Air Filter System to reduce ABS smell for enclosured printers

I wanted to reduce the smell when i am printing ABS, because i have no extra room for my printer. So i created this.

You need:
The filter: https://www.amazon.de/gp/product/B009NP64TO
The fans: https://www.amazon.de/Scythe-100mm-Gehäuselüfter-2000rmp-Stück/dp/B006A806CI
(optional) Fan y-cable: https://www.amazon.de/Neufteche%C2%AE-L%C3%BCfter-Adapterkabel-Verteiler-Stecker/dp/B012FXNR9K
(optional) To reduce fan noise: some kind of step down converter

Simply assemble all the parts as shown in the second picture. Then integrate it in the enclosure (aka make a fitting hole).

The system helps, but it can't reduce the smell to zero (i think this is close to impossible).
