Hi gkbt, First and fore most, I appreciate your input and sincerity in the reply. However, I would like to point out that the value stipulated "high $2k approx." is in fact inaccurate. It is not that expensive. Next, I would first make it known that I am an environmental engineering student currently studying in the university. I have studied all applicable water treatment systems in the world and have a substantial knowledge of the technologies used and the reasons why. I agree that the water quality in Singapore is definitely potable and will not cause any significant harm in the near future. However, if we take a look at the presence of chlorine in the water, it may at the short term show no considerable effects to our health. But in the long run, when something does happen, we fail to point out that chlorine in the water could have had a part to play. Plus, if we fail to remove chlorine away from our system, and we heat up the water there is always that potential chance to form trihalomethanes(THM). Trihalomethanes have been known to be a cause of cancer. Also, I agree with the importance of the micron size of the filter. However, if we are looking at a small micron size, we could unintentionally remove the valuable minerals in the water (such as calcium) that out natural body system requires. This in other words will be forming water close to "ultra-pure water" which is the term given to what we know as NEWater. NEWater is too clean for consumption, hence it is sent to the reservoir to be mixed with minerals before being treated again for our use. Just some input haha:)
