Ultimate Alkaline RO-PH90 6-Stage RO Compatible Replacement Filters

We do not sell this RO system, but we DO provide customers with the compatible replacement filters needed to keep this six-stage RO system in top shape! Note that this system has three filter housings hanging down and three chambers laying horizontally across the top. This system specifically has a special, PH-raising cartridge mounted on top that corrects the slight PH change in reverse osmosis water.

Helpful Filter Information

Not all filters have the same replacement schedule. Replace the RO membrane filter every two years. Replace all other filters every 6-12 months. Help keep your system sanitary by never using filters longer than 12 months, except the RO membrane filter, regardless of how much water you use.
