The Grayl UL is heavier and more expensive than in-line filters like the Sawyer Mini or Squeeze. But when we consider that it doesn’t require a container and also filters out viruses and chemicals/odors, it shows some advantages. It’s an all-in-one solution, good for outdoor use, but perhaps even more for emergencies: for those qualities I keep one new in my bug-out-bag. I see the Grayl UL as more of an all-in-one solution to water treatment and storage than a simple filtration system. I can… Full review
For day hikers and overnight adventurers, fill this beauty up with water at the start of your hike and when you find a water source, drink what you have and refill the Grayl. Original reviews talked about how difficult it is to press (filter) the water, think of a french press coffee maker, not hard at all and I am quite small. I love this simple, perfect system This is an easy to use, effective, fast source of filtered water. The capacity of fresh water that is also stored directly in the french-press… Full review
The easiest and likely fastest filter of its caliber on the market. Takes absolutely disgusting water and turns it into purified clean, tasty water. Wife and I use this on camping trips. So super simple and fast, very tough as far as the hardware pieces go. We like to backcountry hike and camp. The $80-$90 cost for this filter, with regard to the ease and safeness of the water you get, is worth each and every penny. Full review
Excellent backpacking water filter, super versatile and convenient, and definitely my favorite so far. Has a significantly better flow rate compared to the Sawyer Mini. It can be adapted to several different systems. It's threaded so you can screw it directly onto a bottle, or onto a bladder to use as a squeeze through filter system or hung for gravity filter setup, and you can put a hose on it for in-line filtering. I prefer to use mine screwed directly onto a dirty water bladder (I've found CNOC… Full review

Consistency in filtering is an issue. Weight is heavy and constant cleaning of filter, along with difficulty in usage, make this a "miss" for filter choice. I'm confident of the effectiveness in filtering—I have drank some poor quality water and never got sick. I have had lots of problems though. It sometimes clogs and is very difficult to pump. It requires scrubbing of the ceramic filter very often, meaning you have to take apart to clean, lose pressure, and risk having it not work properly. Full review
I was gifted a Grayl by someone who knows that I have occasionally taken risks with drinking stream water on hiking trips, so far so good but it drove them crazy. This filter is highly effective, durable, no parts to hunt around my pack for, will suffice for day hikes and longer hikes and acts like a great water bottle. I love it! Full review
I have been testing the Grayl GeoPress Purifier, a new, large capacity water filtration bottle, while canoeing, canoe camping, and day hiking this summer and fall. For the past three years, I have used a Grayl Ultralight Water Filter bottle, to provide clean and safe water for me and my dogs while canoeing and camping. I reviewed that bottle here on Trailspace on 10/14/18, and since then have continued to carry that bottle in my canoe bag, and occasionally, in my backpack side pockets. The new GeoPress… Full review
The Sawyer Micro Squeeze is a very lightweight, compact, and versatile water filtration system with a long lifespan that will help keep you safely hydrated on the trail. You can drink directly from the water source with the included straw or filter water from the included bladder using the squeeze method or from disposable water or soda bottles using the gravity method. Once filtered it's ready to drink or store in the vessel of your choice, and you can even direct line to hydration packs. Sawyer… Full review
