Snoop's Take

The GRAYL UltraPress 16.9 oz Water Purifier & Filter Bottle is designed for outdoor enthusiasts and travelers, providing a convenient solution for purifying water from various sources.

Overall, the GRAYL UltraPress is highly recommended for those seeking a reliable and efficient water purification solution in outdoor settings.

What it does well!

Key strengths users can’t stop talking about.

Fast and easy to use

“Best water filter to drink tap water abroad? Does anyone have a recommendation for a portable filter that will allow you to drink tap water in countries where it might otherwise be risky?”➕

“Grayl geopress. Incredibly expensive, but it's a container & filter, fast, easy to use, and the filter contains activated carbon which will improve the taste of the water in addition to protecting you from bacteria sized contaminants as well as viruses.”➕

“I really like the Grayl but have only used it about a dozen times so it is still easy to press. I’m curious to hear how soon it becomes harder to press and at what point others have elected to replace the filter.”➕

“Someone on my SAR team swears by his so I snagged one. I used it already to test out and I liked it a lot. I’ll be bringing it on a weekend backpacking trip next month in the UP.”➕

Good for outdoor use

“I really like it, it fits perfectly in the bigger side pouch on my TT raid pack.”➕

“The Grayl is great because it's nearly instant fresh drinkable water.”➕

Effective when used correctly

“Otherwise I’ve had zero issues with mine.”➕

“It’s a fantastic purifier especially for places far away with wacky critters in the water.”➕

Good for maintaining pressure with proper technique

“I still prefer my geopress over any other filter just because I can get 2L of water in less than a minute”➕

“make sure to press straight down on as flat a surface as possible because any pressure at an angle will cause it to jet water back up”➕

Great design aesthetic and functionality

“The design aesthetic is great, feels good looks good. It has a fast pour spout so easy to transfer and drink from.”➕

Effective at filtering water from various sources

“Filtered Water Bottles? GRAYL GeoPress VS LIFESTRAW GO - Are These Actually Good Enough To Take A Scoop Of Water From Anywhere & Gulp It Down?”➕

“I drank a lot of water from nature through the grayl filter, from lakes to rivers - the water still somehow tastes like the source but I kinda like that.”➕

“Hydrablue Versaflow is a backflushable gravity filter. It works great. I also have a Grayl.”➕

Effective at filtering chemicals and metals

“Does Grayl actually filter out what it says it does? I’ve recently been looking into the Grayl geopress filter because it claims that it can filter out chemicals and metals like PFAS, chromium and etc which other water filters like the Sawyer squeeze aren’t able to.”➕

“Greyl has carbon filters and actually filters out poisons. Sawyer does not have any carbon whatsoever but is much lighter and smaller pack size.”➕

Convenient and easy to use

“It's super easy to use and fast to filter.”➕

Effective at removing viruses

“If you purify with a Grayl it will remove the viruses also, so you don't need the extra step of using the chemical tablets.”➕

Convenient for outdoor use

“I use grayl as well and if water is dirty I use a buff mask as an extra filter for filling of the initial cup just cover the opening completely”➕

Good taste of filtered water

“I’ve filtered stream water and lake water. I ended up tasting just like my filtered refrigerator water at home.”➕

Highly recommended by users

“I really do not like the iodine tablets. They are just too weird for me.”➕

“The Grayl is made of good materials, is dead simple to use, and quick.”➕

Effective for various water sources

“None of us have ever gotten sick. It saves weight not worrying about carrying water.”➕

Improves taste of water

“The charcoal filter helps the taste of water from US taps taste much better”➕

Effective at filtering dirty water

“Just want to know before I continue using it.”➕

Where it needs some work!

Areas to watch—feedback on possible improvements.

Becomes harder to press over time

“it is starting to get notability harder to press”➕

Sprays dirty water when pressing

“They just need to add three plastic ridges along the sides to stabilize everything as you push down, it's obnoxious spraying dirty water everywhere”➕

Requires significant strength to operate

“It requires a lot of strength to press down the filtering cylinder. Like, really a lot.”➕

Does not work well with dirty water

“But...it won't work with silty/dirty water. It will clog.”➕

“Slightly silty, muddy/murky or brownish tannin colored water will wreck it.”➕

Limited lifespan of filters

“Water filters are always a good idea. Just know that with Grayl, once you use it, the filters/cartridges only have a 3 year shelf life so buy extras.”➕

Limited filter lifespan

“Water Filters - Grayl Replacement Cartridges for Long Trips? After a number of unpleasant experiences trying to find bottled water, I'm considering just getting a water filter.”➕

“The Grayl may look great but because of that 40 gallon life, it's awful.”➕
