Has anyone seen this yet in commercial applications? It was supposed to be out late last year.

It would be useful to have in your emergency bag.

The FiltersFast website ( article dated 1-5-11 ) said it was to be in production in Feb. I guess they intend to sell it, but I don't see that they sell anything currently.

One problem I've seen repeatedly is that some scientist(s) invent something that looks extremely useful, and thinks it can be made cheaply (these filter bags, est. $0.01 ti 0.05 each), when the realities of production don't match up. When Dr. Paul Oliver came up with the brilliant idea of using black soldier flies for turning food waste and manure into a high-protein animal and fish food, he estimated the unit he designed would cost about $10. The reality bites at $190.00.

The same thing may be happening with the teabag filters. Good idea, but not cheap to produce, and possibly not cost effective for the single use.
