This shower filter contains KDF 55 granules, which are most effective in removing or reducing chlorine, hydrogen sulfide, microorganisms, scale and water-soluble heavy metals such as lead, mercury, and iron. KDF process media also kill bacteria and inhibit the growth of bacteria, algae, and fungi. As an added benefit, KDF media reduce lime scale, mold, and fungi in your shower. KDF process media are completely safe so the process is not toxic and does not cause any adverse side effects.
In the shower environment, chlorine can either be in liquid or gas state. At higher water temperatures in the enclosed shower stall, free-chlorine moves from the liquid to the gas state, where it vaporizes and subsequently is inhaled. The United States regulates all showerhead flow at 2.5 gallons per minute. Thus, the science behind shower filtration must take into account the unique situation in the shower, including temperature, flow rate and volume.
Our Dual Media KDF Shower Filter works on a similar principle to a Catalytic Converter in an automobile. In shower filtration free-chlorine is converted into a harmless chloride. The scientific name for this chemical reaction is known as "Reduction-Oxidation", commonly referred to as Redox. Redox reactions can be chemically complex. Simply stated, during a Redox reaction electrons are transferred between molecules, creating new elements. For instance, when free-chlorine comes in contact with the filtration media, it is changed into a benign, water-soluble chloride. This reaction changes free-chlorine to a larger chloride element, too large to evaporate or be absorbed by the skin. It is then carried harmlessly through the water supply. Hospitals, restaurants, municipal water treatment facilities, and homes rely on KDF process media to safely reduce or remove free chlorine, iron, iron oxides, heavy metals, hydrogen sulfide and bacteria from their water.
KDF shower filter process media are high-purity copper-zinc formulations used in treatment applications to reduce heavy metals, hydrogen sulfide, microorganisms, and scale. Water filtered through redox media controls microorganism growth. Treating water reduces bacteria and other microorganisms by electron transport, causing cellular damage. KDF process media also kill bacteria by direct electrochemical contact and by the flash formation hydroxyl radicals and hydrogen peroxide, both of which interfere with a microorganism's ability to function. High-purity copper-zinc redox media consistently remove 99% of free chlorine by electrochemically reducing dissolved chlorine gas to water-soluble chloride ions.
Redox media remove up to 98% of water-soluble cations (positively-charged ions) of lead, mercury, copper, nickel, chromium, and other dissolved metals. When filtered through KDF media, soluble lead cations are reduced to insoluble lead atoms, which are electroplated onto the surface of the media. All forms of KDF shower filter media are guaranteed for product purity, and a certified analytical sheet accompanies each manufacturing run. KDF media also meet EPA and Food and Drug Administration standards for maximum limits of zinc and copper in potable water.
Each dual media KDF shower filter will typically last 10,000 gallons or one year whichever comes first.

We live in San Diego, (water isn't that great here) & my dad bought me the Berkey Light (drinking water) for my birthday ... I also received the Berkey shower filter. I had no idea a shower could make my skin so smooth. I can't say enough about how smooth my skin feels and how totally rinsed I am with this filter. My daughter has long blond hair (to her waist) and has always had to use conditioner (& a brush in the shower) or her hair would take hours to untangle. Not true with the Berkey shower filter ... there is no build up of 'stuff' on her hair and she has the most beautiful skin now. No clogged pores or blackheads at all. This filter is amazing! The is no better filter than the Berkey - for showers or drinking. My husband thought I was crazy for wanting this for my birthday but he actually told me after less than a week of using both the drinking water and the shower head that he was totally wrong and it is the best water he has ever tasted or showered in. My dad is buying him a shower head for his birthday now - since no one wants to shower in the bathroom without the Berkey shower head. Oh - and my shower walls/knobs stay clean - no water, calcium or lime spots. I LOVE IT!!! You will too!

I have the Berkley shower filter in my home and LOVE it. I do notice way less crud and crust to clean in the tub. I also really prefer to get out of the shower and not smell like I had been in a swimming pool. I am going to buy their drinking water filter as well.

do you think it'd be safe to drink this water too? just wondering what the difference is between the filters..

I love my Berkey Light for drinking and cooking-the insides of my stainless steel pots and even teapot are no longer tan stained. The water from it was used to spritz my hair one day which resulted in much less tangles, softer easier to handle, non-breaking hair so I decided to buy a shower filter also. BERKEY is something everyone should try to gain your healthy body inside and out.

I just bought two, stay tuned...
