lol 
ok I had a normal air intake over my window (as I have over all my windows)
its one of them small boxes wher you can open or close em .. just passiv ..
I removed the box and filters so I can see I have a opening thats like 2 inches wide and 15 inches long or so (also removed the netting from out side .. and then I fit some of the net from work (200 my netting) to keep bugs out ..
then I made a strain from it to my passiv intake so it could pull fresh/cold air in .. did work .. well more or less .. intake was a bit small and only passiv so had to have the same size hole in to my room .. so 2x 100mm holes ..you could say it got ½ and ½ fresh air and air from my appartment ..
now I removed the smallest part of the cardbord strain and replaced it with 100mm plastic tubeing .. and also got a cheap bathroom ventilation ..

just a 15$ one ... 100M3/hr .. to help pull the fresh air in and down the strain as it is like 4 meters long .. could still fell the fresh air comming out the strain before I fit it but even more with it on ..
