Product review (3 stars): Can't see a difference
I always thought this would make some difference for my water, but it doesn't.
I have hard water and this thing does absolutely nothing to remove any grains from the pipes.
Whenever I spill any water I have to clean it up right away or else it'll dry up in an unsightly calcium bicarbonate deposit and make stains on my shiny stainless steel fridge. So not really thrilled about it.
The table top filter does a better job at softening the water just enough that my tea pot doesn't get the scales on the inside. But the fridge filter is a waste of money. Not going to purchase anymore.
