Grayl “boosted the performance” of its GeoPress Water Purifier Bottle with a redesigned filter cartridge and the addition of a new One-Way Valve that allows for using electrolytes and other drink mixes—one bottle is all that’s needed to collect water, press to filter and purify, and add electrolytes for hydration.
Grayl introduced the One-Way Valve in November 2022 with the launch of its UltraPress Titanium model—a water purifier bottle that is drink-mix ready and useable for cooking, filtering, and purifying water. All Grayl bottles will be drink-mix ready this spring with a pre-installed one-way drink valve.
Grayl’s new GeoPress One-Way Valve is removable for easy cleaning and “protects the integrity of the filter media, which would otherwise become clogged from drink mixes (or other flavored liquids), to ensure optimal performance when filtering and purifying.”
“Being able to add electrolytes quickly to freshly filtered water on the go, in the same bottle, is a revolutionary change,” said Travis Merrigan, co-founder and VP of product for Grayl. “After receiving a ton of positive feedback from product testers of our ‘drink-mix ready’ UltraPress Titanium Bottle, we decided to add this valuable upgrade to all GeoPress and UltraPress bottles without increasing prices. Having one bottle that can do everything—filter, purify, add electrolytes, and even use for a post-adventure cocktail or beer mug—is something only Grayl can offer right now, and we’re excited to bring that extra versatility to our customers.”
All Grayl water filter and purifier bottles feature Grayl’s patented press-to-purify technology, which removes global waterborne pathogens (viruses, bacteria and protozoa) and filters out heavy metals and chemicals, including lead and PFAS.
