How many air changes per minute?

Hey guys,

How many air changes per minutes do I need with a carbon filter in order to remove all odor?

Some people say one air change per 5 minutes and some say 5 air changed per minutes.

I believe it to be once every three minutes

I thought as long as you have negative pressure

and you would be right. To fast and the carbon wont do its thing.

For odour it's a slight negative without over powering filter, check rating. For air exchange they recommend 3x a minute although I don't know why, that's a shit load of air changes. Temp management gets more complicated .
