Questionable reliability

I purchased a 4.0L Gravityworks filter back in 2022 and was initially exceptionally pleased with it. Used it the summer of 2022 and was quite happy with the results. I followed the instructions to a “tee” at the end of the season when putting away for long term storage. When I pulled it out May/2023 I didn’t test it beforehand (I should have, that’s my fault). But I hiked up into the bush and when I got to the camping area I went to get my water. I filled the dirty reservoir, and made all the necessary attachments to the clean bag. Zero flow. None. The water wasn’t penetrating the filter at all. I was mortified at the catastrophic gear failure. I always backflushed, had used the filter only sparingly and, as mentioned, followed all instructions for long term storage. So I was forced to boil water for my drinking and cooking needs. Not an ideal situation, particularly since I’d only brought so much fuel. I was able to boil enough water for my needs for two nights in the bush but it was a labour intensive undertaking that should have been avoided but for a clogged filter. After that trip I purchased a replacement filter and took it on a six day solo hike of the North Coast Trail. On night one it worked like a charm. Super fast flow and I had eight liters of water in about 10 minutes. During the trip I always made sure to back flush after every other filter. Nevertheless by my last day the filtering process took considerably longer than that first day. Eight liters was taking me about 30-45 minutes to filter. I’ve just stored the filter away for the winter (per instructions ) and will test it again before my first hike in spring 2024. I want to like this filter, I really do. When it works it works well, it’s lightweight, simple to use and takes up remarkably little space in the backpack. But my experience to date has made me nervous to rely on it, particularly during multi day through treks. As such I believe my experience to date warrants a three star rating.

Looks like it could be a great filter, but mine doesn't work (details below)

I picked this up a couple months ago thinking it would be great for canoe camping. Unfortunately there must be something wrong with the unit I received. I can barely get a trickle of flow through. I tried all the backflushing tricks that are suggested in case the issue was air bubbles trapped in the filter, but only got a trickle of flow on the backflush too. I also did the filter integrity test but I wasn't able to see bubbles coming out so I know that isn't the problem. And of course it's brand new so it can't be from sediment build up. And it's been on a shelf in my closet so no drops/freezing. Finally after fiddling with it for an hour I took the end caps off the filter to see if there was visible damage to the hollow fibers. There isn't (as far as I can tell) however there is a film (almost like glue) covering the end with all the little hollow fiber tubes. I don't know if that film/glue is supposed to be there, but in my case it seems to be blocking all water flow through the filter. Barely any water makes it through that film. Anyways, all that is to say that my filter doesn't work. And unfortunately I lost my receipt so return/warranty isn't an option. Now I have to decide if I by a replacement, or just go to another brand. I definitely don't want this to happen again given how much the filters cost.

AK Moose Hunt

I used the gravity works 6.0L for 2 weeks on a moose hunt in Alaska. It filtered water for myself and two clients for everything. We were using water from a pretty nasty lake. Water always came out clear and clean and actually pretty quick too.

Appalachian Trail 2017

I used my 3 stage filter, from Georgia to Maine…5 months 3 days. It never failed me. After the trip, I asked my nephew what his favorite piece of equipment was on our trip…he laughed and said, “YOUR Platypus” he only had the Soyer squeeze. I’ve continue to use it for 6 years.….new filter of course.

Great system, fast filtration. Highly recommend. Great to use when you have a stream or pool to fill quickly. Much faster than a hand pump for getting a large amount of water. No issues.

Lightweight, super fast for group of 2 or more.

I bought this for a group backpacking hunt and was really impressed with it! The bags have a wide enough lid that getting water from a stream or river is super fast. Still water takes slightly longer. This filters water super quick as well, I never timed how long it took but approximately a minute for the 6l version. This will be my go to water filtration system for all my backpacking hunts unless weight saving is crucial and only filtering for myself then I will stick to my MSR thru-link.
