You Can Cook Right Inside the Latest GRAYL Water Filter

GRAYL’s Titanium UltraPress makes a strong case for backpackers with lighter weight and multiple uses, saving space in the pack.

The UltraPress water filter from GRAYL was already a smash success. Its simplicity, ease of use, and compact design make it one of the most functional water filters available. It’s a hit with international travelers because it can filter viruses, something many water filters can’t do. But GRAYL didn’t stop there.

On Nov. 1, GRAYL drops a titanium model that stands apart from the crowded water filter market. That’s because, for the first time our team is aware of, you can now use your filter to cook.

That’s right. The system still uses the same press-style filter that everyone loved from the UltraPress. But now, the titanium outer vessel of the water press can go right over your camp stove or fire to boil water.

Fill, Press, Drink

GRAYL Titanium Water Filter

The filter functions the same as GRAYL filters always have: With one hand, grasp the FlipCarry handle and twist to remove the filter/purification component. Then, scoop water into the outer vessel. Press the filter/purification device back down onto the water. Pressure forces the fluid through the filter and in about 10 seconds (with a fresh filter), you’ll have a half liter of purified drinking water.

Activated carbon filters remove particulates like sediment and microplastics. It also removes waterborne pathogens like rotavirus and E. coli. (It improves the taste and smell of the water, too.)

It’s effective on all seven continents thanks to its ability to remove viruses, and the replaceable cartridge is rated for 300 cycles — or 40 gallons of water. Our personal experience, however, probably comes up a little short of that number.

All of that is the same in the UltraPress Titanium filter.

But the titanium version has one notable difference: the outer bottle is a titanium mug. Now, you can use that element to boil water, cook soup, make tea, drink beer, or use it however you’d use any other titanium pot.

GRAYL added two retractable handles to this version, so it’s easy to hold when full of hot liquids. It also has a micro D-ring so you can hang it over flames or coals.

A one-way silicone cartridge valve also makes it possible to add electrolytes or other enhancers to your water. The beverage will only flow in one direction, without compromising the filter.

GRAYL’s UltraPress Titanium ($200) will be available for purchase on GRAYL’s website as of November 1.
