The Sport Berkey water bottle is the ultimate in personal water purification systems. Unlike the other Berkey water purification systems
which are gravity-fed, the Sport Berkey provides on-demand purification. In other words, as you suck water from the straw, or simply squeeze the sides of the bottle, water is forced through its miniature Black Berkey Element as it is purified. No need to tilt the bottle at all! The bottle is made from BPA-free plastic and holds 22 ounces of water.
The Sport Berkey's Black Berkey Element is replaceable and has been rated at approximately 640 refills tap-water. The Sport Berkey Replacement Element is affordable, easy-to-replace, and practical. Never waste any more money on bottled water!
If you find yourself using fresh-water from a questionable source of turbid water, such as a lake, murky/stagnant pond, stream with high-sediment, or other source with questionable quality, the Sport Berkey is the perfect solution for your day-pack or long-term equipment.
