The Berkey Sport Portable Water bottle is the ideal choice for a personal traveling companion - featuring Sport Berkey's exclusive  IONIC ADSORPTION MICRO FILTRATION SYSTEM. The theory behind this innovation is simple. The Sport bottle's filter is designed to reduce or remove many harmful contaminants from questionable sources of water, including remote streams, lakes, stagnant ponds and sub-standard water supplies in foreign countries where regulations are non-existent or not enforced. 

This superior technology used in the Berkey Sport portable water purifier was developed, refined, and improved through investigative laboratory testing and field research. Our team of water filter experts, field engineers and research specialists have developed this purification process over countless hours of testing and research. The media contained in the Sport Berkey water filter element removes contaminants by the surface phenomenon known as "adsorption" which results from the molecular attraction of molecules to the surface of the media.

As the Berkey Sport bottle is squeezed, the water is forced through the filter. The density and quality of media used, determine the rate of adsorption. The time of exposure through the filter has been carefully calculated to yield the greatest volume removal of toxic chemicals and pollution caused by industry and agriculture. The exclusive filter element of this Sport Bottle is composed of our exclusive proprietary "absorbing" media that promotes IONIC "absorption" of pollutants, such as cadmium, chromium, copper, lead, aluminum, mercury, and other dangerous heavy metals.

The "Tortuous Path" structure of the Sport Berkey's filter element gives it its unique characteristics. The Sport Berkey is a portable Water Purifier and offers a convenient and portable filtration system using medical grade technology.
