Carbon filter

If i have a can of carbon filter , should i have a fan blow in it or out of it

and is it any good in your experience ?

you have the fan pull air through the filter

yah, i agree, you want the air to pull through the filter, this will force the stinky air through the carbon in which it will get scrubbed clean and should come out smellin much better... if you have it the other way, its not gonna force any air through the filter and thus it won't do you any good..

Ok thank guys
