Product Details


pH UNDER is a non-electric, all-natural, compact Alkaline Water Ionizer with the same proprietary four cartridge system as our Pure Hydration Next Generation model.

pH UNDER delivers the same high-quality Alkaline Antioxidant Water loaded with minerals and molecular hydrogen but is specifically designed for under counter installation. The smaller footprint (16” H x 14” L x 6” W) allows for easy installation under most kitchen sinks.

pH UNDER comes with instructions and everything needed for easy and trouble-free installation:

  • Faucet (Brushed Nickel or Chrome)
  • Angle-stop connector
  • Tubing
  • Full set of cartridges
  • Stand

Installation is simple. Locate a hole on your sink (a knock-out or soap dispenser) or drill a ½” hole at the desired location for the faucet. Install the faucet in desired location. Install angle stop connector to your cold-water supply valve and connect to pH UNDER with supplied tubing. Connect pH UNDER to drinking water faucet with supplied tubing and you’re done!

You can enjoy 9.0-9.5 rated Alkaline water with 0.02 Micron Ultra-Filtration. The faucet makes it easy to get the most of your Ultra-Filtered water, good for cooking, washing fruits and vegetables and of course drinking.

The Ultra-filtration removes harmful contaminants such as Lead, Arsenic, and viruses from your water. Other ionizers can cost thousands of dollars without any filtration, but our all-natural process brings filtered water straight to your table at fractions of the cost. Better skin, digestive health, muscle recovery and immune boosting is right at your fingertips.
