The  Sport Berkey®  Portable Water Filter is the ideal personal protection traveling companion- featuring the IONIC ADSORPTION MICRO FILTRATION SYSTEM. The theory behind this innovation is simple. The bottle’s filter is designed to extract, remove and/or dramatically reduce a vast array of health-threatening contaminants from freshwater sources and water supplies, including those in foreign countries where regulations are often sub-standard.

The  Sport Berkey®  Portable Water Filter removes or reduces up to 99.9% of the following:

• Toxic chemicals (Chlorine, Glyphosate, Hexachlorobenzene, etc)
• Trihalomethanes (Bromoform, Chloroform, etc).
• Volatile Organic Compounds (Benzene, Chloroform, Fluorene, etc).
• Pharmaceuticals (BPA, Ibuprofen, Naproxen, etc).
• Pesticides & Herbicides (Atrazine, PCB’s, Simazine, etc).
• Petroleum Products (diesel, gas, oil, etc).
• Heavy metals (copper, lead, mercury, etc).
• Unpleasant taste and odors, cloudiness, silt, sediment, chlorine and more.

Note: All contaminants that this filter has the ability to remove or reduce may not necessarily be in the user’s water supply.

Ionic Adsorption Micro Filtration System

This advanced technology was developed, refined, and proven through diligent, investigative research and testing performed by water filtration specialists, researchers and engineers. The media within the filter element removes contaminants by a surface phenomenon known as “adsorption”, which results from a molecular attraction of substances to the surfaces 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 contains a 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 the filter its unique characteristics. The  Sport Berkey® Portable Water Filter offers a convenient and portable filtration system using medical-grade technology.

Care and Use

Fill the Sport Berkey® Portable Water Filter with water, screw on the cap, and tighten securely to eliminate leaks. Flush water through Filter by pulling down lever, so that straw is exposed, and squeeze water through Filter and out of the straw. Repeat this flushing process twice before drinking. This removes excess process dust from the Filter. After two flushes, rinse the bottle and cap. Your Filter bottle is now ready for use. Enjoy!

Maintenance and Storage

The  Sport Berkey® Portable Water Filter has a shelf life of 50 years. When the filter system will not be used for an extended period, remove filter and flush the unit with either a chlorinated solution of 1/4 tsp. per one half gallon of water, or a 50/50 mix of 3% Hydrogen Peroxide. Rinse. Allow parts to dry thoroughly with cap removed. Re-assemble and seal in an air tight container if possible. Do not allow filter to freeze, do not place in microwave oven and do not run hot water through the filter.


The  Sport Berkey® Portable Water Bottle has a storage shelf life of 50 years. We recommend replacing the filter after 640 refills of municipal water. Filter may require replacement sooner based upon the quality of influent water.
