hey guys im fixing to purchase either an 8 inch or 6 inch mountain air or phresh filter (still trying to decide which is better for odor control) and need to know how many cfms i should be running to accurately control odor. my exhaust pipe is 6 inch in a 4x4 tent with a 1000 watt hps. The problem is my fan is non adjustable and is rated at 440cfms. Should i get the 6 or 8 inch filter? Im still sonewhat new to indoor this will be my fourth grow. Thanks guys i really need the help.
