## 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: Fester filter - Seems to work fine, convenient.
Review: No plastic taste - My number one positive for the Lifestraw soft bottle is that unlike most soft bottles, it does not infuse a platicky taste into the water. It is sometimes difficult to assess how effective the filter is since you do not know if you woulde have suffered had you not used it and drunk the unfiltered water. Most recently I used my Lifestraw bottle during a trip to Bolivia where tap water is generally not considered to be drinking water, with no ill effects. A minor fuss is that the filter should be wet stored, in salt water solution, when not in use. I would also like to use this bottle without the filter when I know the water is safe but the mouth piece supplied is not ideal since it is basically an open hole with nothing to stop water spilling out without the filter in place. An optional bite valve would be great.

## 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.

### ⭐⭐⭐⭐⭐ Brilliant, safe hydration option
*by B***R on 5 June 2024*

I did a lot of research into which water filtration soft bottle would suit me. I needed something light and durable for long days trail running or hiking in the mountains, and decided this was the right one, as reviews attested to it being light, effective and durable. I've used it on two all-day trips since it arrived, and both times it was an absolute necessity. In fact, I ended up having to share my water with others who had run out of water and had no other option. I prefer to fill it from mountain streams or lakes but apparently you can even use it with standing water. It's a great bit of kit and I'm very happy with the quality and performance so far.
