Answer is all in the thread, need to read

Summary :

ELKEN = RO WATER = PUREST & CLEANEST water (no contaminants and no minerals)

However, most elderly says when water is too clean it is not good also. From online research, RO water pH level is 6 - 6.5 (mild acidic) this is because there is no mineral in the water, hence it is not good for health. There are many debates online, just need to read up and decide what is best for you and your family.

I got what u are trying to say, drinking RO water (no minerals) but we could get back the minerals in our food such as meat or fruits.

There is no 100% answer whether Alkaline or RO water is the best, that is why from the start i did mention "read up online" and choose what u think is the best for your family.

Til today there are still many debates and no 100% answer yet but definitely drinking clean water with good filtration system is the safest rather than drinking gimmick water such as breaking molecules, adding oxygen and etc etc. There are just too much info and it is quite impossible for me to type them all out, you need to read it in GOOGLE, alternatively, you can also drop by my shop and ask me anything you would like to know.

I am currently using Aquaphor DWM 101 (RO filter with remineralization system) as testing before marketing it in Malaysia. If you want the cleanest, this is definitely better than those without remineralization. However, i personally thinks Aquaphor Crystal Eco is good enough.
