I bought it from Quadratec, something around $55 plus shipping/taxes . Never heard of inverted air filter. Frankly speaking, all these air filter replacements are more self-satisfaction thing. I suppose the OEM filter works great, and buying a reusable filter could just save some money on replacing it through some years (which sounds ridiculous compared to what we spend on all other upgrades) and, I guess, what is more important for most of us here - just to have another “NOT OEM part“ in your Jeep. That’s it, unless you go with a serious intake system tuning which is no go for me personally as long as the vehicle is under warranty.
Here's what I had to pay for this filter, living in Europe EVERYTHING is really very very expensive
