Reviews

Changed my life

"This product changed the Qualität of my life. I have a sulfit allergy and with this product I can trink every water. No matter how much sulfit is in the water. So I use it mostly every day. For example, when there is only mineral water that I can buy, I need it or when I visit another country, because there I don't realy know how much sulfit is in it. So with this product my hole life changed. I am not scarred anymore to trink something wrong."

Amazing bottle

"Love the geopress. I have a geopreas titanium and use the French press for it all the time. Filled my geopress directly out of lake Victoria in Kenya, streams in Honduras and well water in Africa. Works awesome. I have never been ill since I started using it. I filter local bottled water as well. Amazing product. I go everywhere with it."

— Casey (5/5)

Geopress filter

"My grayl ti's are always in my pack, weather it's my 16oz for day hikes it 24oz for multi day use I know I can count on clean, safe drinkable water where ever I go. Excellent products."

— Dave M. (5/5)

I had a MSG in

"I had a MSG in the Army tell me that it made the water in the water buffalo taste fresh and I was sold. Great for in the field and when you travel out of the country and not sure how safe the water is."

— Daniel K. (5/5)

Great for disperse camping

"Went on a extended trip into the wild with only the Geopress Ti for drinking water. Filtered from a muddy river with a lot of sediment without any issues. No taste to speak of. Ti version was high quality and looks to hold up for a long time."

— Michael F. (5/5)

Geo press cartridge

"I purchased additional cartridges for my bottles. I am stocking up for the future and will buy a couple more soon. Product is very easy to use and takes up very little space in your luggage or carry-on. I travel overseas with these bottles and have clean water everywhere I go. With the uncertainty of the water supply with mother nature events and everything else going on in the world I am confident I will have clean water wherever I go."

— Linn S. (5/5)

From Everyday Carry to Thru-Hikes — My Go-To Water System

"I absolutely love the Grayl system and honestly use it every single day. For long thru-hikes, I carry the 16 oz titanium version for cooking, and paired with a PocketRocket, it’s become my go-to setup — simple, lightweight, and really all I need. I also use the larger plastic version for everyday use. After years of use, I can confidently say Grayl has become one of my favorite and most trusted filtration systems out there. Reliable, versatile, and by far one of the best water filtration systems I’ve used."

— Trevor H. (5/5)

My grayl

"I have not used it. I got the extra filter for when I need to replace mine so I do not have to wait during an emergency. I have a back up filter on hand."

— Denise S. (5/5)

Geo water bottles

"I don’t like the bottles they’re too hard to take apart to refill not eco-friendly I want to return the bottles"

— Paul P. (5/5)

Excellent Filter

"Backpacked the Paria Canyon using the filter from the few springs along the 40 mile hike. It worked great but it takes longer than 8-10 seconds as they state. More like 25-30 seconds and that’s from clear water and a new cartridge."

— Tom P. (5/5)

Q&A

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.
Do your filters also filter Cyanobacteria and their toxins?: They do not. Areas where cyanobacteria are present should be avoided when using your Grayl.
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.
