StandbyClearx Pro Portable Water Filter Straw, Standby Supply For Camping, Hiking, Travel, Emergency

【Four-stage mechanical filtration system】 Featuring a multi-layered structure comprising a PP cotton pre-filter, coconut shell activated carbon and a 1-micron hollow fibre membrane, this system physically traps silt, large particulate impurities and microplastics from freshwater sources; the activated carbon improves the taste and removes odours. 【Ultra-light, Compact and Portable Design】Weighing less than 60g, the slender, tube-shaped unit fits easily into rucksacks, emergency kits, car storage compartments or pockets; it requires no batteries or complicated assembly – simply sip as you would from a standard straw to obtain filtered water. 【High-Capacity Filter Cartridge for Long-Term Storage】The rated filtration capacity is up to 1,500 litres (400 gallons); it has no expiry date when stored in a cool, dry place, making it suitable for long-term storage in outdoor and emergency kits (it is recommended to replace the filter cartridge when the flow rate noticeably decreases). 【Versatile for Multiple Scenarios, with Some Usage Limitations】Suitable for freshwater sources such as streams, mountain springs, rainwater and tap water; ideal for hiking, camping, outdoor survival and household emergency stockpiling; can be used for direct drinking or in conjunction with water bags and water bottles; not suitable for seawater or water sources contaminated with chemicals or heavy metals. 【2-Piece Set】The 2-piece, high-capacity filter set to meet your outdoor needs.
