built a intake box with a carbon filter housed inside it creating a suction pulled through the 6" hole on the side so all the outside air gets filtered and to keep a high flow through the room instead of pushing through the filters. room got to 78 today and outside temp was a warm day at 70 so i am thinking when it really gets cold i will be good. also it seriously silenced my intake outside before it sounded like a 747 now it is hardly noticeable lol.
