1. Frizzlife Reverse Osmosis Water Filtration System

The Frizz Life Reverse Osmosis Water Filtration System easily fits into your kitchen faucet and removes up to 99.99% of water contaminants, including fluoride, chlorine, limescale, chloramine, TDS, lead, and other heavy metals.

The most extraordinary feature of the RO filtration system is its alkaline and re-mineralization function. This advanced technique neutralizes water to make it alkaline and the re-mineralization procedure restores healthy minerals, such as calcium.

The filter can also be connected to a refrigerator by using an IMC-1 ice maker connection kit. The device is equipped with a monitor that sends real-time signals to check the system status. It indicates when to replace the filter cartridges and other critical issues. Is that genius, or what?
