## Overview

The OKO L-2 Water Bottle Filter utilizes advanced NASA-derived filtration technology, providing a reliable solution for clean drinking water. With a remarkable 100-gallon capacity and a lightweight design, it's perfect for outdoor activities like hiking and camping, ensuring you stay refreshed wherever your adventures take you.

## Description

OKO Level-2 filtration, originally developed through a NASA grant for space stations, is now available for consumer use. Simply put, it is the state-of-the-art in water filtration technology. Our patent-pending Upstream Valve returns any backwashed fluid into the "unfiltered" water area for re-filtration and to ensure that every sip is pure, fresh and clean. In addition to a 2 micron pore size, the material utilizes a positively charged electro-adsorption (attraction and retention) process to draw and trap harmful agents much smaller than its pore size. Charge fields, activated upon water contact extend 1micron each to virtually close the pore to any intruding agents. Using built-in silver ions, the material then kills bacteria upon contact. A stack of over 400 such pores in the 0.8mm thickness of the filter create a "tortuous path" which a harmful agent would have to travel through in order to make it across.

## Customer Reviews

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Basic equipment for tough environments.
  

*by N***O on Reviewed in the United States on June 16, 2013*

Read the manual... enough said. It does the job in many countries and environments. This is NOT a toy... it is a working tool for those in need of a small, effective filter for water gathered from primitive sources. Best gathered from running water or from the earth. Not a filter for insecticide laced runoff from farms.

### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    Lv2 filter is good
  

*by G***N on Reviewed in the United States on March 21, 2014*

I havent used it yet because I still have the original filter in the bottle and since it lasts about 100 gallons, it will be a while before I replace it with this one

### ⭐ 1.0 out of 5 stars







  
  
    What a waste.
  

*by S***E on Reviewed in the United States on May 23, 2013*

The bottle broke before we had a chance to use the extra filters purchased...Now we have two brand new filters...for nothing.
