Does Hyderabad have hard water?

I have been living in Kondapur for about seven months now, and over the last three months, I’ve noticed salt deposits in my bucket from the minuscule amount of leftover water. Seeing this, I installed a tap water filter (the kind available for around 1K on Amazon). After using it for a month, I went to my native place, and when I returned, the filter had stopped working. At first, I thought the product was faulty, but yesterday, I opened the filter and found it completely clogged with salt-like crystalline deposits and some slimy substance. The buildup had taken over the entire filter. I wanted to know if anyone else has faced this issue. If so, what are you doing to fix it? Hard water is one of the major causes of hair fall and I am quite scared of it.
