How does Qwench Pure Shower Filter’s 100 % KDF-55 technology work?
To be used in water treatment, chlorine has to be separated from its sodium chlorine bond. This is done through an electro-chemical reaction. This reaction occurs by taking a saturated solution of brine water (water and table salt), placing it in a closed environment with positive and negative electrodes and exposing it to electrical current. This causes the separation of chlorine gas (free chlorine) from sodium, a soft metal. The chlorine gas is then pressurized to form a liquid. It is this liquefied chlorine that is then injected into our water supply to kill pathogenic bacteria. After the harmful bacteria are eliminated, some residual chlorine remains in our home water sources. This is where the Qwench Pure Shower Filter comes in.
The Qwench Pure Shower Filter uses KDF (Kinetic Degradation Fluxion) technology to reverse the formation of chlorine. KDF-55 is a 50/50 alloy of copper and zinc. This alloy, in a granular mesh form, reduces free chlorine in the treated water. The KDF technology reverses the electro chemical process by using the copper/zinc alloy catalyst to break apart the toxic chlorine molecule into safe chloride ions that easily dissolve in the water and are safely washed away without interacting with your body’s cells.
The USA-produced KDF-55 filter medium is the only material that meets NSF rating standards for hot water filtration. And, while other filters may have only a small amount mixed into other filter mediums, at Qwench, we have manufactured a filter using only 100% KDF-55.
How is this different from the Carbon Block Method? I’ve heard that’s cheaper.
Granular Activated Carbon (GAC) is a type of carbon processed to be micro-porous. It is effective in filtering contaminants from both water and air. It does, however, have its limitations.
Carbon works via adsorption, rather than an electro-chemical process. Its small low-volume pores result in a greater surface area on which chlorine can adhere. Adsorption is the adhesion of atoms, ions, or molecules from a gas, liquid, or dissolved solid to a surface. This process creates a film of the adsorbate on the surface of the adsorbent. With the carbon block method, chlorine is adsorbed by the carbon rather than converting it. This leads to a much shorter effective life of the filter as before long, the surface area of your GAC becomes clogged, reducing it filtration abilities.
While the life of your Qwench Pure Shower Filter is measured in thousands of gallons, the life of a GAC filter is measured in mere hundreds of gallons. This means that a GAC filter will reach a point where it will not be able to hold any more chlorine and will begin to offload some of what it has adsorbed right back in to your water source.
Additional disadvantages of GAC systems include:
- GAC is designed for cold water. Hot water exposure can lead to the offloading of the captured contaminants right back into your water.
- GAC is lightweight. In order to keep up with shower flow rates, a GAC filter would need to be 5-10 times larger to keep up with standard water flow.
When can I start benefiting from my new Qwench Pure Shower Filter?
In about five to seven days, the natural balance of your skin and scalp should be restored, contributing to healthier, softer skin and to hair with more shine and body.
