GRAYL GeoPress 710ml Water Purifier Bottle - Filter for Hiking, Camping, Survival, Travel (Bali Blue)

Great bit of kit excellent filtration

This product can't be used with tannin rich water - which I only discovered AFTER I bought it. £100 wasted. I've given it 1 star only because I can't give none.

It's a really useful piece of equipment and could save your life

Well made, easy to use. We bought this for travel - not for backpacking (it is pretty heavy). We have been using it for tap water in countries where it is not safe to drink. The design makes it very easy to use and the separation between dirty water and clean water works well. The quantity of water produced is good and given it takes less than a minute it is very practical. The filter is easy to fit and remove and has lasted us so far. I can only say we have not got sick as to its effectiveness. There is some chlorine in some of tap water and this has removed the taste. It is not cheap but I think it is certainly worth the money.

Lo compre porque estaria en una expedicion en un cañon por 5 dias, la relacion calidad precio es lo mejor, nos evitamos llevar cargando agua para todos esos dias o esperar encontrar manantiales, con este filtro solo era cuestion de tomar agua del mismo rio y filtrarla, no tuvimos malestares en el estomago, y su resistencia es increible, ya que estuvimos pasando por rapidos y golpeando constantemente el producto y resistio sin problemas, solo algunos raspones normales

Leí que mucha gente dice que se cuela el agua al presionarlo … creo que todo radica en hacerlo con cuidado. De cualquier manera siempre hemos de llevar agua lista para tomar y no depender sólo de lo que el bote nos provea.

Llevo usándolo un año y sin rasguño alguno…

Poco práctico para llenar y al beber gotea. Para identificar el cambio de término tampoco me resultó tan claro.
