This high flow RO filter is made and tested in the United States with American-made tubing and fittings. Every component is housed in stainless steel powder-coated brackets made in LA, California. 

Chloramine removal in city water needs a KDF85/CAT carbon filter. It has a high flow pleated sediment filter, which is fully reusable and washable. The GX400 filter has a compact design, and all the components are located strategically for easy maintenance. 

Anti-bacteriostatic properties of GX400 prevent the build-up of microbes in the reverse osmosis filter. It comes with clear pre-filter housing that allows the user to watch out when it gets dirty. We recommend you change your filter when its color turns coconut brown.
