I am trying to understand the fan and pressure design for a HEPA Filter. Can you share your understanding about filter designs (things such as flow through filter must be 0.5m/s, carbon has 0.2" mm H2O static and the fan static must be HEPA+carbon+CFM at that point etc.)?? Thanks!

PS: Currently I got a filter made from someone for my MK3S enclosure. But I would really like to learn these basics.
