MERV 13 is not nothing, but the bigger question I have is what is wrong with the system if CO2 is still going really high (I haven't personally measured this mind you). If it was blending significant fresh air, the CO2 would stay reasonably low. My guess is that the amount of fresh air is a configurable parameter, possibly even depending on outdoor conditions.
According to VIA (again based on what I've seen on-line) CO2 levels on its trains do not exceed permitted levels.
Trains are also intended to arrive on time. I would trust the people who have actually measured the levels more than Via in this case.
