Product review (1 stars): STOP!!! Do not add to cart!!
Either amazon or the seller, KillDirt has this product and description wrong. They do not ship the outer filter, only the inner filter. Of course you'll be paying for the outer filter, just not receiving it. The seller is totally unhelpful. I've had very few problems with amazon so I hope they discintinue their relationship with this seller before their reputation suffers.

Very disappointed in this seller.
