LifeStraw Personal Water Purification Filter Test and Review

LifeStraw Personal Water Purification Filter –  Test and Review 

man drinking from a lifestraw personal purification filterThere may be water everywhere, but would you risk just scooping it up and drinking it?

If you were in an absolutely desperate situation where you had nothing to drink for days, then maybe it’s a yes. If your life depended on it, then it might be worth the risk.

If you’re settled in a camp, intending to stay for a while, there’s always the old favourite of making a fire and finding something to contain the contaminated water in while you boil it up.

But what if your on the move and have no time for stopping and making fires and boiling water and hanging around?

Well, for anyone in that situation, and I’m talking hiking and trekking as well as prepping, you have to look towards modern technology to give you the answer.

That particular bit of survival technology comes in the form of the Lifestraw Personal Water Purification Filter.

Just recently I was sent the Lifestraw filter from my friendly survival gear suppliers at Silver Fox.

So it was straight out to give it a good test to see just what it could do.

This is my Lifestraw review:

lifestraw-personal-water-filter (1)The first thing that will strike you is, how dam light this thing is.!

At 2oz, a box of matches is heavier and initially you handle it with care, thinking something that light can’t be very strong – but don’t be fooled by that one, it’s a solid bit of kit.

Yeah, sure, hit it with a hammer and it’ll break, but the overall build is solid and tough, with the main body made from a rigid plastic and the mouthpiece and course water filter from a rubberised plastic, so a bit more supple.



lifestraw water filter specifications It’s a bit of a wolf in sheeps clothing really, in so much as, it looks quite unassuming and low key, as it has no moving parts, you don’t have to add batteries or wind it up or pump it or use any other way to make it work.

You simply remove the bottom coarse filter cover and the top mouth guard and you good to go – simple as that. No faffing around.

You can just lean down and drink from any water source you happen to find laying around.

How easy is that…..

All the technology is on the inside:

Inside the 9″ long body is a ‘hollow fibre filter’ that is capable of filtering out bacteria down to 0.2 microns in size.

To you and me that means small, small enough to stop 99.9999% of the bad stuff getting through – see the specifications here on the right >


Good points:

Without doubt its most noticeable feature is the weight – you can certainly carry it around all day and never notice you have it with you. This is ideal for anyone hiking.

It does exactly what it’s supposed to do.! In my field test, the filtered water tasted as good as bottled water.

The top and bottom dirt caps fit snugly, so even if you dropped it the mouthpiece wouldn’t get dirty.

Bad points:

I found one tiny problem, probably insignificant to most people but, the clip securing the neck cord to the top of the filter snagged on my jacket as I pulled it over my head and ‘unclipped’ itself.. Not a problem if carried in a rucksack, but just me being over fussy…


Overall conclusions:

It works, simple as that really.

Definitely gets a 100% thumbs up from me, in fact, after testing this one, I went out and bought another.

Currently selling for under £22 from Amazon, I think it’s an absolute bargain for 1000 litres of drinking water.

    Which is better, the lifestraw or the bottle water to go ???
    Price wise it’s the lifestraw but which ones purifies the water better Steve.

    1. Hi Rachel,
      I think the Water To Go is the better choice.
      It gives you a means of carrying water more easily, and also filters a higher level of contaminates, including viruses.
      Thanks, Steve

    Dont use on tidal water / sea water
    But i laugh seeing hikers with 3kg of water on back when a 2oz straw is good enough in most inland sittuations. Elastic band a bin liner(opened at both ends) over bottom. Turn upside down use like a large funnel to fill a bottle
