As long as both are matched to the room. Example... 5x5x7 tent. The area is 180 cubic feet (in eroupe im guessing it goes by meters) then you nees a fan and filter rated at least 180 cfm. Again make the filter biger than the fan but dont over do it. The fan has to be no more than 50% smaller. Example 150 cfm fan is good for filters rated 150-290 cfm.As long as your filter is bigger than your fan you're good to go. I run a 6 inch 360 cf fan and and 8 inch 750cf filter.
