Here is what I am using in a 6'5" x 6'4 x 6' Grow Bay #1 and Grow Bay #2. I have used the equipment for many months without fail or issues and would recommend all.
I prefer to use a large carbon filter for maximum longevity of the activated charcoal.

If you are using the equipment in an area where humidity control is not a concern I would recommend the Titan Controls Mercury 3 - Day/Night Fan Controller to regulate the temperature of your grow tent. I have the temperature controller day set point just a few degrees below the maximum temperature of my grow area so the exhaust fan is able to operate intermittently and maintain the peak growth conditions in my grow area at 80°-85° Fahrenheit and set the night set point to minimum to allow the exhaust fan to run and remove any humidity from transpiration and ensure proper air circulation.
