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 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 parts, 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.

"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."
"One of the best purchases I’ve made in a while. Just got back from a fly fishing trip out west where we fished the south fork of the snake, silver creek, and wind river canyon. It was nice to just refill my bottle any time I needed to trip on water tethering than having to go to the truck for it. I was filling up everyone else’s bottle to the point I think I am buying all my friends one"
"This hasn’t only been a great water bottle, but a wonderful tool to help stay hydrated in the most remote areas. I love camping, and I’ve been in areas where the water hasn’t been the most trustworthy. This bottle has helped me feel comfortable drinking that water. Even if you aren’t remote and you’re camping somewhere not entirely remote, if you have a water source near you, you won’t have to worry about drinking that water. That’s been very comforting to know. Highly recommend!"
"I already had one along with another friend of mine. We took it out camping, and it allowed all of us plus our six kids between the two of us to drink water cleanly. Then, I started taking it to work And the guys in the field we do commercial roofing. Keep running out of water while doing repairs or open work. But there's always a ready source of puddles or cold water coming out of an a c unit that needs to be cleaned to drink. So we all put our money together to buy twelve of them and it has worked out amazingly."
"Finally had the funds & a Discount to try this out. . . The Sawyer Squeeze Filter & CNOC 2L/3L are my go to, for Price & water sustainability, where you need several Litres of water per Hour. . . So for day to day use, the Grayl System, is a good option, but can't replace the time a Sawyer saves!!! Get the Price of the Filter down to $10 & it would be more feasible!!!"
"I got this to use on a trip to Bali and I’m so glad I did! I have used it the entire time and have had no issues. A great way to cut down on plastics and save a bit of money!"
"This was recommended to me by the YouTuber Eric Hanson. I’m planning on traveling to New Zealand from the USA and he mentioned that this was great for international travel. I love the idea and ease of use."
"I really like this product, easy to use and the water comes out clean and tasting great. I tested it in a trailside puddle alongside a logging road and it worked great! My only concern is that it can be a little difficult to get apart and push down, Not for me but for my wife who is much smaller. Other that that I love it,"
"For the size of a water bottle, you can have guaranteed protection from a bad day (or multiple days). My go to for overseas travel now."
"I have used it 7-8 times now and I’ll be the first to admit I probably shouldn’t of used it in that water the first time but it still worked amazing haven’t gotten any bad effects after filtering the water only thing is I i really like the bottle is there a sleeve or something I can use with out having the filter so I can use the bottle daily"
