It’s also worth noting that the slimmer filter on the UltraPress has a slightly different attachment mechanism to the GeoPress filter. It’s not just a matter of screwing it into place – or unscrewing it to remove it. There’s also a small plastic tab that you need to pry open before it will unscrew. And you’ll need to ensure that the tab is clipped into place correctly when screwing the filter on. It’s fiddly but that’s a small price to pay for safe, clean water! RiverFlow® spout delivers a fast-flow of clean drinking water for chugging, filling hydration reservoirs and other bottles. FlipCarry™handlerotates 90° for effortless separation (Inner Press from Outer ReFill) and easy carrying; provides a large pressing surface when flat.

The GeoPress always felt bulky. Unless you’ve got hands like Dwayne Johnson, it feels super chunky, like you’re a child stealing from your parent’s flask. It’s not physically hard or uncomfortable to hold, it just doesn’t feel right. Ultra-powdered activated carbon filters particulates (sediment, microplastics) and adsorbs many chemicals, pesticides, herbicides, heavy metals, VOCs, flavors and odors. Removes waterborne pathogens including virus (e.g. Rotavirus, SARS, Hepatitis A, Norovirus), bacteria (e.g. E. coli, Cholera, Salmonella, Dysentery) and Protozoa (e.g. Giardia, Cryptosporidium, Amoebae).Filters: particulates (i.e. silt, microplastics, etc.); activated carbon effectively adsorbs chemicals, pesticides, heavy metals, flavors, and odors My first gripe about the UltraPress came on a morning I wanted to use the outer cup on a stove to boil water. I never got to that point because the outer cup didn’t fit on any of the stoves in our camp. It’s just too narrow.

All of the water from the outer cup has passed through the filter and is now inside the inner core. Open that top cap and enjoy.

Filters particulates (sediment, microplastics). Ultra-powdered activated carbon adsorbs many chemicals (including PFAS & VOCs), pesticides, herbicides, heavy metals, flavors and odors. Always try to collect flowing water for filtering – the faster, the better. Fast-flowing water has less dirt and sediment in it. The FlipCarryâ„¢ handle found on the UltraPress adds a shit ton of tech to the cap. Why? The FlipCarryâ„¢ handled provides an enlarged pressing surface when flat; rotates 90° for effortless separation and easy carrying. May not sound like a big deal but it is.

GRAYL Ultrapress Review

By buying any Grayl product, you’re giving your money to a company that cares about our planet and its people. I found that with the Ultralight, after a while the press became very difficult to press, especially with the sort of awkward design of the lid. Grayl made an improvement here in a big way. The UltraPress cap is wider so your palms can use a flat pad to press down without the top lid digging into your hand.
