*Replacement Filter for BMB 10" Heavy Metal & Carbon Filtration (KDF + GAC) Inline Undersink Drinking Water Filter*
The first stage of the filter is KDF (Kinetic Degradation Fluxion), which is an NSF certified high-purity copper and zinc media that filters contaminants in water using an oxidation/reduction (redox) process. The redox process is realised when the copper-zinc media creates an electro-chemical reaction with contaminants.
During this reaction, electrons are transferred between molecules, and new harmless elements are created. For instance free chlorine changed into benign, water-soluble chloride. Similarly, some heavy metals such as copper, lead, mercury and others, react to plate out onto the media’s surface, thus being effectively removed from the incoming water supply.
The KDF process kills bacteria, algae and fungi by direct electrochemical contact and by the flash formation of hydroxyl radicals and hydrogen peroxide, both of which interfere with a microorganism's ability to function.
Some of the major contaminants that KDF removes are: chlorine, hydrogen sulfide, calcium carbonate, magnesium, heavy metals (iron, lead, mercury, chromium, etc.) and microorganisms (bacteria, algae, fungi, etc.).
The second stage of the filter is NSF Certified nano silver impregnated Coconut Shell Granule Activated Carbon (GAC). This two function media not only filters common contaminants found in drinking water but also kills bacteria and reduces taste and odor.
Coconut shell has one of the highest absorption rates in water filtration due to its ultra-high surface area and honeycomb style pores. In fact, just a single 3mm x 3mm granule of BMB Technology coconut shell carbon has an approximate surface area of 6400 m2. Certain chemicals such as chlorine get trapped in these pores and are ultimately removed from water at a very high adsorption rate.
To increase the adsorption process even further, the granules are treated with Nitrogen to make them “activated”. This will not only attract the chemicals into the pores but also make sure they stay there.
Additionally, each granule is impregnated with silver and unlike standard GAC carbon which can promote bacteria growth, the silver will not only prevent the growth of bacteria but also aid in killing them.
Some of the major contaminants that nano silver impregnated Coconut Shell GAC removes are: bacteria, chlorine, chloramine, pesticides, herbicides, nitrate, phosphate, lithium, pharmaceuticals, microplastics, arsenic, asbestos lead, zinc, copper, mercury and other heavy metals.
You may return most new, unopened items within 30 days of delivery for a full refund. We'll also pay the return shipping costs if the return is a result of our error (you received an incorrect or defective item, etc.).
You should expect to receive your refund within four weeks of giving your package to the return shipper, however, in many cases you will receive a refund more quickly. This time period includes the transit time for us to receive your return from the shipper (5 to 10 business days), the time it takes us to process your return once we receive it (3 to 5 business days), and the time it takes your bank to process our refund request (5 to 10 business days).
