Question: Does it remove Protazoa?
Document: The Lifesaver Bottle is the best product I have ever used and at this time I believe the only system in this form to do what it does. Other systems rely on Chemical Cocktails you drink or ceramic technology that DOES NOT remove virus and Bacteria! Reading some of the other reviews and saw one person said he was not worried about removing the virus and the bacteria...WHAT?
For you backpackers, I would peg the size of the 6000 between a 1 liter and 2 liter soda bottle. The distributor reports that the activated carbon filter is optional. This could save a good chunk of money in operating costs if you want to forgo the convenience of an integrated filter in favor of trying to fashion your own external ACTIVATED carbon filter at a much greater savings. The activated carbon filter can remove certain organic contaminants an improve taste dramatically.
this is the greatest product and I am very happy with it.it might have some plastic taste at first, but this is normal for anything made from plastic.takes time to get thru the taste and I personally am very happy with the product.I have looked at many different items, this was the best without having to carry so many other products to get clean water.
When you read the specs on this bottle and you understand the level of filtration this system goes to it is astounding! Essentially the inventor has created an industrial process in this compact size, that's amazing!
When combined with small bottle of water (which can also be used for water container for this filter), one can save a lot of weight when going on a long hike. But not so much on short 1 hour hikes.Cons:1)Rather bulky. This bottle is about 70% size of 1 liter coke bottle (large size).2)Water comes out in small streams and its flow can't be controlled.
Water comes out clean as a whistle. I tested this using my garden pond which is full of muck. Lots of moles and mice drown in it so I thought it would be full of disease. Scooped up water into this bottle and filtered it out. Came out clean and refreshing. My only complaint is that the water comes out FAST, too fast for sport use.Also, for size comparison, this bottle is about the size of a one liter soda bottle.Great for traveling to Africa.
Was looking for a complete unit with strap. This was a gift for my son who is in the military overseas.. He received unit with no strap. Instructions stated a strap was enclosed and how to attach it. Seller and distributer should get together to resolve this matter. Did not like paying for the strap.
Treat the pumped bottle like a shaken can of soda. Open it slowly and carefully.
Those complaining about the poor taste of the water - yes it could be improved. However you're kinda missing the point.You could take raw sewage water, pour it into this bottle, and it will create sterile drinking water that is safe for consumption. It is designed to create a water source from something that would taste much worse and likely, kill you. So, perspective folks. It does what it is designed to do, and that is save lives.
This was a Christmas gift for my husband this year.. but we actually had the benefit of seeing it in action at a conference in Va Beach.. it was Great.. every family should own one in the event of any emergency in which the drinking water is unsafe.
