"Love it"
"I bought these things in case the end of the world comes before the end of me. I think they are very expensive, yet I see no alternative. And that makes me sad. I would buy a bigger system from you, but I am on a fixed income. I see where my purchase gives a poor child in a foreign country a year of clean water and I wonder. . . . . . do you have a program like that for our own children here in the US? For kids in Appalachia, on the Reservations, in dilapidated city buildings with rusty pipes? I hope I never have to use these filters, but I now have them, just in case. Thank you for listening. . . . . ."
"Great bottle for backpacking"
"We are using these on a cruise to the Bahamas and then to Italy. We have not used them yet but have used other products. We expect them to work beautifully!"
"We use our Lifestraw to filter our spring water. It was a life saver when we went through Helene in the NC mountains where we live. I recommend the 8 Liter which is the one we use."
"Very compact and durable."
"Haven’t really used it since it was purchased for our emergency kit."
"I can only use filtered or boiled water. When I travel having a cup of tea is easy with the Peak filter. I can squeeze water thru the filter for tea or pour-over coffee and I am a happy traveler."
"This worked amazingly well. We hiked the Grand Canyon and used this in the Colorado River to refill our water. We also had the carbon filter attached and the water tasted great."
