We would not want to be without our Brita filters.  We have had several models over many years and also had the filter in the last three of our fridge-freezers, including our latest new one.  We find there is a definite improvement to the taste of the water
compared to direct tap water and our kettle never has any accumulation of limescale and so extending its life.
It is so easy to run the water through the filter for the usual tea and coffee and we also filter all water for cooking.  
Refrigerated, filtered water is great for overnight bedside table.
We alway like to take filtered water in our car for making tea, coffee etc., on our camping stove, for picnics.   No need to pay out to buy overpriced water from the shops.
