Key features

Hollow-fibre membrane: water is drawn through a filter that LifeStraw lists with a 0.2 micron pore size.
Bacteria and parasites: LifeStraw states that the filter removes 99.999999% of bacteria and 99.999% of parasites, and that it also reduces microplastics, sand and cloudiness.
Long filter life: the manufacturer rates the membrane for up to 4,000 litres (about 1,000 gallons) of water.
No power or chemicals: you simply suck water through the straw.
Light and compact: easy to carry in a pack, a glovebox or a grab bag.
Simple upkeep: blowing air back through the straw after drinking helps clear the membrane.

Who should buy it

The LifeStraw makes sense as a personal filter for day hikes, backpacking and emergency supplies, used as the manufacturer directs. It is inexpensive, has no moving parts and takes almost no space.

Understand what it does not do. According to LifeStraw’s own information, this model does not remove viruses, dissolved chemicals, heavy metals or salt, so it is not suitable for seawater or chemically contaminated water, and in regions where waterborne viruses are a concern additional treatment is needed. No filter can guarantee that water is safe in every situation; follow the manufacturer’s instructions and local health advice. As a straw, it only works where you can get your mouth near the water or into a container, and it cannot fill bottles or supply a group. Drawing water takes some effort, and a filter that has frozen while wet may be damaged.

What to check before you buy

Model: LifeStraw sells several products, including bottles with built-in filters and versions with extra filtration stages. Confirm the listing is the original personal straw.
Pack size: single straws and multi-packs are sold.
Colour: more than one colour is available.
Storage: read the manufacturer’s instructions for drying and storing between trips.
Destination: check the water risks where you are going and whether you need added virus treatment.

Confirm the current price and the exact pack size on the retailer’s page before you order.
