Waterdrop WD-ALK35 Alkaline Mineralization Filter for RO Systems | pH Balance & Mineral Restoration

Upgrade your RO water with the Waterdrop WD-ALK35

Move beyond pure water and invite a fuller, more balanced sip with the WD-ALK35. This alkaline mineralization filter works with your existing reverse osmosis setup to introduce minerals and nudge the water pH toward a comfortable range, all while preserving the clean taste you expect from filtered water. The integrated PCC technology helps achieve a gentle mineral boost, aiming for a pH window around 7.5–9.5. Note that the WD-ALK35 is not compatible with the X series Reverse Osmosis System.

Designed for straightforward integration, the WD-ALK35 fits undersink RO systems or compatible refrigerator filtration paths via a 1/4" quick-connect. This makes installation and routine maintenance feel manageable without altering your current water routine. When you pour a glass or brew a beverage, you may notice a more rounded mineral profile that complements everyday hydration and enhances the character of coffee and tea.
