Mineral Stone Replacement Cartridge

4th Phase Water™
Availability: Many in stock
$39.97

This is our mineral stone replacement cartridge that sits at the very bottom of the 4th Phase Gravity Filter System. It cannot be cleaned, and should replaced after 3 - 5  years, depending on how heavy you use the unit.

  • Top tank holds 1.5-gallons

For use in conjunction with 4th Phase Liquid Crystal Concentrate, you should process your water first in a separate and open container for the specified and desired timeframe. Then, pour the full contents in the top chamber of the 4th Phase Countertop Unit, and allow gravity to do the work. The bottom container will now have crystal clear water that greats amazingly well. You can use this water for anything!
