LifeStraw is a brand that manufactures water filtration and purification devices. The first product (the original LifeStraw) was designed as a portable water filter "straw". It filters a maximum of 4000 litres of water, enough for one person for three years. It removes almost all of waterborne bacteria, microplastics and parasites. A bottle was later developed which incorporated a LifeStraw cartridge into a BPA-free plastic sports water bottle. In addition to these portable filters, the manufacturer also produces high-volume purifiers powered by gravity that also remove viruses. These are designed for family and community use.
