GRAYL Unisex's GeoPress Water Purifier

Works perfectly, have used it for tap water in a few central American countries and so far so good. Would recommend to everyone.

Fantastic innovative item. I've used the lightweight version multiple times before with no issues. This version improves on that item and with increased capacity and some comfort features, is certainly hard to beat. Couple this to the filtration capabilities which are unchallenged at this price point, makes this a true game changer. Slightly heavy, but is understandably robust because of it.

Such a good option to not have to take pre-distilled water out to last you for the day! I read a few reviews to make sure I got it right, saw some bad reviews which I think now come down to user error! There is a fill line on the outside, stick to it. Make sure the cap is half undone. Add the inner and push down from a height. I'm feeble up top so if I can do it in 8-10 seconds, anyone can!

It is a major improvement the original one the gripe is better and the new opening for the air to come off when you press makes it much easier to refill in the field. The quality of the water is great. Make sure you dry the filter part so will work well when you need it again.

Regarding the review complaining about the tape on the handle - it's there by design! The bottle is secured to the packaging it comes in with a cable tie. The tape is there to prevent the tie from rubbing on the handle causing wear. Why 4 stars though? It's because the design, while good, could still be improved. The plunging action is fine, it's the removal of the inner bottle from the outer which is the hard part. Basically, you are trying to grip a wide diameter plastic tube (the outer part) and pull up on another part with limited gripping areas (the inner part). They have helped the grip on the outer part by adding some grippy material, however this is only on one side of the bottle; it really needs to be on both sides. Then there's the inner / top part. It's hard to describe, but basically it's hard to get an effective grip on it due to its shape, size and design. You can try pulling on the handle part, but you're pulling off-centre and potentially risking breaking it (it wouldn't happen for a while, but it's bound to happen eventually given the forces involved). There are a few rubberised areas but they're low down on the lid (need long fingers or big hands) and have plastic parts above them with slightly "sharp" edges, so if you try pulling up from these rubber parts it can potentially be quite sore on the fingers. I suspect the separation of the parts might get easier over time (like an aeropress) and maybe I just need to find the right technique, but I also think this is something which can be improved on by design. Also, for anyone wondering about the size - if you happen to have a 1L Nalgene bottle, it's about the same diameter but a bit taller. Also, the large part of the top lid can be unscrewed for a faster pour / cleaning. If you are cleaning it with soapy water you'll need to unscrew the filter first though. Again, the filter is quite a large diameter and needs to be unscrewed by hand, so if you have small hands I can see this being difficult. Aside from these few gripes, it is a solid product which will undoubtedly last for years, if not decades.

Extremely durable, very well made, easy usage, and reasonably priced replacement filter.

Very handy. A bit heavy but great to feel safe when drinking water.

I received my Grayl geopress very fast, it only took one night to get to me. I have already carried out a few tests with the geopress and so far so good. The water tastes great and the bottle is quite light as an all in one purification system, it weighs in at around 480g which for me is pretty good. I definitely recommend for anyone who wants fast purified water anywhere in the world!

Fungerar som det ät tänkt. Den renar vatten :)

Die Idee dieses Filters ist super. Mit dem Becher entnimmt man Wasser und drückt einfach den Innenteil inklusive Filterkartusche in den Becher hinein. Das funktioniert gut und erfüllt seinen Zweck. Im Gegensatz zu anderen Filtern kommt hier auch Aktivkohle zum Einsatz, weshalb die Filterwirkung sehr gut sein soll. Ein Paar (verschmerzbare) Nachteile hat das ganze natürlich: Die Kraft die man aufwenden muss ist relativ hoch, aber machbar - das ganze Dauert ca 30 Sekunden. Die Filterwirkung lässt mit der Zeit nach (Aktivkohle nimmt Stoffe aus dem Schmutzwasser auf) laut Hersteller sind 350 Vorgänge = ca 250l möglich. Dann kann man den Filter tauschen - dieser wird fest auf den Innenteil gedreht mit einer Art Bajonettverschluss. Aufgrund der Filtergröße nimmt die Flasche ein Volumen von etwa einem Liter ein, die innere Flasche hält aber nur 700ml. Das gefilterte Wasser lässt sich dann jedoch gut transportieren und hält dank dem Verschluss gut dicht. Die Flasche hält dank einer Gummilippe sehr dicht - jedoch sollte man nach dem Filtern erneut den äußeren Becher abziehen - um z.B. den Filter von außen abzuwaschen oder Reste auszuleeren, dann lässt sich die innere Flasche nicht mehr in den äußeren Becher schieben - da der Druck der nötig wäre um die Luft durch den nun nassen Filter zu drücken sehr groß wäre!

Fait le job et c'est déjà merveilleux. Rien a redire ça marche. Je recommande.

The water that stays at the bottom (that isnt going through the filter) is leaking on the top when you drink. Also after 2 weeks it takes like a minute to press through the water putting all my weight on it.... In the first few days it went really fast and smooth. Does that mean my filter expired in like two weeks using daily 2-3 filtering????? I mean the purified water feels super clean, but the brand promises more lifetime for a filter than 2 weeks and I would also expect that. I only use it with tap water at home and in my workplace... :/

No es el filtro para virus más económico por litro (me encantaría que un cartucho me durará más meses dado que no es tan fácil de conseguir según donde ...para eso el lifesaver era mejor) pero es más fiable y después de años usándolo no se me ha roto nunca ni filtro ni ningún cartucho (con precauciones básicas como meterlo en el saco por la noche si hiela y guardarlo en la mochila lleno y mezclada el agua pa que no este tan fría ..
