OVERVIEW
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. Compatible with One-Way Silicone Valve for electrolytes and drink-mixes.
A One-Way Drink Mix Valve prevents water from reversing direction and flowing back into the filter Cartridge. Allowing the use of electrolytes and drink mixes, a feature unavailable in any other drink-thru filter bottle.
Firmly grasp the Inner Press. Rotate the cartridge (lefty-loosey) until it separates from the Inner Press.
Firmly grasp the Inner Press. Insert cartridge into the bottom of the Inner Press.

"I bought this as a gift, so I haven’t personally used it and can’t comment on its functionality. However, my first impression is very positive. It looks high-quality, well-made, and just as described. I’m very happy with the purchase."
"Great bit of kit but it has not been delivered. GLS say the attempted delivery but I was here all day and no sign. I am considering buying a bottle carrier and maybe upgrading to titanium but if I cannot receive items maybe I will look elsewhere."
"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!"
"It's pretty difficult to remove the existing filter from the Grayl bottle. But I am glad I have this backup and the filter itself gives me peace of mind that my water is clear of viruses."
"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."
"I first saw the Grayl filter on a YouTube channel about the government advice to store water. It is reassuring to know this will give me extra water over any bottled water I have managed to store."
"It is incredible that Grayl has figured out a way to filter and purify of water. Rapidly with a replaceable cartridge, I will definitely continue to use this product."
"It is the best filter out there. It is small, portable and complete; easy to use. The obvious choice in water filters."
"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!"
"I’m a backpacker and through hiker, and being able to drink from a water source without being concerned about chemical pollution is definitely something that can make or break a trip! hopefully this will be taken as constructive criticism, but I think that a larger water reservoir and larger push surface for filtering in a bigger bottle would be a lot more enjoyable to use as the frequency of filtration for a person who drinks 2+ gallons per day while hiking is many times per day. There’s not always water sources where I am and being able to connect the water filter screw cap to my other 28 mm attachments such as a connector or spout for hand washing that fit on a sawywer, on the grayls cap would drastically improve this item’s usefulness. Also it’s not perfect. The first time I used it the water tasted off and made me nauseous, but after filtering twice was totally fine. The bottle may benefit from a better or bigger filter… But if you’re water source is Sus af filter the water twice that works but it takes longer and u lose a little water each time to spilling!"
