The quality of the treated water supplied by the local authorities may not be meeting drinking water standards. With addition of chlorine and other harsh chemicals raw water is treated in clarifiers and supplied for domestic use. There are many disadvantages associated with this treated water. Most of the time chlorine and other water treatment chemicals are present in low concentration and make adverse effect on our health, on the cloths washed with this water as well as on dishes and other utensils. To get relief from all these things you can install a whole house filter.
By installing a whole house water filter, you can have the luxury of using chlorine free water for bath, cloth wash and dish wash. If you use water having chlorine and other chemical content for dish washing, there is chance of deposition of thin layer of scum on your dishes. And in case the dishes are made of metal, shining of the metal dish will diminish with chemical reaction. If your dishes are of high quality and costly then the importance of using a filter for washing will be more important.
