Reviews

YUMMMMMMM

"I bought my UltraPress Purifier for overlanding and hiking. But now I also use it at home. I am on a well and my water is “safe” but has a ton of minerals that do not taste good. I have a whole house filtration system and another filter on my spigot. The water still isn’t tasty. I filtered it with the UltraPress Purifier and it is a game changer! It tastes sooo good! You also do not get that weird filter taste. I 10/10 recommend. I not only would recommend it. I already have to all the people on my well."

Michelle B. (5/5)

The best and most functional water filter you can take on any adventure.

"Small size and low weight make it perfect for hiking, and the bright color adds extra visibility!"

Oleksii F. (5/5)

Loving it so far! Traveling

"Loving it so far! Traveling in parts of Eastern Europe where they say the water is ‘safe’ to drink but why chance it. The Grayl 16oz bottle is the perfect blend of ease of use coupled with small size. In less than ten seconds we can get fresh filtered water from virtually any source without fear of bacteria or other bad things. Very happy with my purchase!"

Jeff B. (5/5)

My third Grayl

"I like the Grayl and trust it as a purifier. My one complaint is that the seal between the two main pieces eventually goes bad and then when you try to pour out the clean water, the unpurified water from the bottom chamber drizzles out with it."

Randy C. (4/5)

Perfect for travel!

"I travel for work and often find myself in hotels without access to clean, good tasting, bottled water. I don't trust the tap water many places I frequent, and those that do have sanitary water it often tastes horrible. Enter Grayl. It's the perfect solution to my dual safe and good tasting water problem. Very happy with my purchase and the 16. 9 oz size fits perfectly into my backpack!"

Chris J. (5/5)

Very hard to use

"I had to ask for help to pull the inner section out so that I could fill the outer shell with unfiltered water. Also it was difficult to push the inner section with the filter down, but at least that was doable and expected."

Teresa A. (2/5)

Perfect Size for traveling in unknown conditions

"We are traveling to remote locations in South Africa. As health concerns came to our forefront we purchased the 16. 9oz UltraPress® Purifier. It fits perfectly in our backpack and car drink holders. Easy to operate. Since speed was not a high priority the 10 seconds to push the inner bottle down with the filter into the outer bottle was not an issue."

Raj N. (5/5)

Great Travel Companion

"I used my UltraPress on a recent vacation in Colombia. It was reassuring to have the filtered water available at all times. And the water always tasted clean and with no funny flavors at all. It’s lightweight and easy to operate. One thing I wish it had is a connector from the cap to the lid. Too easy to drop the cap and potentially lose it."

Jane D. (5/5)

Great product!

"We use this when we travel anywhere, even domestically, and want to fill water bottles from sink faucet. The water tastes great and has no “chlorine” taste to it like most water does, which is one way I know it’s working! It works well, but does leave a little residual water in the unfiltered canister no matter how much I push down. Not a big deal I just discard it when finished filling bottles. Wish I would have bought a bigger one. Definitely still considering it. Highly recommend."

Amanda S. (4/5)

The GOAT

"This is by far the best water bottle ever made. I have struggled for years to find a water bottle for everyday life, that can filter out all the bad stuff. The ease and function of this bottle are second to none."
