Lifesaver Bottle portable water filter

The LIFESAVER Bottle is the ultimate in portable water filters. This 750ml water bottle with a built in dual-stage filtration system allows anyone, anywhere to be confident they are consuming only clean, pathogen-free water.

A creation of UK inventor Michael W. Pritchard, the LIFESAVER Bottle removes all bacteria, viruses, cysts, parasites, fungi and other microbiological water borne pathogens through a central cartridge whose membrane consists of pores only 15 nanometers (nm) wide. With the smallest bacteria ranging from 200 nm and viruses at 25 nm, they simply can’t get through.

The LIFESAVER Bottle has been independently tested and certified by the London School of Hygiene & Tropical Medicine using E-coli and the Poliovirus in their testing regimen. This unique portable water filter also contains a removable carbon cartridge to eliminate chemical residues and heavy metals.

The LIFESAVER Bottle is lightweight, and with a flow rate of approximately 2.5 litres per minute, the 750 ml bottle fills as quickly as 20 seconds. The portable water filter essentially eliminates the need to carry water with you as long as any water source, however dirty, is available.

Depending on the cartridge chosen, the LIFESAVER Bottle can filter up to either 4,000 or 6,000 litres of water before replacing. The cartridge incorporates a FAILSAFE technology that ensures the system automatically shuts off when the cartridge has expired so you don't unknowingly drink contaminated water. 

Utilizing the same technology, a larger portable water filter, the LIFESAVER Jerrycan, is also available and can filter up to 20,000 litres on one cartridge, perfect for expeditions or even camping trips. The combination of these two portable water filters has been used successfully to provide emergency drinking water response for tsunami disaster victims in Japan and in Haiti and Pakistan, amongst other on-going projects.

The LIFESAVER Bottle can be purchased online and retails for $160 in the US, £120 in the UK and AUD$230 in Australia.

  1. Hi Guys, I just wanted to clarify one point in your excellent review and that is the retail pricing. In Australia the price of $230.00 includes all shipping to your door and GST. Whereas all of the other prices listed are the list price excluding any international shipping or postage and handling fees. Hence the apparent difference in price. I hope this helps clarify the price difference.

  2. wow, this is a really helpful thing when hiking, camping or surviving. I didn’t know that there are such “smart” bottles on market. but I still can’t get rid of unpleasant thoughts about how was that water dirty before filtering it.

  3. Dear Sir,

    Regarding the PR news on Thai flood, the company use this cause as a cheap marketing PR. The service they provided is among the worst I experience. The company donate only 55 units to a person. I import 105 units plus extra catridge 55 units. Many errors and delay in assisting to get my shipment srtive in Thailand. Also, They are not transparent to how they work on the humanitarian cause. I have sll emails exchanged as evidence. I do not want others be fooled as me.

  4. Wow it seems I have had the same experience. The service is very bad and they use tacky PR tricks to make you think they give a damn but all they are bothered about is making a fast buck! I heard that the Department for International Development are backing this company’s ethics by naming them as one of the rapid response network of 32 UK-based charities and businesses which will have access to funding within the first crucial 72 hours of a natural disaster. It seems others have already been fooled by them.

  5. Hi,
    Would love to talk to you both about the experience you have had with LIFESAVER – i am new in post and would like to know why you feel you have been ‘fooled.’

    Kind Regards
