## Description

It's time to stop carrying around a bag of plastic parts and multiple water bottles. LifeStraw’s Peak compact squeeze filtration is an all-in-one water storage and filtration device. Made from premium materials, it’s durable enough to last you on your long-haul adventures without having to worry about rips, tears, and punctures. Ultralight and collapsible at less than 4 ounces, you can grab and go, using as a straw filter, storage solution, squeeze system or connecting to other Peak Series systems to best fit your adventure. The filter membrane density has been optimized for flow rate and the over-cap features and smart seal mouthpiece prevent leakage. The robust carrying feature makes it easy to connect to your pack with a carabiner or rope. Your purchase has impact: For every LifeStraw product purchased, a school child in need receives safe water for an entire school year.

Review: Works wonderfully & travels well - I highly recommend this! I purchased it for an overseas mission trip to Africa. It folds up & packs well for travel. I used it in very rural villages where bagged water was all that was available. Before my trip I was cautioned against drinking bagged water, so I bought this in preparation. It comes with instructions for usage & long term storage. It also comes with a syringe for backwashing the filter in case it gets clogged & sluggish. I currently have mine with a salt solution for long term storage. It helps the filter not dry out & it’s explained in the included instructions how to do this. It’s foldable, but the material is very sturdy. When I had it full & was drinking, I squeezed it fairly hard & threw it in my backpack many times. It remained sound. I also love that each purchase provides clean drinking water to very deserving people. I witnessed true poverty during this trip to a 3rd world country, & everyone deserves clean drinking water.
Review: Awesome! - I’ve never used anything like this before and I loved it! Purchased the 1L size for my June/July trip to Peru. Let me tell you that the water in Cusco had a strong smell and it ran milky white out of the tap. This filtration system removed all of that! I brushed my teeth, rinsed out refillable water bottles and cups, and washed/rinsed my invisible aligners with this. During long tours I carried it with water and there was no spillage. I loved that I could just squeeze it directly into what I needed (cup, aligners, bottles, my hands). Without squeezing there’s a nice steady flow of water that runs out of the filter which is nice. Initially the water will have like a charcoal taste, but it goes away after a couple of uses. Make sure you backwash the filter and rinse out the bag. It comes with the backwash syringe and it’s easy to use. Hint for removing the filter without it dropping: The top part of the bag is a stiff plastic, hold onto that when removing/twisting the cap for removal. DO NOT hold onto filter inside the bag while you twist off the cap for removal.

## Features

- Protects against 99.999999% of bacteria (including E.coli, Salmonella), 99.999% of parasites (including Giardia and Cryptosporidium), 99.999% of microplastics, silt, sand, and cloudiness
- Enhanced microfilter performance: Our re-engineered membrane and custom backwash accessory means better performance against sand and silt, maintaining great flow over the long haul
- Ultra-compact, our reconfigured filter is tiny but mighty with a super packable kit that doesn’t sacrifice weight or space
- Extreme durability: 2x thicker, premium materials make it tougher and ultra leak-proof
- Highly versatile means the collapsible squeeze bottle system is designed with every occasion in mind; Use as a bottle, push water through it into cooking containers or other drinkware, use as a straw, or connect to other Peak Series systems

## Questions & Answers

**Q: does this not filter out heavy metals?**
A: No "filter" does. Only water "purifiers" do that. LifesStraw's bag system (about $55) is a purifier though.

**Q: What type of plastic is the bottle made of?**
A: The thick plastic of the bottle itself is soft, allowing one to squeeze the bottle in order to take a drink.  The cap is made of harder plastic.

**Q: how many gallons of water total can one micro filter element in this unit filter,  Are replacement micro filters available?**
A: I did not know the answer to either question, so I referred to Google.  Depending on the source, the replaceable filter is good for 264-500 gallons.  I also found a recommendation that it should be replaced annually.

Love this water filter - it has served me well on several back-country trips. There is no off taste and the collapsible bladder keeps everything small and compact
