How long would it take a 6inch 400cfm inline fan to exchange the air 10x10x7 room?

Big thanks purple

If you are wanting to know if 400cfm is adequate to exchange your room size, then yes it is. Your room would require about 235 cfm to clear your room once every 3 minutes. 400cfm with filter and short duct runs will be good.
