That is informative.
Looks like a lot of disassembly to put an extra filter in. I hope the PUP adds an easier route to filter replacement for service engineers.
Without the PUP is it possible to activate the positive pressure setting of ‘bioweapon defense mode’? Or in adding a HEPA filter with this mod are you only adding extra filtration?
Great to hear that though these filters might be an unusual size that they are likely off-the -shelf items.
I could be wrong, but I think all that activating BioWeapon defense mode in my PuP car does is turn the fan up higher.... which presumably creates the positive pressure.
