The 22oz. Sport Berkey Portable Water bottle is the ideal choice for a personal traveling companion - featuring Berkey's exclusive IONIC ADSORPTION MICRO FILTRATION TECHNOLOGY.
Material: BPA/BPS Free Low-Density Polyethylene
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 Sport Berkey portable water filter 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 water filtering element removes contaminants by the surface phenomenon known as "adsorption" which results from the molecular attraction of molecules to the surface of the media.
