LifeSaver Bottle Ersatzkartusche

I hope I never have to use it! However, a few years ago I had my water supply cut off for 5 days and my supplier (Anglian Water) were absolutely useless and just denied responsibility and provided zero support. I'm not giving it 5* because it doesn't have a scavenging hose and you have to fill the bottle manually. That means a 5 mile cycle or hike for me to the nearest river. However I've also bought the Liberty, which does have a scavenging hose, so I hope I've covered both bases : long life and versatility.

This is a great piece of kit for those who like to be prepared. For hikers or those wild camping this is something that should be kept in your backpack when out and about in case of emergencies. If, for whatever reason, you need to drink water that you have found in nature rather than carried with you, from a stream or pond for example, you need something like this. The filter removes viruses, bacteria, parasites, chemicals, microplastics and heavy metals leaving you with safe drinking water. It is really easy to use. Simply fill the bottle from the located water source and then drink as normal through the straw in the cap and the filters inside to the rest

In an emergency this little filter could save your life. Highly recommended for any adventurer. My only criticism is the cost. This is £174.99 (at the time of writing) which seems very expensive. Yes this could save your life however other options are available for a good chunk less in price than this. Due to the lack of value for money I have reduced my rating by one star.

LifeSaver Bottle Portable Water Filter and Purifier:

I've been aware of this product for about 10 years now but it may be much older.

You don't necessarily have to drink straight out of the bottle. You can pour the filtered contents in to something else if you like. Therefore using the 'Lifesaver' as a through-filter.

If you are in a desperate situation or can't get water in to the bottle easily, you can use the sponge at the bottom of the bottle to soak up water and then squeeze the contents in to the bottle. This may not be appealing, but I did say if you are desperate. So for example, if there is a shallow puddle on the side of the road that you can't get the bottle in to and no other water source nearby. You can dip the sponge in to the puddle and then squeeze the contents in to the bottle before following the pressurisation steps.

Because this is made out of plastic, you will have to be careful with it if using it out on the field. The last thing you would want is for it to crack.

I think the long term use-case of this product makes it worth while if you spend a lot of time out doors and are maybe traveling light. You will get a lot of use out of it before you need to buy replacement filters.

This is a great Prepper item to have at my disposal. I've taken it apart to see how it works and I believe the claims are accurate and I am confident it will be effective at making scavenged water safe to drink. In addition to this I think its built to a very good standard ensuring its outdoor and rugged capabilities. The only negative aspect per se its its sheer size and weight.

This is a very well-engineered filter and purifier bottle. The operation is simple: just unscrew the bottom, fill it with water, screw it back on, and use the inbuilt manual pump. The main filter is supposed to be good for 6000 L and the activated carbon filter for 250 L. A replacement carbon filter is about £8, and the main filter is about £90, so if you are planning long-term use, you will need to factor these costs in. The price at the time of review is £174.99, which is at the higher end but I believe it's resonable given the robust construction and simple design with minimum moving parts to get the job done.
