I took your advice and bought a Grayl for my trip to Turkey. What a lifesaver it was. Even the locals don’t drink the water, but with the Grayl we had safe and tasty water for the whole trip. Thanks, Ray!

I've already decided to purchase one it's one of those things I think that people could use all over the world it's pretty ingenious probably the best purification system out there right now. Yes I know that's subjective but this isn't a water filter it's a purification system there's a huge difference throw in a Milbank bag or something for straining outsilt and debris, sand junk chunks, and you have a system that will last

Great review! Clear and extremely informative. You covered everything! Thank you

Excellent review, I had the opportunity to observe it in use on an Elk hunt, Two of us had the Sawyer and one member of the party had the Grayl, The speed and ease in which he filled his water container was impressive!! Now I own one.

Great review. Thank you. I'm using mine for travel in developing countries and it is a life saver.

A great video! This was very informative.

Best review of this purifier on the internet.cheers

I'm using that code as soon as coyote Ti comes back in stock. Cheers for that!

Great product. We are under boil water restrictions as I type this. Good Job on video, very informative.

Great video. I am going to Portugal in the fall. Maybe I need one too!

Ray, thank you for your water purifier review. After watching your video, I purchased a 24 oz GeoPress purifier for myself (Illinois) and one as a surprise gift for my sister (Florida) on separate orders. I used the coupon code MARTINRAY15 and received a 15% discount on each order. I placed both orders Monday night, February 20. Both orders were promptly processed and promptly shipped Tuesday. Both orders were delivered Thursday morning. I didn't know my sister planned to purchase a water purifier to use while hiking in the Bighorn Mountains (Wyoming) this summer. She is very happy with the surprise gift. By the way, she agrees with Ray that the water in Florida doesn't taste very good.

Consider using adhesive to attach the cap to the handle with shock chord.

Not sure I'm ready for one yet, but I like it.

Going to Africa, I guess I will buy one.

Since you already have the geopress and the toaks ti pot, do they nest together?

Hi Rmarvids! Great review! This is probably the best one I've seen so far. I've been going through a bunch as I recently started looking into purchasing a GeoPress. I have a quick question if you don't mind. You touched on the shelf life of the filters and mentioned that when unused/unopened they will last up to ten years. So for the filters themselves, would that mean just leaving them in their original packaging or is anything else needed in order to reach that shelf life? For a newly purchased Geopress that would be stored for emergency use only, does it come packaged in a way where the filter can be kept airtight in order to maximize shelf life? I imagine being in the bottle would give it the perfect airtight storage spot, assuming there is no way that the cap was twisted loose in the packaging. I would be purchasing from an REI so I'm not sure if they're shipped or displayed in a way where other people can open and mess with them before purchase. Thank you!

I need a good water filter for a friend who lives in Africa. He is drinking water from a swamp well. In this moment he is boiling the water before drinking. What is your recommendation? Which water filter can you recommend in order to not boil the water before drinking. Thanks!

Does it filter out fluoride?

Informative video. Used MARTINRAY15 to purchase a Titanium and 24oz. Covert. Both are very nice. Filtration is amazing! Agree with updating the 16.9 screw cap so that it can’t be lost. I have to drink a ton of water due to kidney stones and normally have to cart water bottles with me. Now with the Grayl I can always have clean filtered water anywhere and anytime I need it.
