Large low draft HEPA Filter

I wanted a filter with high volume throughput while also having low draft speed. I used a large commercially available car cabin filter (VAG 1H0091800) that is fairly common. It as well as the needed 120 mm PC-fan fit very tightly, so no other mounting materials are needed. The video shows it powered with 5V so any old USB charger should do the trick. All components are either cheap or lying around anyway in any good household. The filter has two prepared points for screw mounts as well as openings for SKADIS hooks.Top exhaust has alignment holes for a possible additional shield to divert airflow as needed.
