Many people think that unsafe water will be drinkable after filtering. This is wrong and can be dangerous. Filters are necessary to trap sediments and particles but they cannot stop or destroy the micro-organisms such as bacteria and viruses. In fact, using only filters can even be dangerous; micro-organisms can reproduce inside the filters making the water more dangerous to drink. Micro-organisms can only be destroyed by chemicals, ozone or ultra-violet rays. Chemicals give a bad test to water and do not necessarily destroy all viruses (not to forget secondary effects). Ozone dosage is difficult to ascertain and can be dangerous at high level. UV is the best option. Laboratory tests have proven that micro-organisms irradiated by UV cannot reproduce anymore since their DNA has been modified The advantage of UV in purification is that a very short exposure by micro-organisms is enough to destroy them (few millisecond) but over exposure has no damaging effects (except for the micro-organisms) on the water and doesn't change the taste and qualities of water.
