The aero penalty, weight penalty, and production energy penalty likely outputs an order of magnitude more co2 every 20k miles than they scrub.

Unquestionably correct, at least in the US.
In the US, .855 lbs of CO2 are produced per kWh (in 2021). If that moves the car 5 miles (same as a Model 3), the car gets 26.3 miles per 4.5 lbs CO2. Since the car absorbs 4.5 lbs per 20k miles, it absorbs .132% as much CO2 as was produced by driving it.
If the filters increase the weight (and drag) of the car by .132%, then the extra consumption will cancel out the absorbed CO2. What's .132% of, say, 3500 lbs?
4.6 lbs. If the filters weigh more than 2.3 lbs, the weight of the captured CO2 will cause more CO2 to be emitted than is captured.
