GRAYL GeoPress Replacement Filter & Purifier Cartridge (Black)

this is a great product. almost instant gratification. just push no sucking and blowing a vein in your head.

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

Bought as spare for my GARYL bottle. Currently using the ona that came with the bottle without any issues.

Excellent product

My wife and I used these in the Amazon of Brazil for 2 weeks. It did a great job keeping us healthy. I trusted it with my life and it didn’t disappoint. I would definitely recommend this.

I like how easy it is to use.

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!!

Bought a geopress and spare filter, It pay to have a spare.

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.

Did a 3 night canoe trip down the namekagon river in northern WI, brought this with and didnt have any issues. Used it for drinking during the day and cooking at night, no stomach issues during or after the trip. Seems to work great, cant ask for more. Pushing water through the filter is a bit of a chore but not overly so.
