Katadyn BeFree 0.6L

Works well when it works, but seems to be unreliable. My filter malfunctioned after just 10 days of use in the field, even though I followed the instructions in the manual. I purchased a BeFree filter in March 2018 and used it for a total of 10 days on hiking and kayaking trips here in Australia before the pandemic started. It worked well in that time with a good rate of flow and I liked how simple and compact it was, enabling me to easily filter water even when inside my tent. Two weeks ago, on… Full review

Grayl GeoPress

The GeoPress is fast and clean, never leaks, and does a better job of providing super clear water than my Lifestraw did. You do have to use a fair amount of pressure to push it down, but the excellent results are worth it. Oh, and it is also easier to clean with a quick rinse. Use this just like a water bottle—plunge and you are good to go. I have filtered lots of river and pond water with excellent results. No muss, no fuss.   If you are just filtering municipal water, get a cheaper, lighter… Full review

Grayl Ultralight

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

Grayl GeoPress

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

Grayl GeoPress

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

HydroBlu Versa Flow

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

Grayl GeoPress

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

Grayl GeoPress

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
