They are not totaly necessary, but they are definitely an asset in my humble opinion.
Our dishes come out better from the dishwasher, and the laundry uses less powder and does not need added softeners.
I also like a filter on the drinking tap, as I can't stand the clorine taste of unfiltered water..
However. Many of our friends do not have it, and are more than happy without it, so it comes down to preference in the end.
As for the pipe work, the only ones I worry about clogging up, are the ones pushing my blood around!
