GRAYL GeoPress Replacement Filter & Purifier Cartridge (Black)

Very easy to use. Revolutionary in its concept and design. Some R&D might need to be considered about how to reduce water source contamination remaining on the outside of the collection cup after dipping it in a water source. But overall, this is an extraordinary product and I highly recommend 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.

Top shelf !

Life saving device on the trail.

Simple product to use. Instead of having to carry separate purifier and cup or container, its all in one. Love it!

We travelled to Cancun, Belize and Honduras on our cruise. Took the Grayl and filter. We used our Grayl water bottle and water from Mexico on all of our excursions and never once got sick. We also didnt need to purchase a case of bottled water on our cruise ship, we used the Grayl water bottle and filled up water from our suite. This bottle and filter are so amazing that we have recommended it to our kids and friends for hiking, emergencies and travel.

Its a filter that screws to your cup, super awesome and great packaging. Love my grayl bottle.

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

Excellent product

I keep my GeoPress with me always..Since getting this, I no longer have to worry if the water is okay to drink or buy water in plastic bottles which is a pollutant.
