Are alkaline water filters necessary?

[koffeelani3]

The price around RM 2.7k++ can pay installment if u want to, around RM 75++ per month but i bought it cash and self-install. it works well to me.. I dont have to worry if i forgot to boiled a water to fill in my bottles or I run out of water supply... Ready to go!

I see to cheap to me! I will buy 2 or more and will buy it for my parents because they always boiled a water to drink and need to cold it down if the want to fill in the bottles. And i will do more research about panasonic ionizer
