22 OZ. CAPACITY: Lightweight and durable, it measures just 11.2” tall and 2.6” in diameter so you can take it anywhere. < EFFICIENT FILTRATION: The Sport Berkey Bottle uses the same filtration medium as the larger Black Berkey Purification Elements, which are used in the free-standing gravity-fed systems. With no pumping required, the bottle’s filter reduces microorganisms by greater than 99.9% and reduces viruses by greater than 97%. It also removes or dramatically reduces toxic chemicals, heavy metals, volatile organic compounds, trihalomethanes, detergents, pesticides, herbicides, chlorides, pharmaceuticals.
ECONOMICAL AND LONG-LASTING: The Sport Berkey bottle has a storage life of 50 years and provides about 160 refills when using raw and untreated water, or about 640 refills using municipal tap water.
NON-LEACHING PLASTIC CONSTRUCTION: The Sport Berkey Bottle is made from a non-leaching, LDPE #4 medical grade polymer, which is BPA-free.
INDEPENDENT TESTING: Berkey uses several independent third-party labs to test a broad range of potential contaminants.
This advanced technology was developed, refined, and proven through diligent, investigative research and testing performed by water purification specialists, researchers and engineers. The media within the filter element removes contaminants by a surface phenomenon known as "adsorption" which results from the molecular attraction of substances to the surface of the media. As the bottle is pressed, the source water is forced through the filter. The quality and volume of media used, determine the rate of adsorption. The flow rate or time of exposure through the filter has been calculated to yield the greatest volume removal of toxic chemicals caused by pollution from industry and agriculture. This exclusive filter element is impregnated with proprietary "absorbing" media that promotes IONIC "absorption" of pollutants within the micro-porous element, such as aluminum, cadmium, chromium, copper, lead, mercury, and other dangerous heavy metals. The "Tortuous Path" structure of these pores gives it its unique characteristics.The Sport Berkey® Portable Water Purifier offers a convenient and portable filtration system using medical grade technology. Note: If using a source of water that might contain extreme bacteriological or viral contamination, it is recommended that two drops of plain chlorinated bleach or iodine be added to each refill before filtering. This will kill minute pathogens such as viruses. The disinfectant will then be filtered from the water entirely removing its odor, color and taste.
