On top of the filter, the blue bypass setting can be turned to 0/1/2/3, which one should I set to? Thanks in advance.

I think it depends on the water hardness in your area.

About to buy the Blue but confused about the different filters....which do most go for?

Note the size as they come in S, M, L I once ordered Large and in was too Long to fit under the counter in my instalation. Carbon filter is universal, I like also the magnez filter for taste of water. Over the years I buy one or the other. You can not go wrong with Grohe Blue!!!

I just replaced the new filter, but the water was black at first and then became milky. After 5 mins, the water became transparent. Is this normal?
