GRAYL GeoPress Replacement Filter & Purifier Cartridge (Black)

These cartridges do a great job removing bad tastes and impurities. Used one for tap water all over Thailand and never got sick (except when I bought an iced coffee on the street in Bangkok and forgot about the ice in it).

Expensive, but good. If I was stuck in the middle of nowhere, I would choose this for water filtering. You need the water bottle to attach it to, so the price adds up.

Had to get this replacement filter because I left my bottle full of water ,and even after washing/rinsing the bottle my water had a funny taste. After replacing the filter the water tastes fine. Dont be like me and leave water sitting in your bottle, or youll need to get a replacement filter too!

I liked this product because it’s a great quality water filtration product that is small to pack in trips for a back up for emergency water.

I like how easy it is to use.

When I first started researching for a water filter to use for a trip to multiple countries in southeast Asia, with widely varying levels of water quality, I assumed those straws would be more than adequate . After reading up on them, I realized that I needed more. The Grayl fit that bill...and did the job that would end with COVID-19 shutting things down a couple of weeks after that trip. Subsequently, on my return to normalcy, Im much more aware of germ breeding grounds...specifically public water fountains at amusement parks. While a filter will easily do the job, with then additional knowledge of what a purifier can do with water in much worse condition, why should I not continue using a superior product? Yeah, though potentially overkill, its going to cost more per use, but you only have your health, and those of your loved ones. Why compromise when you know youre safe to drink away, virtually anywhere, in good health? You pay for what you get. If this product is within your means, and meets your wants and needs, then pull the trigger and purchase it. You will not be disappointed in that Grayl.

Llevo varios años usando el sistema Geopress de Grayl, no tengo ninguna queja. Super recomendado. Lo utilizo en los bosques de tropico humedo del sureste nicaragüense.

I absolutely love this filter. No more buying gallons in plastic jugs, makes my house water better and its my backpacking filter on trips now. Heavier than the sawyer squeeze but I trust it so much more. This replacement filter worked great

Gr8 product and i use it daily
