pH after the mineral post-filter

7.5-8.5

Nord’s specification for One Mineral Restore. The exact mineral content and pH depend on your source water and filter age.

Balanced, not aggressive.

Water with almost everything removed is called “aggressive” in water treatment: it readily dissolves what it touches. Adding minerals back gives it balance, and a rounder taste.

Included, not an upgrade.

One Mineral Restore comes with every system. Pull it out and push in a new one about every 90 days. See the cartridge.
