Those of you who read our water purifier buyer's guide may recall the name GRAYL. We gave the company's Ultralight water purifier bottle our Top Pick award as a result of its excellent performance and easy one-press operation. However, the Ultralight bottle's relatively small 16oz capacity and simple screw-on cap were some areas we felt could be improved upon. GRAYL has now released a new water purifier that maintains many of the benefits of the Ultralight while also increasing capacity and adding a drink cap with a spout.

The GRAYL Geopress uses the same “fill, press, drink” operation — just scoop up some dirty water with the outer sleeve, place the inner press portion into the sleeve, and push down with your body weight to force water up through the purifier cartridge. Capacity is 24oz (710ml), making it 33% larger than the old Ultralight.

The Geopress purifier is said to take 8 seconds to purify a full 24oz of water, or 5L per minute. The American-made purifier cartridge lasts for 65 gallons (250L) before it must be removed and replaced. As with the Ultralight, this purification media removes viruses, bacteria, protozoa, heavy metals, chemicals, and particulates. More importantly, GRAYL says it meets the stringent purification standards set by NSF/ANSI, and has been proven to remove 99.99% of viruses, 99.9999% of bacteria, and 99.9% of protozoan cysts.

Ergonomic improvements to the Geopress include Topogrip non-slip surfaces, a Simplevent air release valve, and the new cap design that includes a pour spout and carry handle.

The GRAYL Geopress bottle is currently available for pre-order on Indiegogo at a discounted rate of $77 for a bottle, or $100 for a bottle plus one extra cartridge. After the pre-order phase, MSRP will be $90 and $120 respectively. The first Geopress bottles are expected to ship in April 2019.
