Hello:

Thinking of getting one of those water filters that attach to the end of the
faucet.
Have heard about the Pure and Brita brands, which I guess are the two big
names for this kind of thing.

But have seen a model by WaterPic that the wife seems to
like better.

Anyone ever use the F-7 WaterPic unit ?

Opinions on ?

How does it compare to the other two brands I mentioned ?

BTW: "typically," how long would the filters for this unit likely last ?

Thanks,
B.
