That’s interesting. But still only a small % of the air would go directly from the nozzle to the carbon filter if only a small % of the filter is above the bed… I’m unhappy with where the P2S draws in air to the recirculating filter. The P1S sucks in air from the top for the exhaust filter, closer to the nozzle height.
On my H2D filter, I made sure the air is taken from nozzle height and not just recirculating air below the plate, to catch the high VOC/particulate concentration air
It’s looking pretty yellow and gross now:
At some point, I think I’ll put a large filter here I think, and either exhaust it out with a large fan or have it recirculate with the existing fan:
