recirculating carbon scrubbed air

Can I recirculate my carbon scrubbed air back into the grow room. Basically instead of exhausting it straight out of the room.

I have a phresh air filtter and intake fan cooling my lights.

The carbon scrubber is separate (and seems I am just wasting cool air by exhausting it.) I just bought an ideal air 12000 btu portable ac, replacing an 8000 btu unit and am still having trouble cooling the room below 70, with the lights off.

I wasn't sure if I was exhausting out too much cool air.

Any help or ideas would be much appreciated-

why not just exhaust all of the air through the carbon filter?

Pull air inside room through the carbon filter--- and through the lights---- and out of the room?

yah u can do that it called air polishing
but u still need to exhust the air to drawl in fresh co2 for the plant .....unless u seal the room and supply with co2

It's 2 filters generally to scrub the air without exhausting it. When you exhaust through the filter you are setting up negative pressure which prevents leakage except through the carbon filter, absent that you need to scrub harder. My room is 8x10 feet inside of 15x20 foot space I think and I use 6 inch and an 8 inch filter. My room isn't sealed really I sealed the windows, doors and I have a wall a/c unit. I don't pull in any outside air because plenty leaks from the a/c unit but when I am running co2 I put a trash bag over it, and when I close the door it is a lot more pressure in there. So if you have a wall a/c you may notice your co2 gauge doesn't change when venting in fresh air, it's leaking there anyway lol

if you're just using the fan/filter to get rid of odor and not heat from your lights, vent it where ever you want, the only reason to vent outside your room is to dump heat
