What is Quantum Disinfection™?

Quantum Disinfection™ is a revolutionary, patented technology that uses quantum mechanic principles of electron movement to create surface catalytic sites. This is the first time such a technology has been used to disinfect water.

How does it work?

All matter has electrons and protons, some are charged more than others like magnets pulling or pushing opposites. Reyn uses the power of this energy in the form of highly charged electrons which pulls the positive charges out of the pathogen essentially destroying them.  

What do Reyn filters kill?

All of our products use Quantum Disinfection™ to kill microorganisms including viruses, bacteria, yeast, algae, and protozoa.

Will the Reyn make my water taste better?

Yes. The Under Sink Filter includes granular activated carbon (GAC) made of sustainable coconut shells. Combining GAC with Quantum Disinfection™, the Under Sink Filter not only kills microorganisms, but also filters out VOCs, PFAS, and common contaminants that make your water taste bad. The rest of our products that do not include GAC, still improve taste by killing bad smelling microorganisms, improving pH balance, and reducing chlorine and fluoride.

Is Quantum Disinfection™ a purifier like Reverse Osmosis?

No. Quantum Disinfection™ is more like UV. It's purpose is to disinfect water, rather than filter it.


Why would I need this if my tap water is fine?

Although public water utilites must provide water that meets certain quality,it is not sterile.Once city water is “cleaned up,” it must travel through a maze of pipes to your home.  On this journey, it will pick up pathogens. Reyn, on the other hand, sterilizes your water right in your home before you serve it to your pets, water your plants, or drink it yourself.

How is Reyn different from what I have now?

Reyn solves 3 major problems when it comes to sterilizing water. It requires no electricity, no chemicals, and is safe to use at home.

Is Quantum Disinfection™ better than reverse osmosis?

The purpose of Quantum Disinfection™ is more like UV than reverse osmosis. It is not meant to filter the water, but rather to disinfect the water. Reyn can be used as a supplement to reverse osmosis in your home to ensure safe drinking water.

Can Reyn replace my ultraviolet system?

Yes, we encourage it! UV not only is expensive and energy consuming, it only deactivates pathogens rather than killing them. This process can create volatile matter in your water called dioxin, which is toxic to humans and the environment
