To maximize the lifespan of a cartridge, always choose the clearest water. GeoPress® cartridges deliver ~350 cycles (250 liters / 65 gallons) while UltraPress® offer ~300 cycles (150 liters / 40 gallons). Water quality matters; avoid silt and sediment. Preemptively filter out silt and sediment with a handkerchief or t-shirt to extend the life of a cartridge.
The time it takes to press with your GeoPress® or UltraPress® will gradually increase over time. We recommend replacing the cartridge once the 'press time' reaches approximately 25 seconds (or three years have passed since the first use). Please note that colder water may require longer pressing time and does not necessarily mean the cartridge needs to be replaced.
An unused and airtight cartridge can be stored for up to 10 years. Once opened, use it for 3 years or until press time is ~25 seconds.
GeoPress® and UltraPress® cartridges filter and purify most freshwater sources. Avoid using them with salty or brackish water. When treating freshwater, start with the cleanest water available, such as streams and rivers.
Grayl's activated carbon effectively adsorbs many chemicals, pesticides, herbicides, heavy metals, etc. However, it is not designed for industrial disasters, coal ash spills, high lead levels, mercury, nuclear disasters, high tannin concentrations, or water with toxic blue-green algae (e.g. cyanobacteria). Find another water source in those situations.
Grayl cartridges are designed to remove low levels of chemicals, pesticides, herbicides, heavy metals, etc., but are NOT designed to protect against industrial disasters, coal ash spills, very high lead levels, mercury, nuclear disasters, high tannin concentrations or water that contains toxic blue-green algae (cyanobacteria). In these conditions, it is very important to find another water source.
Grayl® cartridges contains non-woven ceramic fibers that have a high electropositive charge. These fibers effectively block and trap microorganisms and particulates, ensuring that submicron contaminants are removed through electroadsorption. Additionally, the cartridge is equipped with ultra-powdered activated carbon, which efficiently adsorbs chemicals, heavy metals, bad flavors, and odors.
To avoid contamination, use the Spout Cap. If dirty water comes in contact with the Inner Press, wash the Grayl (not the cartridge) with soapy water and rinse thoroughly. Alternatively, dilute contaminants by pressing and agitating water through a GeoPress® or UltraPress® purifier bottle 5-7 times.
Proper maintenance for your GeoPress® or UltraPress® is crucial for optimal performance. After your adventures, ensure to follow these simple steps to keep your purifier in top shape. Start with a 'dry press' by pressing the wet purifier into the empty Outer Cup and disposing of excess water. Next, remove the cartridge and allow it to air-dry for 2-4 days. For the remaining components, hand wash them with warm, soapy water and let them air-dry. To maximize the lifespan of the cartridge, store the unit assembled. With proper care, the cartridge can last up to three years.
Yes, experience the hydration benefits of electrolyte-infused water in a UltraPress® or GeoPress® when equipped with a One-Way Electrolyte & Drink-Mix Valve (available since April 2023).
Always add electrolytes into the clean drinking water side. Avoid adding flavoring or electrolytes directly into a cartridge not equipped with a One-Way Drink Mix Valve, as it can diminish the cartridge's lifespan and efficacy. In those situations, pour the clean drinking water into another water vessel and then add electrolytes or flavorings.
Size, capacity and weight!

Coli, Cholera, Salmonella, Dysentery). They also filter many heavy metals, chemicals, and microplastics.

Reviews
My EDC
"My Geopress, is a fantastic piece of kit that I use daily replacing the need for disposable plastic bottles of water. I use my Geopress exclusively in my travel from Colombia to the United States and everywhere in between. Most recently the Geopress provided safe drinking for me and my family in the most devastating areas of Colombia affected by the 7. 4 earthquake. Our friends were so impressed we actually bought them 2 complete sets of Geopress 24oz bottles with additional filters to use on their finca."
Good system- Removes Viruses
"Removing viruses is the big draw. Quality parts that stand up to outdoor usage. This is a perfect set up for fresh water supply to 1-2 people for a trip. I have used it for 3-4 people on a trip but it took a few fill ups. Minor inconvenience for "free" water in my opinion. I recommend it but wait for a deal day to get a reasonable price."
Great for Backcountry Hunts
"Worked great on a 10 day backcountry hunt. Yes, it’s heavier than I’d truly like, but we were able to filter large quantities of water with ease. Great product, I’ll gladly tote the extra weight around for the ease of use and speed."
It’s about time
"What an amazing product, I’ve used it twice in two mountain streams that both looked beautiful but would definitely make me sick without proper filtration. However I was able to safely get my natural water fill with the filter and enjoyed the most refreshing sip of great water I’ve had in a long time."
Great system, tried and true.
"This is my 2nd set up from grayl. Super easy to use! Only got 4/5 stars because I thought the ti container had an easy spot to tie off to retrieve water from hard to reach spots and the one I received did not have one."
Must Have!
"I've been using the GRAYL GeoPress for a few years now on my Adventures across the country. I helps me feel more confident when I'm on my hikes or at camp. If I want clean drinking water without having to boil it first I reach for the GeoPress. For me this is a must have. I believe in this product so much that I made it a point to purchase one for everyone in my family and a few for my nieces and nephews."
A Leaker from the start
"The seal around the filter never did seat correctly. It was defective from the first time I used it. A product should work straight of the box with no trouble shooting steps required."
Love how it is an
"Love how it is an instant purifier. But, I have smaller hands and I find it hard to grip and pull the inner cup out, when you need to refill it. In hindsight, I should have ordered the smaller size. I really don’t want to spend even more money to buy another one."
Waterbottle
"I purchased this waterbottle for an upcoming trip to South America. I tried it out with our very nasty Nevada water and was amazed that it actually took all the taste away. Lookung forward to trying it on our vacation! It is a little difficult to use (I'm a senior), but well worth the effort."
Q&A
- Is it possible to buy the new outer cup with the bevel by itself?
- Yes, we have a full assortment of replacement components available on our website.
- What’s the difference between nature and covert?
- Thank you so much for reaching out. Nature and Covert are just collections of different colors.
- I feel like I already know the answer but… I have a geopress and I thought the filter was dry so I reassembled the bottle. 1 year later (today) I pulled the cartridge out and it’s still damp. Do I need to replace it? If I filter a a bunch will it clean the filter or do you think bacteria has grown?
- Thank you for reaching out. Because the filter was stored damp for such an extended period of time, you will need to replace it before continuing to use your Grayl.
- Will it filter sulfate out of water?
- At this time we currently do not have any testing data related to the removal of sulfate.
- Does the GeoPress come with a filter/purifier cartridge, or is that sold separately?
- Every Grayl purifier bottle comes standard with a purifier cartridge preinstalled.
