Seattle, Washington (November 03, 2021) – Seattle-based GRAYL®, maker of innovative water purifiers purpose-built for limitless adventure and travel, announced today the launch of the UltraPress™ Filter and Purifier Bottle. Perfect for hikers, backpackers, and travelers seeking the most capable and packable water filter and purifier available. This brand-new bottle packs many of the performance features of the higher capacity 24 fl. oz. GeoPress into a more compact, pack-friendly 16.9 fl. oz size. The bottle is now available for purchase on, and through REI and specialty outdoor retailers throughout the United States. 

The UltraPress empowers adventurers of all disciplines to make their own clean, safe drinking water virtually anywhere in the world. Unlike common camping & outdoor water filters, the UltraPress protects against all waterborne viruses, including Rotavirus, Norovirus, and Hepatitis A, plus bacteria and protozoa in a quick 10-second press. It also filters out microplastics and many pesticides, herbicides, chemicals, heavy metals, eliminating unwanted tastes and odors. 

“Clean, safe drinking water is a fundamental element of life, and the key ingredient in adventures big and small,” said Grayl CEO and President Andrew Weber. “The UltraPress isn’t just a new product, it’s the result of tireless research, development, and testing that positions Grayl as an indispensable tool that provides self-sufficiency and peace of mind anywhere in the world.” 

The UltraPress is sized for any pack pocket and features a sleek, easy to use design suitable for individuals or groups in a multitude of outdoor activities. A driving factor in its development was to meet customers’ desire to have a versatile and user-friendly product with the highest level of protection and performance. The bottles’ hinged FlipCarry™ handle rotates 90° for easy carrying and allows for effortless OnePress™ filtration and purification. The multifunctional SimpleVent™ drink cap features a RiverFlow™ drink-thru spout that delivers a fast flow of water to quickly quench thirst and make sharing easy. 

“Our goal has always revolved around revolutionizing portable water filtration and purification,” said Travis Merrigan, Co-Founder and Head of Product Development. “The top-rated GeoPress needed a sidekick that could fit into any pack pocket or cup holder without sacrificing the performance that has won over hundreds of thousands of customers that depend on Grayl to empower their adventures—and UltraPress does just that.”  

The UltraPress retails for $89.95 and is available in nine fresh colors ranging from the landscape-inspired Nature Collection to the bold, yet subtle Covert Collection.
