Recent Bottle/Inline Water Filter Reviews
It does filter water, but the whole design is poorly thought out and low functioning. It is the least practical item of travel gear I own. The design is so unbelievably poor I’m amazed they got it through R&D. It leaks constantly, it’s bulky and heavy, the strap isn’t even designed to make it easy to carry, the whole thing is so poorly thought out it beggars belief. Does the filter work? Yes, it filters out bacteria and viruses. I used it for 10 days on Jordan tap water and had no issues… Full review
Aquamira WaterBasics RED Line Filter Bottle
The Aquamira Red Line filter blocks 99% of bacteria and microbes, plus 99% of viruses. Handy for dipping in the stream on the trail and drinking immediately Aquamira Red Filter Bight that Valve!* Well—the bite valve came off the filter and I had to futz with it to put it back on the filter. May be a hazard of bite valves in general. Was told about Aquamira filter systems by a veteran mountaineer friend. He found it the most efficient way of staying supplied with water in the backcountry. Last… Full review
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
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
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
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
