The Berkey manufacturer has filed a lawsuit against the EPA seeking to stop it's unjustified persecution of Berkey Water Filters based on the EPA’s decision this year to treat Berkey Water Filters as though they are pesticides, rather than water filters. The EPA has already ordered the closure of Berkey's largest warehouse. Please see our blog post for the details.

The Sport Berkey 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 remove and/or dramatically reduce a vast array of health-threatening contaminants from questionable sources of water, including remote lakes and streams, stagnant ponds and water supplies in foreign countries where regulations may be sub-standard at best.

The Sport Berkey is ready to use in minutes.

The Sport Berkey is also easy to operate, clean, and maintain.

The Sport Berkey Water FIlter Utilizes: Ionic Adsorption Micro Filtration

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 Water Filter 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.

The Sport Berkey Water Filter eliminates or reduces up to 99.9% of the following contaminants and impurities:

  • Unpleasant taste and odors, cloudiness, silt, sediment and chlorine.
  • Toxic chemicals: Trihalomethanes, VOCs, detergents, pesticides, etc.
  • Harmful microscopic pathogens: Cryptosporidium, Giardia, E-coli >99.99999% and other pathogenic bacteria.
  • Heavy metals: Aluminum, Cadmium, Chromium, Copper, Lead, and Mercury.
  • Radiologicals: Radon 222

Getting Started with the Sport Berkey

Fill the Sport Berkey Water Filter with water, screw on the cap and tighten securely to eliminate leaks. Flush water through the filter by pulling down the lever, so that the straw is exposed, and squeeze water through the filter and out the straw. Repeat this flushing process twice before drinking. This removes excess process dust from the filter. After 2 flushes, rinse the bottle and cap. Your filter bottle is now ready for use.

In the rare cases that the above does not get the Sport Berkey working please try the following.

  1. Remove the filter from the straw on the inside of the bottle. Now lift the cap, straighten the pinch in the straw and stick the straw end in some water to see if the cap is working correctly. If water is able to flow then that top part of the Sport Berkey is working.
  2. Then stick the straw back on the filter and now remove the straw from the inside of the cap. Stick the filter in the cup of water and drink from the straw. If you still have a problem please contact us or your dealer.

Maintenance and Storage

The Sport Berkey Water Filter has a shelf life of 50 years. When the filter system will not be used for an extended period, flush the unit with a chlorinated solution of 1.25 ml. per 2 liters of water. Allow to dry thoroughly with cap removed. Re-assemble and stow. Do not allow filter to freeze, do not place in a microwave oven and do not run hot water through the filter.

Refill Capacity

Water from any source: Up to 160 refills Municipal Water/ Tap Water: Up to 640 refills

Sport Berkey Plastics Composition

The Sport Berkey is made of BPA-free plastics. The bottle is made of LDPE (low density polyethylene) plastic, the bottle cap is made of HDPE (high density polyethylene) and the straw is made of PP (polypropylene) plastic. All of these plastics are not known to leach any chemicals causing cancer or hormone disruption.
