Gas Filter Not 100% Reliable

The line that goes out the top of the screen looks like it is coming from another source. Where does that line originate?

plus if you mouse before and after you will see what it is, the displacement means your not quite in the same cell as the CO2.  Save file please?

That goes to my Electrolyzer at the top of by base.

Can you post an image of the actual source of the O2 in that pipe? Alternatively, post the save file as Kabrute requrested (typically easier for people to help diagnose/fix and/or confirm).
