All of our filters are produced by American companies with American water quality standards. These trusted brands include: Dow, GE water technologies, MATRIKX, Pentek and Purtrex.

For proper tank maintenance, Bulk Reef Supply recommends changing the filters in your RO/DI System every 6 months. To make re-ordering a breeze, we have created filter kits to match all of our value, standard, chloramines and drinking water systems.
