  • NL7 Bluefilters water filtration system performs the dual function of cleaning water and remineralizing it to add back any nutritious element that may have been washed off during the removal of impurities.

  • Uses existing household pressure to operate.

  • 7-stage system; 5 filtration stages and 2 re-mineralizing stages to replace essential minerals.

  • Removes impurities such as sand, rust, fluvial silt, pollen, microorganisms, bacteria, and pesticides.

  • Removes chlorine, lead, toxic heavy metals and dissolved gas impurities.

  • The clean water is then remineralized in the sixth stage of RO, providing good tasting water to the storage tank, faucet, and eventually your glasses.

  • Activates metabolism and increases solubility of oxygen.

  • Improves the taste and smell of water.

  • Enjoy the benefit of clean water for washing your fruits and vegetables and for your cooking use.

  • Beneficial for babies as it provides pure mineralized water that can be added to baby formula and food.

  • Easy to install and the system fits conveniently under the sink.

  • Quick change filter cartridges make replacement quick and easy.

  • BPA-Free.

  • Safe for drinking water and safe for health.
