LifeSaver Liberty™ Ersatzkartusche

As a budding Prepper this seems like a very well designed and useful piece of kit and easy to use. The scavenging hose might be very useful as the water sources close to me (within a mile) aren't all that accessible: I don't really want to have to climb over a barbed wire fence, climb into a ditch or fight my way through brambles to fill my water bottle.

On the face of it, this bottle is expensive, but, given that it is a portable solution to purifying water, then it is actually worth its weight in gold.

There have been occasions when we have been out hiking and run out if water, so, this bottle gives us peace of mind that we can safely drink riven water if needed.

I have primed the filter and given it a test run, and the water tasted like, well, filtered water.

It claims to be able to purify 2000L, which would give you 5000 used at 400ml. I am not expecting to get that many uses, but even if I got half, I would be very pleased.

This LifeSaver Liberty is a serious piece of kit. The ability to remove viruses, not just bacteria, is why I chose it for my travels to remote areas. It's robustly built, and the pump action is straightforward once primed. The included scavenger hose is a brilliant addition for filling from difficult sources or topping up other containers. Yes, it's an investment, but for truly safe water anywhere, it's worth every penny. The 400ml capacity is for personal use on the go; use the hose for bulk filtering.

Although it's expensive, there really isn't a substitute for clean water. If you're planning on travelling anywhere where clean water is not a guarantee - especially out in the wilderness - it might be the best £120 you've ever spent.

It's very simple to use once you've done it a few times and although you don't need to use the hose, it's handy having that option available. As a lightweight, easy to carry solution without the hose, it comfortably purifies just under half a litre of water from pretty much any source. Although using the hose makes it less portable, it also makes it much easier to collect water from pools or similar.

Although I'm only really able to test this using household water (collected rainwater), I can confirm that it seems to work absolutely brilliantly. The water from it is clear and tastes pure. I don't know of other solutions or how they compare in terms of performance or price. However, as a portable drinking solution for anyone who's going to be away from clean water sources for a substantial time, this seems to be an excellent and potentially life saving device.

This is a remarkable product from LifeSaver which saves an incredible amount of time and effort purifying water and taking care of 1 of the 3 basic things you need for survival. A clean water source in my opinion is the main one, next is food then shelter. Back when I was a lad I was also in the scouts where I learnt how to forage and live of the land, setting snares and skinning rabbits became second nature as with shelter building for when tents we not available and obviously water collection and purification. The two methods we focused on was purification by iodine and sterilisation using Boiling water these would mostly destroy all bacteria and microbes, but does not remove chemicals or toxins.

This LifeSaver bottle can be used in two different ways, the first is a drinking bottle where you fill the bottle with dirty water and filters as you drink. The other method which is my preferred method is to use it as a pump to fill a secondary container. My back pack has a water skin inside with the straw/drinking pipe leading down the right shoulder strap making it easier to drink on the go. I simply use the bottle as a pump that filters the water into another bottle which I then use to fill the skin and the bottle. A brilliant feature is the water stop switch on the side it allows me the time I need to fill the skin without having to start all over again when I want to fill my other bottle.

I read that the filter should filter up to 2,000 litres and is designed in such a way that the bottle will stop working the moment the filter needs to be changed, this gives piece of mind that the filter will always be doing its job. I looked up where to obtain the replacement filter and the how to videos on the LifeSaver website. The filter is in two parts which you can change separately as and when you need to which helps reducing the costs. Overall it fells like a high quality item that has been designed for the end user and longevity in mind. The carbon filters come in packs of 3 and the ultra fine filter can be cleaned and would only need changing when the water flow stops and wont work even after cleaning.

Although it feels expensive it honestly isn't, it works out around £0.06p per litre which is filtered by your own hands the active carbon filter removes all the odours and bad taste as well as many of the unwanted nasties. Replace carbon filters are £15 for a pack of 3 and the ultra fine filter is £60. I do not know how long the ultra fine filter will last, all I know is that you can clean the filter many times over.

It is a fantastic product, one which is highly recommended.
