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

- hwillis 4y agoUnquestionably 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.
