Cuckoo / Coway / 3m with hot & cold dispenser

I agree with you at first glance most customer will want to get filter with hot and cold functions because it offers convenient.

You don't need to spend rm2-3k just to get hot & cold functions, just buy thermal dispenser (cost less than rm80) for instant hot water and put ice cubes for cold water. (Free) what we need from a good water filter is that it gives us clean water to drink (no other special effect).

Cuckoo / Coway both give you reverse osmosis water. the downside of RO water is WHO (world health Organization) doesn't not recommend that for Long term drinking purpose.
