The TD-9 alkaline remineralization filter restores the natural minerals in your drinking water. Conventional reverse osmosis filters remove important minerals from the water. The TD-9 filter solves this problem and ensures the healthiest drinking water.

Filtered water from conventional reverse osmosis filters is slightly acidic. TD-9 balances the alkalinity of reverse osmosis water and adjusts the pH to above 7.5. It also reduces unpleasant tastes and odors and refines the aroma. It gives the water a more natural taste than conventional reverse osmosis water filtration systems.

Stage 3 replacement filter for general reverse osmosis systems.

QUICK CHANGE & TOOL-FREE: Changing the filter on the TD-1 takes less than 9 seconds. Simply unscrew the original filter and replace it with the new TD-F2. You can easily replace it yourself at any time, without any additional tools.

100% SATISFACTION: Our 100% money-back guarantee is as clear as our water. Please replace the TD-9 alkaline remineralization filter every 8–12 months. (Please note that the replacement interval depends heavily on the quality of your supply water and your daily water consumption.)
