Sprite Shower Filter Technology
Sprite products are NSF Certified to standard #177 for shower filtration. Don't be misled by companies who claim NSF Certified Filtration Media. It's not the same as being certified to Standard 177! For a list of Sprite Certified models.. CLICK HERE
Since chlorination is a long established public health practice necessary for the disinfection of drinking water, consumers are aware of the health benefit drinking filtered water can provide. However, it's surprising for some people to learn that 50% of their daily exposure is in the shower. The other 50% comes from their drinking water. Therefore, filtering shower water is equally as important, as filtering drinking water.
Documented scientific studies conclude that taking long hot showers is a health risk. In the enclosed shower stall, chlorine vaporizes where it is inhaled. To a lesser degree, dermal absorption also occurs. As chlorine is added to kill pathogenic microorganisms, such as bacteria, the highly reactive chlorine combines with fatty acids and carbon fragments to form a variety of toxic compounds. Medical studies suggest a link between absorption and inhalation of chlorine in the shower environment, with elevated risks for diseases and serious illnesses. Showering in chlorinated water may also cause pre-existing conditions, such as asthma and eczema, to become exacerbated.
In addition to health benefits of filtering water, there are cosmetic benefits. Symptoms of chlorine exposure are dry and/or flaking skin, dry brittle hair and red irritated eyes. Filtering the shower water reduces these symptoms. Skin and hair feel softer and eyes become less red and irritated.
SPRITE's filtration technology makes it possible...
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, 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.
Sprite shower filters work 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.
Redox Filtration Medias
Chlorgon is one type of Redox filtration media. Researched, developed and patented by David Farley, CEO of Sprite Industries, Inc., Chlorgon converts free chlorine and some combined chlorines, such as sodium hypochlorite (liquid swimming pool chlorine), to a harmless chloride. Chlorgon also works well in a variety of temperatures from hot to cold. Chlorgon is also the active ingredient for Sprite's Mediterranean Blue: De-chlorinating Bath Salts.
Kinetic Degreadation Fluxion, or KDF, is another type of Redox filtration media. Researched, developed and patented by Don Heskett, founder of KDF fluid treatment, KDF converts free chlorine to a harmless chloride. This media of high-purity copper-zinc formulations is used in pretreatment, primary treatment, and wastewater applications. Patented KDF process media are 100 percent recyclable and contain no chemical additives. Hospitals, restaurants, municipal water treatment facilities, and homes rely on KDF process media to safely reduce or remove free chlorine, iron oxides and hydrogen sulfide.
All Sprite filtered shower products contain both Chlorgon, and KDF filtration medias.
Why Not Carbon?
Carbon is an excellent filtration media when used under the right conditions, such as, in point-of-use drinking filters. However, carbon-drinking filters are designed to filter tap water under conditions that are much different than found with shower water.
The temperature of tap water ranges from 60- 75 degrees (F).
Showering temperatures typically range from 85-105 degrees (F).
Carbon is a cold water filter. It is most effective at temperature ranges of 50-80 degrees (F). At higher temperatures, carbon becomes ineffective. It will "off-load" and release contaminants into the water. Sprite shower filtration media was designed for hot water, becoming more efficient as the water temperature increases.
The flow rate of most drinking water filters is less than 1/2 gallon per minute (GMP).
Shower water flows at a minimum of 2.5 GPM (5x greater).
Even using cold water, a minimum of 5x the amount of carbon would be necessary to filter the shower water.
Most drinking filters produce 1-3 gallons per day (GPD).
Shower usage ranges from 12.5-50 GPD (12x greater).
Even with cold water and a 5x larger carbon filter, the filter would have to be an additional 12x larger, or a total of 60x the size of the original tap water filter.
Of course, you don't shower in cold water and wouldn't use a 60 lb. shower filter. And we wouldn't cut a carbon filter in half and expect it to adequately filter shower water. Instead, Sprite invested a great amount research developing a line of realistic catalytic shower filters that filter both free and combined chlorines, dirt, sediment, odors, hydrogen sulfide, iron oxides, and more, from your shower water.
