A panel filter isn't going to do anything at all really, well maybe for a short time.

To get anything really accomplished you would need a large amount of activated carbon, like a 50lb bag. Dunno what it would do for removing CO2 though, likely not much.

Like the pot growers use to keep the pot smell out of their exhaust from the indoor greenhouses, or in a smaller version what this guy made....

He used granulated carbon from a pet store for fish filters, probably cheaper to to go buy it from a water treatment dealer.

It'll help loads with smoke and it's odor but you still have the issue of the heater consuming all you oxygen and replacing it with deadly gasses.
