I suppose we were not comparing apple to apple as Amway and 3M uses a different technology altogether and also belongs to a different price point.
There is no need to make all these comparison so complex. First thing first Syabas sucks!!!
Narrow down the requirements:
1. Sediment. All these dirt, sands, mud, rust.
As far as I am concerned, a 5 micron filter is good enough for bath, washing, cooking. Just make sure your house internal piping after the filter is GI pipe/socket.
2. For drinking. All these bacteria, viruses.
There are few things I know solve these problem. The first is UV. Then RO or pure water allow you to drink direct. And if you dont have these just boil the water.
3. For drinking. All these chemicals especially large quantity of cholrine added to our pipe water on purpose.
RO removed almost all of it till insignificant so minute it will not affect your health. But with RO lacks the natural minerals some say. I am not sure if we need minerals from water source, just that occasionally you drink outside, mamak teh tarik, 100 plus gives you lot of minerals, etc.
Then you can overcome this probem with carbon filter. Any activated carbon filter will absorb and do the job. No need to buy expensive carbon block. The so called super good activated carbon they themselves cannot tell you why it is so different and so good. An activated carbon block is an activated carbon block. The best is made of coconut shell. We have plenty and we/malaysia exports it and to USA and reimport it as branded!!!
Knowing what you have you know what you need to do that is!
Conclusion, 2 simple steps:
1. A sediment filter for the whole house
2. A combination or some of UV/RO/Activated carbon filter or Activated carbon filter + boiling for drinking.
Remember when you cook you are boiling the water.
