actually we dont need any water filter system. Water with bacteria can increase our immune system. Do u know, ppl in the 3rd world like india, they drink directly from water paip normally. Nothing happened to them. Some hav lived over 70 or 80 with that water. But for us, if we go there drink their water, even being boiled twice n filtered, u sure will get sick. Drink the water in hotel there also get sick. if u strong enough, go hospital. if u not strong enough, sure got chance to c gandhi~~
