you also don't need 30cm clearance for exhaust, on a B1. About 20% of HEPA's fail from the factory to the customers final placement for many reasons. "They are good, they are fresh filters" doesn't cut it.

It is funny though, good work!

70% exhaust and 30 % recirculation is a class A2. This is horrible acting. The certifier didn't even take velocities or scan the hepa filters. Horrible.
