I thought the same so I just have to ask: Can anyone here with the facelift (Edit: Or Model X ofc ) and without the Premium Package confirm that they don't have this big filter?The various bits I've read about the system have talked about activated carbon filter layers to capture acidic and alkaline gasses - I assumed that's what the "secondary filter" was, in which case I'd expect it to be behind the HEPA..
