The next generation 24 oz (710 ml) GRAYL GeoPress Water Purifier empowers international travelers, adventurers and survivalists to make clean drinking water-from the sketchiest of water sources-anywhere on earth! Unrivaled in speed, ease, and versatility, its patented OnePress Global Protection effectively removes all waterborne pathogens (VIRUS, BACTERIA, PROTOZOA) and filters pesticides, chemicals, heavy metals, and even microplastics. Convenient and astonishingly efficient, GeoPress purifies and filters 24 ounces of water in just 8 seconds (5L/min)-nearly 2x as fast as any other purifier. Works on virtually any contaminated freshwater source: sketchy spigot, hotel sink, jungle river, murky well, or lake. The unrivaled user experience is packed with innovative features such as a SimpleVent Drink Cap which 1) vents air during purification, 2) protects against cross-contamination, 3) allows one-handed hydration through a fast-flow spout; SoftPress ergonomic pads for comfortable and easy pressing; and TopoGrip for non-slip grip in any environment. BPA-free and independently tested to meet/exceed NSF Protocol 43 & 53 for pathogen & chemical removal, and meets EPA Guide Standard & Protocol for testing microbiological water purifiers. Purifier cartridges (one included) are replaceable and constructed of non-woven ceramic fibers that block particulates (i.e. microplastics, sediment) and provide structure for two technologies: 1) positively charged ions (i.e. molecular magnets) and 2) powdered activated carbon. As dirty water is forced through the purifier media, ion exchange permanently binds all waterborne pathogens (i.e. virus, bacteria, protozoa cysts). Ultra-powdered activated carbon adsorbs pesticides, chemicals, heavy metals, flavors, and odors. Cartridges rated for 350 cycles (65 gallons / 250L) and are recyclable through GRAYLs zero waste recycling program. Weighs 15.9 oz (450 g). Measures 10.4 H (26.5 cm) x 3.4 D (8.6 cm). 1% for the Planet Member.
