Product Description
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.

This seems like a good product, it was shipped quickly...BUT there are absolutely NO instructions for it's use
or any paperwork at all concerning this product. I am disappointed, there should be something to tell you
how to use it, how many uses it's good for, warranty, etc... But nothing,just the product in the box.

I was familiar with the Berkey name as the filter of choice when I lived in the jungle in Hawaii with rainwater catchment (and leptospirosis and giardia risk). So it seemed a good choice for my current situation of regular camping trips and also town errands with chlorinated city water.
The customer service on this item was overwhelmingly positive. It arrived fast and well-packaged. I didn't suffer from the lack of instructions that another reviewer mentioned: there was a printed page with a lot of information. They even included a free replacement filter because the shipping to Alaska (which is set by Amazon) was so very high.
For me, it works great. My only concern is that the bottle is a fairly flexible, squeezable plastic and I hope that it's not the leaching kind.
The lid/stopper doesn't leak water: the straw that you drink through is flexible and tucks away into the lid. For my husband, it comes through too slowly - I like to sip, he likes to gulp. So depending on your drinking pace, you may not like this as well as I do!

About 4 years ago I bought a Berkey Light system which is the large 2.75 gallon capacity filter. It has two filter elements in it and can filter up to 4 gallons per hour. I have municipal water at my residence so the water has a very chlorinated smell and taste. Needless to say I have filtered hundreds of gallons of water through that filter and it still produces the purest, cleanest tasting water. Naturally I was curious as to how well a unit this small would compare. I work at a high school that also has less than tasty water available, even from the drinking fountains. So I mainly keep the sport bottle there, and it has worked great. The Berkey filter element in this bottle does an amazing job. I've only used it once in a natural water source when I was kayaking, and it filtered creek water just as well. I read the info on the level of filtration it provides and feel confident and safe in drinking water that has gone through the Berkey filter. Just make sure you rinse the filter real well once you've used it in a natural source as it may have floating debris caught in the filter, which over time could clog it up. I highly recommend any Berkey product.

Great so far...
I was worried by several of the lower reviews, but after watching a few YouTube video reviews I decided that it was worth the $23 risk. Read more

Water Filter
I am well-pleased with the water filters I purchased. The only thing I wish is, that there were more instructions with it.

Well, I got this bottle after reading the reviews. When mine came in, I filled it with tap water to test it out. I could not get any water flow out of the straw. Read more

very good bottle
Like others say it leaks. Mine leaks when upside down. Other than that it stays dry. It is pretty easy to get what up the straw. Think of drinking a milkshake through a straw. Read more
