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. Regarding specific airlines (in addition to Americans upgrade to HEPA rated filtration for its Embraer 140/145 fleet discussed in Garys post above): On July 21st United announced it was upgrading onboard air quality for all mainline aircraft at the gate during boarding & disembarkation to match the exceptional ventilation featuring HEPA-rated filters beginning July 27th, thereby eliminating a disparity between inflight & when aircraft are at the gate; On September 10th, Delta announced it was upgrading the filters used by the PCA units to MERV-14 rated, which it says are 40% more effective than filters previously used, for more than 600 gates at its largest 31 airports, with unspecified other airports/gates to follow in the coming months; To date, while larger regional jets such as Mitsubishi (ne Bombardier) CRJ 700/900 models (including the 550 dual class 50 seater at United) as well as Embraer 170/175 (& mainline 190/195) also use HEPA-rated filters inflight only, the quick & dirty research done for this reader comment post does NOT indicate if any upgrades for ventilation of aircraft at the gate during boarding & deplaning is included with the above referenced efforts by United & Delta; other airlines (US domestic or foreign based) may have similarly acted to remedy/mitigate the disparity between onboard air quality available inflight & that during boarding & deplaning/disembarkation while aircraft are at the gate, as this reader comment is NOT intended to offer, nor should it be construed as providing a detailed, worldwide industry review. Googling something and not finding results does not make you a domain expert. 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. The HEPA filtration system can make a complete air change approximately 15 to 30 times per hour, or once every two to four minutes.

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. This Delta video shows a HEPA filter being replaced. [], [] Thats different from the extent to which the virus spreads from person to person while on the aircraft.
