Shower Filter FAQ

Shower Filter FAQ


For many decades using a chlorination process to disinfect drinking water has been a common public health practice. Even though it is widely used, chlorine can have negative effects. The highly reactive chlorine combines with fatty acids and carbon fragments and forms toxic compounds. Medical studies suggest a link between absorption and inhalation of chlorine in the shower environment with elevated risks for diseases and serious illness. About half of the exposure to chlorine happens in the shower. Hot water temperatures changes free-chlorine from the liquid state to the gas state, especially in an enclosed shower stall. When it is in the form of gas it vaporizes and inevitably is inhaled. Chlorine also permeates the skin while in a shower or bath. Pre-existing conditions such as asthma and eczema may flare up when showering in chlorinated water. Symptoms of chlorine exposure are: dry flaking skin, dry brittle hair, and red irritated eyes. Filtering shower water is equally as important as filtering drinking water.

The Shower Filter unit uses a patented blend of high-purity Calcium Sulfide, Copper and Zinc. It works comparatively to a catalytic converter in a vehicle. Both reduce the toxins being emitted through a Redox Reaction. The free chlorine in showers are converted to harmless chloride salt. The media inside the filter changes the free chlorine into a benign water-soluble chloride molecule. This salt-based molecule requires more energy (heat) to evaporate at shower temperatures and is too large to be absorbed into the skin. It simply is carried down the water supply. 

Free Chlorine: Chlorine that has not yet combined with other elements to create chloramines which allows to actively remove contaminants.

Redox Reaction: Reduction Oxidation chemical reaction. Electrons are transferred between molecules, creating new elements.

NOTE: If possible do not use the Shower Filter unit with a shut-off valve. If a shut-off valve is absolutely necessary, please make sure it is installed inline above and before the Shower Filter unit. Use of a shut-off valve after the Shower Filter unit may result in excessive pressure buildup inside the Shower Filter unit causing the filter to be damaged and voiding your warranty.

The maximum operating temperature for the Shower Filter is rated at 120°F. To avoid scalding in the shower, the temperature should not exceed 110°F.

The process of oxidation occurs when the filter is activated by water. It will lose its filtering capability over time. If your shower filter has not been used in a few months, it should be replaced. Testing for the Shower Filter is based on continual usage. 

Filter replacement: All Shower Filters typically last up to 25,000 gallons or one year whichever comes first. Shop replacement filters.

The Shower Filter contains a patented high purity blend of Zinc, Calcium, and Copper which are most effective in reducing free-chlorine, dirt, and odors. Reduces up to 95% of chlorine which reduces chemical absorption and vapor inhalation in the shower environment. Reduces the levels of hydrogen sulfide, iron, and iron oxide. Reduces damage to hair and skin. It also kills bacteria and inhibits the growth of algae, and fungi. The filter kills bacteria 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. Soluble lead cations are reduced to insoluble lead atoms, which are electroplated onto the surface of the filter.

The filter will fit most standard shower arms that have a 0.5" diameter (standard size for the U.S.) With the massaging shower head assembled it is approximately 9" long (8.25"L x 3"D). The replacement filter is 3" in diameter with a length of 5.5".  

The Shower Filter does not remove Chloramine. Chlorine exists in two forms; combined available chlorine, and free available chlorine (free-chlorine). Combined available chlorine is present as chloramine or other derivatives in water. Free available chlorine is the residual chlorine present as dissolved gas, hypochlorous acid, or hypochlorite not combined with ammonia. The Shower Filter removes the free available chlorine which presents the most danger to the human body. 

NOTE: Simple OTO (ortho toluidine) type chlorine tests cannot be relied upon to show the presence of free available chlorine. This type of test also shows the presence of combined chlorine. When testing for free available chlorine, an inexpensive test is the DPD (N,N-diethyl-p-phenylenediamine) method.

The Shower Filter can withstand a maximum pressure of 125 PSI.
