Lucas- I have the RS 5L HO Can Fan, mated to the 2600 CanFan filter, I couldn't be more pleased, it does a great job at getting rid of smell, I only use a 3' x 3.5' area inside a walk-in closet thats actually a huge closet... 3.5' x 8.5' and the ceiling is 7.5' , I have it mounted up at the ceiling and it pulls all the smell and even pulls out some of the heat. I have an Active Air 265 cfm squirrel cage fan that I screwed onto the top of the door frame blowing air in that I cut down and made the door shorter by 12" so I could nail a 2x12 board in its place with 2 holes...one in vent and one out vent. I can say that my squirrel cage fan runs extremely hot and it has no load on it, I still regret ordering it, my plan is to buy 2 more CanFans , one to replace my squirrel cage and one to put onto my reflector so I can use my glass lense with it. My CanFan never runs hot, doesnt even get warm, inline fans are the way to go, 2 of the top makers are Can Fan and Vortex, my Active Air squirrel cage will blister your skin if you put your palm on the motor for more than 2 seconds.
