Product review (2 stars): Supco Water Filter - Salty Taste
We purchased these from amazon thinking they would be same as GE brand.  They are much lighter, not as heavy as the ge brand.  I can't tell if the filtering is better or worse but from the weight, it appears whatever is inside there is less of it in the Supco brand.

But I detect a slight salty taste or some aftertaste that was not there before.  I flush the filter with a couple of pitchers of water but the aftertaste is still there.

Anyone else have this experience?  are these even safe??  starting to wonder.
