The AQUARIUS TWIN™ Under-the-Sink Water Filter (AQ-120) is a great option for clean, healthy water from the convenience of your kitchen sink. The AQ-120 offers you clean water for drinking, cooking, and cleaning, and includes two proprietary filtration cartridges:

  • Aquaspace® Compound Cartridge will remove a wide range of organic and inorganic compounds including: Lead, Chlorine, Volatile Organic Compounds (VOCs), Herbicides & Pesticides, Industrial Solvents, Pharmaceuticals, as well as bad taste, odor, and color, while also leaving in beneficial dissolved minerals that are essential for good health.
  • Super 4-in-1 Sediment Cartridge is Multi-Sectional 4-in-1 (30-15-5-1 Micron Multi-Sectional Sediment Cartridge).  It has been designed to fit into most standard filter housings. Because the APR-4N1 is multi sectional and uses gradual filtration, it can last longer than a single section cartridge.

This system comes complete with a lead-free faucet in your choice of brushed nickel or chromeThe lever on the faucet can be left in any position for continuous hands off flow for the washing of vegetables or filling those large pots for boiling water.The unit also comes with an installation kit and a wall mounting bracket.

You can also choose to add our AQUATOMIC Hydrating Magnets to your unit for increased hydration. The Magnets are built into the housing of the unit, allowing for all water that passes through the field to be restructured, making the water more bio-available to your body. This means it's easier for your body to absorb the H2O molecules, helping you get the most out of your drinking water. Plus it makes the water softer and wetter!

You can read more about the science behind magnets on our Aquatomic tech page.

Please note: Magnets are only available with white colored housing.

The Aquaspace® Compound has been tested and certified by the National Testing Laboratories for the reduction of organic, industrial, and agricultural pollutants including chlorine, chloroform, herbicides, pesticides, and heavy metals such as lead. In addition, Aquaspace removes unpleasant colors, tastes, odors, sediment and turbidity. It does not remove beneficial dissolved minerals that are essential for good health.

The Super 4-in-1 Sediment Cartridge gradually filters ALL sizes of sediment from big to small, each layer only has to filter its designated size sediment.  It is wider than most sediment cartridges to accommodate FOUR SEPARATE FILTER ZONES of 30,15, 5, and 1 microns for enhanced filtration and longer life than traditional 1 micron rated cartridges.

The AQUATOMIC® will decluster the water increasing its bioavailibility thus hydrating you quicker.
