Amazing and Portable!
We took this on our honeymoon trip where we had an 8 mile hike each way. Due to elevation, we underestimated how much water we would need and ran out! We were able to find a stream, pull this out of the pack and had two full water bottles of clean mountain water in minutes. This works amazing in an emergency and is fast. 10/10 would recommend. We’ve brought this on every trip since and gotten the home filter as well. Got a great pic of my husband filtering the water too lol.

Reliable, convenient, light, and compact
Super product for backcountry expeditions. The 3L size is perfect for any adventure. Follow the product maintenance steps and you will have a long lasting filter. The weight/pack size to water capacity ratio is perfect for 1 or 2 people on the trail. Gravity filters are by far the best experience in water gathering and use. This is my standard.

Replacement parts?
We loved our gravity peak series! But we only got to use it once before our cat chewed the hose. I cannot seem to find a replacement anywhere. Any suggestions?

Broken on first use
I was given this gravity filter new as a gift and had suspicions on the design where the hard plastic at the base meets the soft bag. I even did preventative taping recognizing that this could be a weak spot. Despite this, and packing it gently, it still separated at this seam within 1.5 days of use on its first 3 day trip. Super disappointed.

Great option for filtering water when travelling
I rely on Lifestraw products around home and when I travel because of their effectiveness in filtering out even the smallest bacteria. This filter system is also really compact for packing so it’s a very helpful addition to Lifestraw options. I should also mention that the first one I bought had a terrible chemical smell but I was easily able to return it for a new one that has no odours, as it should be. Thanks to the very helpful customer service team.
