All BulkReefSupply.com Reverse Osmosis units exclusively feature American made DOW, MATRIKX and Purtrex filters. We also use American made MUR-LOK dual EPDM O-ring fittings whenever possible on all of our reverse osmosis units. These NSF certified fittings and filters cost us more than inexpensive imports, but set our units apart from the competition.
