carbon filter in room without external venting

is there any reason this wouldnt work? litterally just putting a carbon filter on a table in the grow room with the extractor fan just pulling the air through the filter and back into the same room rather than being vented outside the growroom?

i cant think of any reason this wouldnt work, just making sure before i purchase one (going to start flowering this weekend.) for various different reasons i wont go into i cant filter the air outside the room.

It will work.

nice simple answer, +rep

I cannot vent my air outside of my room either. Your idea sounds legit, let me know if it works. Thanks.

It's called scrubbing and people do it all the time. Hopefully you have a lot of ambient air and good circulation(fans).

cheers, i scrub too. using my old fish tank carbon filters reloaded, and placing them near fan intakes and on the chimney effect out of my closet. i drilled stoppers about 4 inches with a rock holding it closed for ventilation. place one on top and the carbon binds through adsorption while exiting air passes

it will work fine. I have a setup just like that, no problems as of yet knock on wood
