Flex 700 ml

LifeStraw Flex is a collapsible squeeze bottle with a water filter that makes contaminated water safe to drink.

The advanced LifeStraw technology provides two-stage protection against most waterborne diseases. The membrane microfilter removes 99.999999% of bacteria, 99.999% of parasites and 99.999% of microplastics (lifetime 2,000 L). Replaceable activated carbon capsule reduces lead and chlorine, improves taste, reduces bad odors and organic chemicals (lifetime 100 L). LifeStraw can provide up to 5 years of safe drinking water with proper use and maintenance.

You can use it as a personal straw to drink directly from rivers and streams or fill the bottle to use your LifeStraw on the go. The Flex bottle is ultra-light and packs into a small space. Ideal for travel, camping, trekking, survival and daily use.

Here's how it works:

LifeStraw's membrane microfilters are made from hollow fiber membrane technology – a similar technology used in kidney dialysis. These membranes are made of tiny straws that contain microscopic pores 0.2 micrometers in diameter. Dirty water enters one side of the straws and clean water passes through the pores, while bacteria, parasites, microplastics, dirt and other types of turbidity are blocked and unable to pass through because they are too large. The result is that safe drinking water flows into a clean chamber for drinking while contaminants are blocked.

LifeStraw Activated Carbon filters improve the taste of water by removing chemicals like chlorine and odors. The activated carbon has been treated with specific processes to open millions of tiny pores between carbon atoms. LifeStraw uses an advanced, special formulation made from fiber instead of traditional granular carbon, which improves longevity and performance. This process works via adsorption - pollutants are trapped inside the pore structure of the carbon and bind to the surfaces of the fibres. Over time, when all surface areas are full, the carbon filter must be replaced. Note the longevity recommendations for each product.
