Canister filter ?

Are all can filters pretty much the same thing? I recently just finished a grow at my new place and could smell it outside with the canister filtering, summer is coming up and i think it will possibly get worse with the warmer temps. Thanks in advance!

If you can sitll smell it, then your can filter's carbon is used up, or more than likly you don't have the proper fan hooked to it. all filters have a cfm rating to scrub the air. I believe the air needs to contact the activated carbon at least.01 seconds to be effective.

But I am a stoner what the hell do I know...........
