This is really great, at last a water filter that does not need tablets, chemicals or anything else, and it’s a straw that actually turns untreated water into good drinking water with no hassle.

These devices are great for people who wish to travel and they cannot be sure of the quality of the water, or even in places where there has been a flood or some other natural disaster. When people travel, around 50% report some sort of sickness.

Features:

Portable – iStraw is Compact, lightweight and simple to use, an essential companion for all travelers.
Clean – Unlike water purification tablets, leaves no aftertaste.
Safe – iStraw is used for help in protection against waterborne bacteria and protozoa that are present in the drinking water of many countries.
Secure – Reduces up to 99.99999% of all waterborne bacteria, including Giardia and Cryptosporidium.
Rechargeable – Reusable – filters up to 500 liters of water.

For just $40 this device could save you much more.
