Reviews

Geo press cartridge

"I purchased additional cartridges for my bottles. I am stocking up for the future and will buy a couple more soon. Product is very easy to use and takes up very little space in your luggage or carry-on. I travel overseas with these bottles and have clean water everywhere I go. With the uncertainty of the water supply with mother nature events and everything else going on in the world I am confident I will have clean water wherever I go."

From Everyday Carry to Thru-Hikes — My Go-To Water System

"I absolutely love the Grayl system and honestly use it every single day. For long thru-hikes, I carry the 16 oz titanium version for cooking, and paired with a PocketRocket, it’s become my go-to setup — simple, lightweight, and really all I need. I also use the larger plastic version for everyday use. After years of use, I can confidently say Grayl has become one of my favorite and most trusted filtration systems out there. Reliable, versatile, and by far one of the best water filtration systems I’ve used."

— Trevor H. (5/5)

Excellent Filter

"Backpacked the Paria Canyon using the filter from the few springs along the 40 mile hike. It worked great but it takes longer than 8-10 seconds as they state. More like 25-30 seconds and that’s from clear water and a new cartridge."

— Tom P. (5/5)

Takes crap out of Aurora, CO munocipal tap water

"Tastes great. If the claims are actually real, what;s not to like?"

— Psybear (5/5)

Great filter.

"Awesome filtering capability. Used it for everything from creek water to tap water!!"

— lane t. (5/5)

"Great filter! These little things pack a punch. I have used bleach in the past and other name brands. You cannot beat the amount of water purified with much else. Simply fast and reliable. Thank you!"

Q&A

Is the inner press, top, and outer shell dishwasher safe?: All bottle components (besides for the filter), should be handwashed with warm water and soap.
Hi I was wondering if these filters are freeze safe for cold climates? If the water freezes in the bottle with the filter is the filter safe to use?: Thank you so much for reaching out. They are perfectly functional after a single freeze and thaw cycle, but are not viable after multiple freeze and thaw cycles. Precautions around freezing only apply to wet filters.
I see you no longer sell the blue filters, the ones that only treat for taste. Will you be bringing them back or are you strictly selling the purifying filters only?: In addition to being a purifier, the current cartridges are also filters. Meaning, they also improve taste (odor and color) as they are loaded with ultra-powdered activated carbon.
What is the difference in the orange filter and the black one? Other than color.: Thank you so much for your question. There is no difference between orange and black replacement purifier cartridges other than for the color.
What is your disinfection agent to safely ingest water after it has passed through your system: There is no disinfecting agent after water has passed through the system. The water being filtered is purified by the purifier cartridge itself during the pressing process, not after. This is accomplished with the combination of electroadsorption and ultra-powdered activated carbon.
