When I hear the company say that they shipped "19,600 cartons of 10 filters each" I take that to mean that they have shipped in 19,600 packages of the RE/AL starter kits. Each package of RE/AL includes 10 filters each, hence why they said "of 10 filters each." I am sure they shipped half with Virginian blend and half with American blend filters.
I assume that they already have enough filters in stock, for the reason that you can still purchase them on their website. The starter kits is what is missing, and that is what the 19,600 means. Just my opinion - this seems to make more sense than saying they shipped in 19,600 filters in with no starter kits available.
"Its annoying how unclear they are about this, but still think they meant individual filter packs, because they say, "19,600 cartons of 10 filters each"."
