Lifesaver Water Filter Bottle – full review

Water Purification For Prepping
The Lifesaver Water Filter Bottle

There are a few choices when it comes to filtering and purifying water in a survival situation.

From making your own bushcraft style filter using rocks and sand, to building a fire and boiling.
But as preppers we all like to keep things nice and simple.

Hence, for that reason I am testing the Lifesaver 4000 UF ( Ultra Filtration ) Water Filter Bottle from the Lifesaver company here in the UK.

.I have never been much of a fan of fiddling about boiling up dirty water and adding various tablets and chemicals to try to make dirty water into clean drinking water.

Yes, I know it is still a choice and it’s something we should all have a knowledge of, but for me keeping things simple with minimum hassle has always been a survival priority.

Carrying bottles full of drinking water is a definite strain on yourself and your resources, after all you can only carry so much at any time.

So from a sheer practical point of view it makes sense to filter your drinking water as you go rather than try and carry or horde it.

The way I look at it is that I would rather have a stream delivering unlimited amounts of water, even if it is dirty, grubby and undrinkable water than have to keep trying to find and to keep carrying thousands of bottles.

In fact any water source will do – it gives you a relatively unlimited supply to draw your water from and will certainly make your life much easier.

In a survival or bug out situation it’s just one less thing to worry about.

When you received a Lifesaver Water Filter Bottle read the instruction fully. ( something I advise you to do fully and make sure you carry out the setting up and flushing procedures correctly ).

I also gave it the once over and, having read various reviews, also checked the bottom O ring seal to ensure it was in place and seated firmly.

Apparently this can come adrift and cause it to leak at the bottom – however, mine was perfectly fine and seated in the pump end cap. 

The filter bottle itself is about the same size as a standard 1.5 litre bottle and it fits nicely in the side pocket of my bug out bag – having set the lifesaver up I then set out for a field test – my full review from kitchen to smelly, grubby water test is in the video below:

The principle of the LifeSaver is quite simply really – You fill the bottle up from a water source [any water source will do *except salt water* mine was a nice grubby stream as you will see] and then the ‘dirty’ water goes through a course pre filter which catches odd debris like leaves etc.

When the main bottle is filled up [ the bottle holds 750 ml ] Replace the end cap and after a few pumps to pressurize the bottle you can release the drinking nozzle and the “dirty” water passes through the main cartridge and then through an activated carbon filter to give you clean, sterile drinking water.

Very clean, sterile drinking water actually – the cartridge has minute pores which can filter down to 15 nano metres – this will stop parasites, viruses, bacteria, fungi and waterborne pathogens and the activated carbon filter takes out the bad tastes, instantly…!

You can see this and more in the full video below - I found the final result quite amazing. 

The 4000 litre model costs under £125 inc VAT & delivery: 

The LifeSaver 4000 UF delivers 4000 litres of clean, sterile drinking water and when the filter has dispensed the 4000 litres it will automatically shut down – the filter itself is given a two year shelf life from the initial activation process which I simply done at my kitchen sink.

When the filter gets to the end of its 4000 litres of usable life you simply remove the old filter and replace it with a new cartridge –  new cartridge costs under £95 inc VAT & delivery – Lifesaver Systems Limited 4000 UF Cartridge,
This effectively gives you a complete new water filter and 4000 litres of sterile drinking water all over again.

 

Calculations & Costs based on 1 persons water requirements per day of 5 litres:

With the 4000 UF filter you will get 5 litres/day for TWO YEARS

*there is also a 6000 litre bottle available which give added value for money – prices below:

With the 6000 UF filter you will get 5 litres/day for THREE YEARS

The average price for a 4000 UF cartridge is £95 inc VAT & delivery – so that is equal to an amazing 2.4 pence per litre...!

The 6000 UF cartridge costs around £110 inc VAT & delivery which makes and even better saving of just 1.8 pence per litre…!

So this really is a huge saving when stocking up a water cache and trying to store bottled water at a bug out location.

* the Activated Carbon Filter will last for 250 litres – these are dead simple to change over when needed and with that in mind it’s worth investing in some spare filters along with the bottle – fortunately they are cheap and come in packs of 4 for under £20 inc VAT & delivery – Replacement Carbon Inserts (Four-Pack)

To match the 4000 litres capacity of the filter cartridge you would need 16 activated carbon filters.

 

 

 

 

Along with a couple of replacement cartridges I have also invested in a some of the course ‘pre filters’ to ensure I have all the main filters as  ‘spares’ for as and when I require them. Just a sensible precaution I think – the pre filters cost £12 for a pack of two – Lifesaver Systems Limited Pre Filter Discs (Pack of 2) – there is no real lifespan for these pre filters as they can easily be removed on thoroughly washed out and refitted, but I just wanted to know I had spares if needed.

Final thoughts:

The LifeSaver 4000 UF water filter bottle gets a big 10/10 from me – I didn’t find a single thing that I could give a bad mark to.

It did exactly what it said it would and has now proved to be a permanent addition to my survival kit

My advice to any anyone preparing for a survival situation, whether that’s out camping, hiking or prepping –  is to make sure you add one of these to your survival kit as soon as you possibly can.
