You might try it this way and see if you can get by with just one fan.

thats the way i waz trying to explane. exept a Y not a T. but they both work the same way. maybe put the fillter at the end of the line so that you get better air flow

using a T or a Y is inefficient. all of the air is going to be sucked in thru the side without the carbon filter because it is the path of least resistance. this means that very little air will be sucked thru the carbon.

passive intake = just a hole, no fan. you don't need fans at the bottom of the tent sucking air into the tent. you just need a fan at the top pulling air out. if you pull air out of the tent and have a hole at the bottom.. air will be sucked in else u will create a vacuum.

thats why you put the fillter at the end of the line right at or just b4 the exhaust hole.
