Grayl Geopress Replacement Cartridge

We just used these bottles in Tajikistan on a 5 day trek through the Fann mountains. We loved how quick and easy they were to use! Highly recommend.

The Grayl filter was key for our 100% success rate on our trip to K2 Base camp in Pakistan- kept our whole group healthy, hydrated and happy!

Our Grayl system has become our go to water purification system for individual and small group planning on our trips. I like being able to use just about any water source without hesitation to produce drinking water. We recently had a person fall out from heat exhaustion and we were able to setup a water team to keep producing clean water from the bitter, sulfur flavored well water that was available. Being able to make clean tasting water was important, got the person to keep drinking water and electrolyte mixes. The Grayl is our 'make water and pour into other containers' system (so no food contaminates in it). The Grayl was quick enough to train a new person on and get them pumping out the clean water which let our first responder stay on scene with our person in distress. Individual's recovery was successful.

I mean- drink water from the creek and rivers and lakes safely… what more is there to say.

Great product and works as advertised, very pleased.

It may work in storage as replacement I'll let you know in 10 years.

Anytime I leave home I pickup my Grayl. If I am going to the grocery store or a doctor's appointment I am covered with safe water. At a restaurant I pour the water served into my Grayl. To filter the public water normally served. No way would I drink from the water fountain or any other sorce.

Easy to install. Seems to do the job as advertised.
