GRAYLGeoPress Replacement Filter & Purifier Cartridge (Black)

Quick order delivery.

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.

This is a replacement filter for my Grayl GeoPress.

Great product!

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 couldn't 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 aren't as strong as they use to be. A younger person would probably have no problem and it does need to be that tight! I donn't under stand what Flavor has to do with it. ??

Manufacturer should make size easier to match the correct replacement filter to the correct size purifier.“GEOPRESS” is the 24 oz size. But nowhere on the packaging does it say if it is for 24 oz or for 16 oz. Probably should make them different colors to match the replacement filter to the correct purifier.

Weve been using Grayl filter over 10yrs internationally and domestic travel the filter is super easy to change we always have one ready! It saves you tons if money buying water at $5 a bottle sometimes plus you dont have to worry about the plastic which always seems to get heated and is when the bad stucc leechesnout into the water the most! Even if we didnt travel we would have this as emergency back up! Yes, im legit no give aways just an honest customer!!

I use this product as an emergency water filtration system. I tried it on my own well water and have been using it for a month or two. It started getting very tough to push down after maybe 20-25 presses (24 oz. bottle) and after as many more, it takes at least a minute or more to press down. This is supposed to handle 300+ presses (around 65 gal. water), and even though the water still tastes amazing, this is tap water. Clear tap water. It shouldn't be this tough to press after so few presses. It's most frustrating.Other than that, this is a stellar product. Great concept and function, and I even bought the Ultralight bottle as well.......mostly because I ordered those filters instead of the Geopress ones, so why not? It's only money lol

La calidad y uso seguro

Been using Grayl in some pretty sketchy lakes and rivers (backcountry) for years. Tastes great and never gotten sick

Die Wasserfilterflasche habe ich mir für eine Fahrradreise durch Afrika in einem Outdoor-Geschäft gekauft. Zusätzlich bestellte ich mir hier noch einen zusätzlichen Filter.Nach einigen Monaten der Benutzung kann ich nun sagen, dass die Flasche und der Filter sehr zuverlässig sind. Normalerweise habe ich einen sehr empfindlichen Magen und dennoch habe ich dank dem Filter noch keine Probleme bekommen.Das Wasser habe ich hierfür schon aus diversen Quellen entnommen: Flüsse, Seen und Leitungswasser, bei dem es hieß, dass man es nicht trinken soll.

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 ..

Fungerar som det ät tänkt. Den renar vatten :)
