Some time ago, I published an article on the pH‑value of water produced by reverse‑osmosis membranes. Feel free to revisit it if you have not read the content.

What is the pH of reverse osmosis water？

I mentioned previously that water filtered by an RO system is weakly acidic instead of alkaline.

Today I will expand on this subject and talk about the pH levels of drinking‑water people normally come across.

Tap water is generally slightly alkaline.

Water from reverse‑osmosis filters tends to be weakly acidic.

Soda water available across China belongs to alkaline drinking‑water.

Water with a perfectly‑neutral pH would be the ideal option. In real‑life conditions, however, both mildly‑acidic and slightly‑alkaline drinking‑water suit our daily‑life needs.

That wraps up today’s discussion on this topic. XBYMC aims to build an objective and neutral forum for water‑treatment professionals. You are welcome to share any related questions whenever you like.
