A water filter is one more thing to carry, and so is a bottle. The LifeStraw Peak Squeeze is both: a soft 650 ml bottle with a filter in the neck, so you can fill it from a creek and drink straight away, or squeeze clean water into a pot. We paid $80 for the 650 ml version in Mountain Blue, and it weighs just 102 g.

What the filter removes
The filter is a membrane microfilter with a pore size of 0.2 micron. According to LifeStraw it protects against 99.999999% of bacteria such as E. coli and Salmonella, and it also removes parasites, microplastics, silt, sand and cloudiness. Those are the things that usually make you sick from a creek.
It doesn’t remove viruses, which are smaller than the pores, and unlike the LifeStraw Go Series 2.0 it has no carbon filter. So it makes water safe from bacteria and parasites, but it won’t take away chlorine or a bad taste.
The filter is rated for up to 2,000 litres. When it reaches the end of its life the water stops flowing, so you can’t drink unfiltered water by accident.

Five ways to use it
This is where the Peak Squeeze differs from a rigid filter bottle. The box shows five ways to use it:
- Drink directly from the mouthpiece, with the filter inside the bottle.
- Fill other containers by squeezing the bottle, so the filtered water goes into a pot, a mug or another bottle.
- Screw the filter on the outside of the bottle to get the last drop out.
- Use the filter as a straw on its own, straight from the water.
- Connect it to other Peak Series gravity systems.
You can also take the filter out and use the bottle just to carry water. Being able to squeeze clean water into a pot is the big one for camping: with a rigid filter bottle the water is only filtered on the way to your mouth.


The bottle and the cap
The bottle is made of a soft, thick material that LifeStraw describes as extra tough and leak-proof. There’s a “max” line near the top that shows how far to fill it. The cap flips off the soft mouthpiece and stays attached by its loop, and that loop takes a carabiner, so the bottle can hang from a pack or from the 4WD.
It’s hand wash only, so it doesn’t go in the dishwasher.



Size and weight
The 650 ml version is listed at 102 g with the filter and measures 10.4 × 25.4 cm. Empty, the bottle goes flat and rolls up, so it takes almost no room in a pack or a door pocket. A rigid bottle takes the same space full or empty.
650 ml isn’t much for a full day, so it works best where you can refill along the way. If you want more, there’s a 1 litre version of the same bottle, on Amazon and at Anaconda.

Conclusion: LifeStraw Peak Squeeze
The LifeStraw Peak Squeeze is a filter and a water bottle in one. It removes bacteria, parasites and microplastics, it weighs 102 g, it rolls up when empty, and you can squeeze clean water into a pot as well as drink from it. It doesn’t filter viruses, it has no carbon filter for taste, and 650 ml is small. I paid $80 for it. For hikers and travellers who want to carry as little as possible, it’s a very handy bottle.

Yes, if weight and pack space matter to you. $80 is a lot for a 650 ml bottle, but it replaces a separate filter and it rolls up to almost nothing. Prices differed between the shops when we looked, so compare before you buy.
