When I went to the local supply they were out of carbon filters. There was this in stock and so far no problem and I smoke. I don't even vent external here. Sounds like your place might be larger being a garage. Try it on timer when fan is on every other hour.
I have a ozone generator that I run in the garage after I harvest to kill any bugs. Then I don't enter it for at least 12hrs.
But be careful when using ozone, that stuff damages your lungs and could kill you if inhaled at certain doses.
