【TDS to 0】This deionized water filter can further remove dissolved solids from membrane filtered water and is designed to take RO water to a new level by reducing TDS to 0.

【Advanced DI Filtration】The Frizzlife DI210C DI filter uses ion exchange resins to remove mineral ions, keep water free of hardness, and prevent limescale buildup. This occurs by replacing ions with hydrogen (H+) and hydroxide (OH-) ions, which combine to form water (H2O).

【Universal Fit for Most RO Systems】This mixed-bed resin water filter system can be easily installed with most RO systems with 1/4-inch tubing, providing an additional layer of purity. Thanks to the inline design, all you need to do is attach this DI inline water filter directly to your RO unit with the included clamps.

【Color-Changing Deionization Resin】The lifespan of the DI cartridge varies depending on the water quality in different areas. When the media is depleted, the color changes from blue to light brown.

【Perfect Addition to Your Reverse Osmosis System】 Frizzlife's inline deionization filter improves water quality for drinking, coffee brewing, hydroponic gardening, and maintaining thriving aquariums. It creates a clean and stable aquatic environment that closely mimics a natural ecosystem and supports a thriving, balanced ecosystem for fish and plants alike.
