Chlorine is added to water to destroy pathogenic microorganisms such as bacteria. Highly reactive chlorine is compounded with fatty acids and carbon, producing various toxic substances . Medical studies highlight the increased risk of developing illnesses as well as serious diseases associated with absorption and inhalation of chlorine.
Showering in chlorinated water it can also lead to worsening previously developed illnesses such as asthma or eczema.
In addition to the benefits of water filtering, cosmetic benefits have to be mentioned. Symptoms of negative effects of chlorine include dry or peeling skin, dry brittle hair, and red irritated eyes. Filtering water when showering leads to a reduction in these symptoms.
Berkey shower filter works on a similar principle as a catalyst in a car, and uses high-purity, copper and zinc patented calcium sulfide mixtures to filter. In the shower filter, free chlorine is converted to harmless salt.
The technical name for this chemical reaction - "reductive oxidation" - is commonly referred to as redox. The redox reactions may be complex in chemical terms, but essentially in the redox reaction the electrons are transferred between the molecules and other substances are formed. For example, free chlorine comes into contact with the filter medium, turns into a water-free, harmless chlorine. With this reaction, free chlorine turns into larger chlorine molecules that are too large to evaporate or absorb the skin, so the water will safely wash away. Evaporation of such a salt-based molecule requires a higher temperature than conventional water heaters allow, and its size does not allow absorption into the skin . The media used in the Berkey ™ shower filter converts free chlorine and some chloramines into harmless salt. These media, a patented mixture of copper, zinc and calcium sulphide, work well at different temperatures, ranging from cold to hot (up to 49 degrees Celsius).
If possible, do not use the Berkey shower filter with a stop valve.
If a stop valve is necessary, it must be installed in front of the shower filter.
If the shut-off valve was installed behind the filter, there would be an excessive increase in pressure in the filter leading to its damage and subsequent loss of warranty.
