Bento box Hepa Switcheroo (P1P, P1S only!)

P1P-P1S only, this hepa holder is a bit taller than the regular one, risking potential collisions with the micro lidar on X1 models. not tested though, just a hunch.

Since the bento box is meant to suck air in from the top and expell from the bottom ive noticed fine coal dust in the exhaust port of the bento box from the pellets rubbing against each other. to prevent the box from blowing dust all over the place ive switched the hepa filter and activated coal filter position. the hepa filter cartridge is still a snug press fit for the filter cartrige, position the filter cartridge in the middle with some breathing room between the hepa and coal filter and fans, air flow did not change, but im also using some rather beastly ARCTIC S4028-15K fans to ensure there is at least some air flow through the coal and hepa. mostly way to weak fans are used. it is noisy, but effective, you cant have silence and high cfm, you can sadly pick only one.
