Replacement cartridges
GeoPress family
The GeoPress cartridge fits both standard GeoPress and GeoPress Ti. It is rated for up to 350 cycles / 250 litres.
UltraPress family
The UltraPress cartridge fits standard UltraPress and UltraPress Ti. It is rated for up to 300 cycles / 150 litres.
Legacy Ultralight family
The separately named Ultralight Replacement Filter is described for the older Ultralight Compact Purifier. Do not choose it for a current UltraPress based only on the similar name.
One-way valve for electrolytes and drink mix
The valve sits on the clean-water side and prevents mixed liquid from flowing backward through the purifier media.
The FeroAdmin listing has two variants:
|
Valve version |
Published compatibility |
Construction |
|---|---|---|
|
GeoPress |
GeoPress with second-generation cartridge, from April 2023, with horizontal flow channels |
Six duck-bill valves; 12 g |
|
UltraPress / UltraLight |
Every UltraPress or UltraLight purifier cartridge |
Four duck-bill valves; 10 g |
Choose the version that matches the bottle and cartridge. Older GeoPress cartridges purchased between 2018 and 2022 are not compatible with the new GeoPress valve.
How to use the one-way valve
Purify freshwater according to the bottle instructions.
Confirm the correct valve is installed on the clean-water side.
Add electrolytes or drink mix only after purification.
Keep mixed liquid away from exposed purifier media.
Remove, clean, and dry the silicone valve according to its instructions.
The valve is listed as food-grade silicone and dishwasher safe. The purifier cartridge is different: do not expose it to soap or cleaning agents.
Cleaning and drying
Current product guidance recommends:
perform a dry press into an empty Outer Cup;
discard excess water;
remove the valve;
let both cartridge and valve dry thoroughly, typically two to four days depending on humidity;
wash the valve separately;
keep cleaning agents away from the cartridge.
How to identify the right part
Check four details:
Bottle name: GeoPress, UltraPress, or Ultralight.
Standard or Ti: this does not change the cartridge family.
Existing cartridge generation, especially for a GeoPress valve.
Product URL and selected variant before checkout.
When uncertain about an older bottle, compare photos and model markings or contact 68travel support before ordering.

What is not currently represented as a separate listing?
The live GRAYL brand lookup did not return separate parent listings for caps, outer cups, inner presses, or titanium cook lids. Availability may change, so use the live brand page or contact support for a part not shown.
Sources and limitations
Accessories do not expand the purifier’s treatment scope. GRAYL bottles do not desalinate seawater or brackish water and are not designed for industrial spills, extreme chemical contamination, nuclear incidents, or toxic blue-green algae.
Technical figures and operating limits on this page are based on GRAYL's published specifications and instructions:
These are manufacturer-published benchmarks, not a guarantee for every source. Press time and cartridge life vary with water quality, sediment, temperature, cartridge age, and user technique. Use suitable freshwater only: GRAYL cartridges do not desalinate salty or brackish water and are not intended for industrial spills, extreme chemical contamination, nuclear incidents, or toxic blue-green algae. Follow local advisories and choose another source when conditions exceed the manufacturer's guidance.
Frequently asked questions
Does the one-way valve improve purification?
No. Its purpose is to allow drink mixes on the clean-water side without backflow through the cartridge.
Can I put electrolyte powder into the dirty Outer Cup?
No. Purify first, then add mix to the clean-water side with the compatible valve installed.
Does GeoPress Ti use a different cartridge?
No. It uses the GeoPress cartridge family.
Does UltraPress Ti use a different cartridge?
No. It uses the UltraPress cartridge family.
Can I wash the cartridge in a dishwasher?
No. The removable silicone valve can be washed as instructed; the purifier cartridge must not be exposed to soap or cleaning agents.
