Convert your GravityWorks into a Basecamp Spigot and Hydration Bag Refilling Station (see image)

A very simple and efficient way to create a basecamp spigot and hydration bag refilling station (see image for details). Just add a few inexpensive hydration tube quick-connect adapters to the clean filter line and to your backpack’s hydration bag line and you’re in good shape even for trekking/expeditions. But I would not bring this setup to a place where I did not know moderately clean water existed unless you a) want to clog your hallow-fiber filter and b) have a way of accessing very low or no-flow water sources (ultra-thin creeks or pooled water down below boulders/crags). For those applications, a hose and a pump are more reliable (I use Katadyn). But I always bring the GravityWorks when I know there’s a reasonable water source.

BEST Water filter! Period.

Incredibly handy! Before buying this I did an exhaustive amount of research on water filters. What sold me on this is the fact that you can get a lot of water in one shot, it filters FAST, and most importantly… NO PUMPING! If you’re backpacking this is a no brainer. Water weighs 8.3lb per gallon and an adult needs about a gallon a day, so bringing water on a multi-day trip is not an option. This weighs less than a pound at 13.6oz! This can also save you money in the long run. The filter lasts for 1500 liters or 396 Gallons, If you’re buying gallons of water from the store that’ll cost you $350-$400. Even if you’re filling from the tap this will save space and save you from having to lug water around.

I can’t believe this wasn’t developed years ago. I’ve been camping for decades, some trips days, others weeks long. I have used (gone through) many water filtration tools (including ultraviolet treatment and, of course, tablets). While most of these devices work adequately and last (if treated carefully), the GravityWorks filter is BY FAR, the easiest most foolproof one I’ve used. While it looks big in the images, it rolls up to about the size of most standard filters (probably a bit smaller). I think it makes more sense to get the 4 liter as it really is not significantly more to carry and allows for fewer trips to your water source and more clean water at hand. This is my 1st review of any camping product, figuring the companies can do their own advertising. BUT I gues I’ve never liked a product this much. Have fun.

I used this as my primary water filter on a 4-day kayaking trip. (It was on a well-traveled river, so I also used chlorine tablets overnight, just to be safe.) It worked great! My only complaint is that the cleaning process is somewhat tedious, because the “Clean” bag doesn’t have an accessible interior. Dirt that gets in there is tough to get out, and the drying the inside of the bag takes forever.

Great system for groups!

This filter system is perfect for us. We tend to take groups of 4-10 hiking, canoeing, backpacking, etc for days at a time and needed a reliable way to filter a lot of water. Obviously, the pump filters just aren’t ideal for filtering water for large groups of people. We’re in Florida and are usually pretty close to surface water and prefer to filter as much and as often as we can, instead of filtering ‘just what we need’, to insure that everyone stays hydrated. I never want clean water to be a chore because in my experience, it leads to dehydration.

As a hiker who has done the AT, the Long trail and 200 miles of the Colorado trail, I finally found a system that I really like. previously I used a Katadyn hiker pro and always grumbled at the end of a days hike when I had to PUMP that device to fill up my platypus bags. After a days hiking I am usually tired and energy is lacking. I should add that I am now 77 so maybe that explains some of it (so you young “lions” can go on using your PUMP water filters they are great too). With this unit you simply fill the top bag and hang it up. Within a very short time you have clean, filtered water. One CAVEAT: You have to carry a plastic cup to use to fill the top bag because water sources are not always easily accessible. A plastic cup only weights a couple of ounces so for me, anyway, that is not a problem. One last note. With any water filter that uses a cartridge (this one & the Katadyn are examples) be aware that in Colorado and other mountainous regions there may be SILT in the water that will clog your cartridge making the filter unusable. This happened to me on the PLATTE river. I should have found a quiet “pool” and not filled in the swift current. just an FYI.

5 Stars PLUS!

Just finished a 4 day backpacking trip on the Ouachita Trail in Arkansas and this system is AWESOME! We were sub zero (C) for over 2 days and this worked like a champ! Few caveats. 1. Make sure you do at least a 4 second back flush, it really helps. I usually backflushed 30 seconds or so 2. Also remember to keep your eye on the $100 plastic cap that seals the CLEAN water bag once you are through filtering. It’s very small and easy to lose. 3. The clean water comes into the CLEAN bag at a 90 degree joint. That can “kink” on you. Keep your eye on that. 4. In very cold weather make sure to completely dry out the gray snap lock at the outlet of the DIRTY bag. It can freeze up on you. Kept the filter under the shell next to my body and it filtered water in single degree temps. It’s fast and serves up a ton of water in no time. Yeah it’s a little pricey, but well worth it. I would give it six stars if I could. Platypus has hit it out of the ball park with this.

This thing is AMAZING and QUICK!

This is AWESOME for groups. We do a family backpacking trip to a lake in Yosemite every year or two – and we can have more than 15 people there at a time. This means we have had to take turns pumping and sharing just 2 or 3 filters and it takes FOREVER. This sweet setup takes hardly any time… just scoop up some water and filter away. I think this would be helpful even with 2 people since it’s super quick and then you’d be able to fill your water bottles and have water for cooking. It’s also nice because you can store water in the clean water bag and refill as needed.
