Boost your GeoPress! GeoPress cartridges were redesigned in April 2023 with a new "core" and "flow channels" to accommodate a One-Way Valve for use with electrolytes, drink mixes and or other flavoured liquids.

Note: the GeoPress® One-Way Valve ships pre-installed in every GeoPress Bottle.

OVERVIEW

Replacement purifier cartridges for the GeoPress are designed to last 350 cycles (65 gal. / 250L). Lifespan will decline when purifying water with high levels of silt, sediment or tannins. Cartridge press time increases towards the end of the cartridge lifespan; when press time reaches 25-30 seconds, the cartridge should be replaced. Cartridge continues to protect, even as press time increases. Compatible with One-Way Silicone Valve for electrolytes and drink-mixes.

Reviews

Great for disperse camping

"Went on a extended trip into the wild with only the Geopress Ti for drinking water. Filtered from a muddy river with a lot of sediment without any issues. No taste to speak of. Ti version was high quality and looks to hold up for a long time."

Michael F. (5/5)

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)

My grayl

"I have not used it. I got the extra filter for when I need to replace mine so I do not have to wait during an emergency. I have a back up filter on hand."

Denise S. (5/5)

Geo water bottles

"I don’t like the bottles they’re too hard to take apart to refill not eco-friendly I want to return the bottles"

Paul P. (5/5)

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."

Colton H. (4/5)

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)

Excellent product! The Titanium version

"Excellent product! The Titanium version doubles as a cooking vessel!"

Q&A

Hi, I live in Switzerland and have just realized that there are two different models available for the geopress purifier filters and I was wondering if they are both original parts. The one model is the one shown on your page where the openings for water are arranged in groups of 6 horizontal slits. In the other one the openings for water are arranged in groups of 3 vertical slits. I just don't want to pay for some cheap copy of your product which is labeled with grayl. Thank you for your help.
Thank you for reaching out, and great question. The filter with the vertical ventilation slits is a first generation filter, while the one with horizontal slits is second generation. They are functionally identical in every regard with the only difference being that the second generation filter is also compatible with the one way drink mix valve.
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.
