GRAYL GeoPress Replacement Filter & Purifier Cartridge (Black)

Great tasting

Life saving device on the trail.

This filter works awesome. No complaints.

Definitely a must have in your emergency bag.

it works as promised. unfortunately UPS decided that since i ordered this to receive on Friday they decided to hold delivery till monday. doesnt do me any good sitting at the UPS store when im camping where i needed it.

I got this filters to replace the original one we had for our Grayl Geopress bottle. We used it for a trip overseas and were pleased with the results. We like the size, which while big to pack is wonderful to have full to drink. We actually have no way of knowing if it did its job, but are trusting that it does. I rated it only 4 starts on ease of using because I couldnt push the device down when the water was in the bottle to filter it. My husband had to do that for us, but we are older and my hands arent as strong as they use to be. A younger person would probably have no problem and it does need to be that tight! I donnt under stand what Flavor has to do with it. ??

The only difficulty I have is with separating the cups when I want to refill or clean the bottle parts. My 74 year old hands find I need help with that. The pressing part is easy. This is a gift from my son and daughter-in-law for my birthday to take camping - a cross between tent and primitive camping as I do use some comfort items. I like the bright colors for they are easier for me to see - anytime. My next one I think will be blue. Pricey but reliable with a good safety factor. Addendum: It took five five cycles before the seals sealed. I let it sit overnight in pieces and this morning it seems to work properly. The next few days will tell me for sure if this particular cup system is reliable. I tried videoing the the run overs but by myself I was not successful. Thank you for your inquiry about my Grayl water bottle purification system.

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

I have had a geopress for over a year now and absolutely love it. Its an amazing product and definitely worth every penny. Grayl is also an amazing company. I recently bought a replacement filter for my geopress and had an issue with it so I contacted their customer support and informed them of the problem I was having. Not only did they get back to me in immediately the person that was helping me gave me help troubleshooting the problem to include personally making a video with instructions and a few tips to help me work through the issues. I am thoroughly impressed with their products and their customer support.

Great replacement for Grayl water bottles.
