There could be a host of reasons for why your fish died, but I doubt that lead
poisoning was one of them.  I suspect the primary reason was pH shock.  You
should take a sample of your tab water and a sample of the Britta water to
your local fish store and have them run some tests.  

I have used the Britta filter for a few years (for drinking, not for my
fish tank).  They used to pack the replacement filter cartridges in a dry,
sealed plastic bag, and the first few weeks of using a new filter
cartridge, the water tasted sour.  I tested the water and it was quite soft
and acidic (I can't remember exactly what the pH was, but quite acidic).
Recently I have noticed that the new filter cartridges I bought were packed
wet (there is water in the sealed bag), and the sour taste has decreased,
but I haven't retested the water.  I still don't think it's suitable for
aquarium use though.
