I've been using Lipton for this purpose and don't like all the packaging either. What do you use to contain the dust while you brew overnight? I make mine in a pitcher that lasts a few days.
I use a travel mug with a strainer cup that fits snugly inside. In the morning I pour it out without removing the strainer, so whatever dust fell through and collected in the bottom ends up getting filtered out when it goes back through the wet bits of leaf.
