Water filter: where to get?

[wolfie]

I'm looking for a Brita (or similar) device that replaces the standard 5 gallon bottle on a water cooler. When I called Brita (I recall seeing such a device years ago), they said that they had discontinued it, but that I should search for "Brita Water Cooler". When I did, I found actual water coolers that used Brita filters, rather than a bottle replacement for an existing cooler.

Has anyone seen such a device, and if so, where is it sold? Thanks.
