Bacteriostatic Properties 

Designed with rigorous quality controls and introduced after quality lab-testing, this water filter uses KDS (Kinetic Degradation Fluxion) technology for filtering your water.

This filtration method includes a high-quality and purity copper-zinc formulation and uses the Redox process to remove chlorine, lead, mercury, iron, and hydrogen sulfide from water supplies.

The filter can provide 5 long years of filtration without the need for any replacements. This is the thing you need in your refrigerators (including universal refrigerators) for complete water treatment.


20,000 gallons, we repeat 20,000 gallons is the filtration capacity of this water filter and this is something more than anyone can ask for. Imagine buying a very cost-effective inline water filter that will last for 5 whole years with twenty thousand gallons of filtered water.

It is literally maintenance-free if you keep an eye on it and inspect the progress of gallons covered after every six months. Even if you are an amateur in performing your home’s DIY tasks, installing this system will require no special skill or learning.
