"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
"Great bottle for backpacking"
Perfect for international travel
"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!"
Fresh Water!!!!
"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.
"Very compact and durable."
Haven’t really used it since
"Haven’t really used it since it was purchased for our emergency kit."
I use these when I travel.
"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."
Never leave home without it.
"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."
Filter pitcher and collapsible squeeze "bottle"
"the pitcher is a wonderful product.... have purchased them for my Illinois and Wisconsin homes. Have also leaned on my (adult) children to do the same for themselves. As well as for my health conscious Office Manager. I also purchased for my youngest son your 1L Peak Series Collapsible Squeeze: in 2 weeks he'll be backpacking in Yosemite, and it's the perfect solution to quickly being able to fill his personal Nagene bottle, and filtering water for cooking meals for 4; Sorry it took me as long as it did to find you."
Q&A
- Can the carbon filter be used with the LifeStraw Peak Series Gravity Purifier?
- Hi, Yes, the Peak Series Carbon replacement filter can be used with the Gravity Purifier. Set up the purifier as instructed, then attach the carbon filter to the end of the purifier. Hope that helps!
- How many litres does the carbon filter work for?
- Hi, Thanks for the question! The Activated Carbon Filter lasts 100 liters (26 gallons).
- is the carbon filter an threaded "add on" to the membrane filter? I can't tell from the website if the Peak series "carbon" filter is a stand alone, or just an accessory addon to the membrane filter
- Thank you for this question. The carbon filter attachment threads on to the membrane microfilter or the cap of the Peak Series Collapsible and gravity filters. We would recommend this as an add-on to the membrane microfilter to get protection from both pathogens and a reduction in chemicals and heavy metals.
- Can I purchase only the microfilter without the housing? Is for a project
- The filter membrane itself is not sold separately. They are manufactured to ensure safety and are glued into place within the housing.
- How often should I replace the filter? Long story short, I use this everyday for both hikes and going to work.
- Thank you for the question! The Peak Membrane Microfilter can last up to 2,000 liters / 500 gallons when properly cared for and stored when not in use. Depending how often you use it, this may be a couple of years of use. Over time, you will find the filtration rate will slow and eventually water will no longer pass through the filter. It is at this point you will need to replace. The filter is effective as long as water can pass through the filter.
- Why not having a smaller pore size filter? Some others have 0.01micron which can filter virus. Will you have a better filter?
- Hi Daniel! The Peak does not remove viruses but we do sell products that do. The Peak Series is designed for ultimate performance in the backcountry; based on this use-case, we prioritized higher flow rate meant for backcountry and outdoor adventures. If you're looking for a water purifier to use for virus removal, check out our products with a membrane ultrafilter including LifeStraw Mission, Family, Max and Community. You can also email us at info@lifestraw.com for more questions.
