The Exstream advantage is two-fold. For starters, Exstream is a purification system, not just a filter. It's a little complicated, but the bottom line is this: no filter in the world is small enough to remove viruses, such as Poliovirus type 1 and Rotavirus Strain SA-11. They are a fraction of size of even the smallest bacteria and they are responible for some of the worst diseases. Secondly there are no pumps or hoses which makes Exstream purification systems a convenient alternative to pump-style purifiers. No stopping, unpacking, sorting hoses, pumping or carrying large volumes of water - just dip and sip. |
