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 flavored liquids. Note: the GeoPress(R) One-Way Valve ships pre-installed in every GeoPress Bottle. 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.

Reviews

Best tasting water!

"I love my Grayl water bottle and filter. As an avid hiking, it’s indispensable. It’s easy to use and lasts a long time. I even tried it in nasty tap water with great tasting water as a result. It is a great product!"

— Chris P. (5/5)

Great product

"Took this on my last backpacking trip and it was so convenient. Filters water way faster and easier than my Sawyer Squeeze. I also like that it helps with heavy metals since Colorado has lots of old mines and I'm never sure what might be contaminating the streams. My only issue with it is it's bulky and heavy, but I'll still take it with me anyway because you can't beat the convenience."

— Christopher M. (4/5)

Great for travel!

"We originally bought the Grayl Geopress Purifier for our backpacking and camping trips. Lately, we've taken it on all our travels - whether in the US or out of the country. Having the Geopress saves us from having to buy expensive airport or hotel bottled waters. Wherever we go, we have access to good tasting, clean water! We decided to have an extra cartridge on hand since we've been using the purifier so much!"

— Dianne S. (5/5)

Love this filter!

"Looking forward to more adventures with my Grayl water bottle and filter. It works so well on backpacking trips and I love the white water bottle because you can easily see the water level."

— Bridget S. (5/5)

Only lasted 5 days

"Did the North Coast trail with a brand new filter and after 4-5 days it became impossible to filter water. Yes, most of the water on the trail was colored with tannins, but Grayl’s suggestion to ‘find alternative water sources’ is basically saying that you can only use this $125 filter bottle in optimal clean water situations, which most of the hiking is not. There were no alternatives and I spent 15+ minutes(!) filtering one bottle. Outrageous for the price."

— M (1/5)

Great product

"World travel is my passion. Reliable, clean drinking water is a must! My Grayl water bottle has been with me to 30 odd countries leaving no plastic bottle waste or stomach issues!"

— Sallie D. (5/5)

Love the titanium shell and

"Love the titanium shell and cap a perfect combination with the filter"

Geopress Replacement Filter

"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!!!"

— Michael R. (5/5)

Awesome product!

"Great concept and equally good water."

— Sean P. (5/5)

Ease of use

"Lock in and filter then drink. Use a few times first"

— Simon M. (1/5)

Q&A

How long can the same filter be used (daily) without risk of fouling?
Great question. However, there is no actual hard and fast rule. With that said, if used daily, a great habit to adopt would be to perform a complete cleaning and drying every 10-14 days.
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.
