rates are substantially lower than whats seen taking place in the USA, Brazil and Russia or of course a proven vaccine becomes available and it pains me to say this, but ALL of the factors involved with travel, and NOT just the time inflight under the optimal scenarios presented by airlines when HEPA filters and high/rapid rates of air refreshing/recirculation are taking place, must be included in ones evaluation of their own, and their loved ones who theyll come into contact with after flying (with presenting symptoms evident or worse, asymptomatic) risk tolerance and decision-making. We all want to get back to travel, but it would be better if we all survived too. They also have HEPA filters on all mainline aircraft and most regional jets that refresh the cabin air every two to four minutes. d.) Again, the air quality while the plane is at the gate can be upgraded to the HEPA standards and refresh/recycling rates used while inflight, but the operative phrase here is CAN BE UPGRADED which means: i.) A fan pushes air through the filter, and particles get trapped inside. On a CRJ700/900 there are recirc fans that take the some cabin air and mix it back with air from the packs. The Manhattan Project used HEPA air filtration to limit the spread of radioactive material. You didnt find an article about it? 1.)

HEPA media filtration bags function the same as HEPA filters. What if we could clean them out? Most airliners recycle 25-30% of the air in the. Again, its abundantly clear that the G4 filters in use when the aircraft is at the gate and using preconditioned air is VASTLY DIFFERENT than the standards being touted in marketing campaigns for the state of the art HEPA filtration used inflight. Delta Air Lines | SkyMiles - Do DL CRJ's have HEPA filters?

Thats one reason why Ive suggested staying away from small planes during the pandemic. 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. Thats both because of masks proven protective qualities and the fact that HEPA filters and rapid-air circulation dont work at max effectiveness until the plane is airborne. They spread into commercial use in the 1950s to catch viruses, pollen, bacteria, and other particles in the air.

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.
