It's in the Air we Breathe - Unfiltered

A frequent flyer's personal pollution measuring devices show clearly how the cabin air is contaminated - different aircraft type and different airline. 
Below videos show how at cruise level air pollution becomes harmful marking 034 for formaldehyde (HCHO) 0.229 mg / m3, for TVOC 1.046 mg / m3 and particulate matter (PM) at 2.5 001 ug / m3 during practically the whole cruise; air humidity is 29% and cosmic radiation 0.58 microsivert. During approach pollution rises marking 038 poor air quality, formaldehyde HCHO 0.323 mg / m3, TVOC 1,481 mg / m3, PM2.5 004 ug / m3, humidity of 28%. ( #1 December 2019 / #2 January 2020 /#3 and #4 November 2019).

Several videos taken by passengers of visible toxic fume contamination on their flights. (#5 , #6 #7)

Quote US EPA: "HEPA filters can theoretically remove at least 99.97% of dust, pollen, mold, bacteria, and any airborne particles with a size of 0.3 microns (µm). The diameter specification of 0.3 microns responds to the worst case; the most penetrating particle size (MPPS). Particles that are larger or smaller are trapped with even higher efficiency."

The filtering system appears to be "malfunctioning" on this aircraft, or the filters are old, not cleaned, not been exchanged in a long time: see 2 video #11 and #12 - or the aircraft has no filtering system? (many regional aircraft do not have a filters).
