This our replacement RO filter set for the REO Pure EC 4 reverse osmosis system. Most reverse osmosis filter sets should be changed once per year. Depending on your water quality, filters generally get dirty and should be replaced in order to keep your membrane working properly, and keep cleaning contaminants out of your drinking water.

A sanitizer kit is also available as well. When you change your filters you should sanitize your systems before replacing them, to help keep the system clear of any harmful bacteria.
