: Can boiling the water solve the problems?
: Boiling water to kill germs and ensure safety is only applicable at rural areas or areas where no chlorine is added into water.
City water is generally processed by chlorine and the chance of germs growing in the water is so slim that boiling becomes unnecessary. Not only that the mud and the metal content stays in the water, boiling may actually serve the opposite of your intentions.
  
: So boiling chlorine-added water can be harmful?
: According to reports from Osaka Water Authority in Japan, the increase in temperature intensifies the chemical process of carcinogenic materials like trihalomethane. When water reaches 100oC, the trihalomethane content rises 3 times more than normal, i.e. from 15ppm to 55ppm! Even if you turn off the heat right after it comes to boil, the trihalomethane stays in the water and increases the drinker's chance of contracting cancer. Therefore the safest method is still to filter out the chlorine, trihalomethane, mud and metal content before boiling!
  
: Will we lose our natural resistance to germs if we drink only highly purified water?
: This is an interesting question. There are people who want to be healthy, but there are those who worry about being too healthy!! Filters do not take out every content regardless of them being useful or harmful. For example, activated carbon commonly used among filters can effectively take out chlorine and trihalomethane chemicals (in molecules) but not good minerals (in ions) in water.
  
: What is the greenish-blue stain in the sink, bathtub and clothes?
: These stains originate from copper. The chlorine content accelerates oxidation of copper pipes, creating copper chloride, which is green when dried and blue when wet. The pH value of water in Vancouver is between 5.8 and 6.2, eroding the pipes and therefore forming greenish-blue stains. A centralized whole-house filter system can take out the chlorine and balance the pH level in the water and save you the trouble of having those greenish-blue stains.
  
: Is hair loss related to water quality?
: Baldness or hair loss is a very complicated problem, and the reason varies with every individual. However, water is definitely one of the reasons. According to hair specialist Brian Thompson, chlorine is a strong bleaching agent and can damage the protein content in our hair, which becomes brittle and breaks. Using chlorine-added water to wash your hair does make hair fall.
  
: Is chlorine related to dry and itchy skin?
: Yes. Skin is the biggest organ of our body and is highly absorbent and permeable. Chlorine is a chemical element that absorbs water. Its absorbs the water from our skin and makes it dry, crease and itchy. This explains why our skin feels dry after washing our hands and/or face and needs some products (mostly containing chemical content) to moisturize our skin.
