If you have a lot of calcium in your water, that will plug up filters very quickly. I used to sell laboratory equipment which required and sometimes included internal water filtration. I always recommended frequent filter changes (once a month in some cases) at first to determine to proper intervals for changing filters.

Do look for them on-line.
We have one in our fridge, still expensive, but cheaper on-line.

Note too though I have a whole house filter system, so a lot of the crude never makes it to the frig filter.
