Purifier Cartridge
We purchased the 24oz Geopress cup and an extra filter. Love the size. Love how the water tastes. I took one star off because I do find it a little hard to get the inside cup out to clean.

Great Replacement Filter
We use the GeoPress for Camping and Hiking. The replacement filter is easy to install and you are right back to the clean, pure water just like the original.

Short Term
While Grails filter remove and filter most things they don’t last long only 250 liters compared to the MSR guardian Wich filter 10000 liters it’s a small filter amount.

I Had A Msg In
I had a MSG in the Army tell me that it made the water in the water buffalo taste fresh and I was sold. Great for in the field and when you travel out of the country and not sure how safe the water is.

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.

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.

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.

Replacement Filter
Works just like it should, produces sweer, clean water. I wish it was bigger!
