I love this filter. Fits

"I love this filter. Fits into my style of adventuring perfectly. You can take this anywhere, anytime. When I’m out filming it’s the first thing into the pack. Going on 5 years, no issues. Thanks Grayl!"

— Ben R. (5/5)

My go-to setup

"I love my Grayls. I use the GeoPress all the time and purchased the UltraPress for travel as it fits by bag perfect. I also gave one to my kids for hiking. Highly recommend, it is such a great product."

— Robert L. (5/5)

Staying healthy in rural Tanzania

"I’m beyond happy with this filter! I used it while traveling through rural Tanzania, Africa, and it gave me so much peace of mind knowing that the water I was drinking had been thoroughly filtered and was free of all the bad stuff."

— Bibiana H. (5/5)

These filters do the job!

"With careful prefiltering I get more than the 300 they say to expect. Sometimes I take the time to use a milbank bag, but I usually just have a cotton bandana held over the outer cup with a rubber band. The more you keep out, the longer the cartridge will last."

— Mark B. (5/5)

Grayl great. Cartridge iffy

"Love the Grayl. Worked initially like a charm but after 20-30 presses of “clear” water it became very difficult to press. I contacted grayl and they sent me two replacement cartridges, which was great. Love the product concept but wish the filter lasted longer."

— Jim J. (4/5)

Awesome filter

"Best idea ever for a simple, compact water filter that works in any conditions."

— Michael B. (5/5)

Quality Product

"Got the replacement filter for two older Grayl water purifier bottle. I ordered the the one way rubber insert on both. I like the option of being able to mix electrolytes:) This works great because it also allows easy filtration for cooking needs too!"

— Casey O. (5/5)

Quality filter, easy to use.

"The cartridge turned up quickly. So very easy to install and easy to use without any instructions."

— Lee S. (5/5)

Replacement filter with valve.

"The replacement filter with valve that I recently received is not as efficient as the original products purchased. The valve does not work effectively, resulting in a small leak back into the water reservoir. I am unsure why, but it is inferior to the original product. I would like to include an observation that the customer service aspect of dealing with the replacement of a valve was not of a standard I thought the company would provide; it was distant, and a lack of communication, as well as information, was needed."

— Paul B. (2/5)
