Geekpure C-R05-MF RO Alkaline Remineralization Cartridge

The sixth spot in our list is taken by the Geekpure C-RO5-MF mineral filter. This a pretty decent alkaline filter that’s built nothing but the work is intended for which is to balance the pH level of the water and add back essential minerals.

The C-RO5-MF is made up of bio-stones, silver-pregnated zeolite stones and coral sands which contain all the original minerals that are necessary to make the water taste better and have good alkalinity level.

The filter adds back calcium, potassium, magnesium, and sodium ions into the pure RO water which helps raise its pH value to a much better level.

As for the installation, this is a 10-inch long filter with a diameter measuring 2 inches, so it’s designed to fit any standard under-sink RO system. It has ¼” NPT inlet/outlet thread and can give you service for up to 6 months.
