It efficiently removes 99.9999% of bacteria and 99.9% of protozoa, providing safe drinking water quickly and effortlessly.

Despite some concerns about durability and filter effectiveness against certain contaminants, the overall sentiment leans positive, particularly for family and group use. Based on consumer feedback, the Platypus GravityWorks Group Camping Water Filter System is highly recommended for those seeking an efficient and user-friendly water filtration solution for camping and outdoor activities.

What it does well!

Key strengths users can’t stop talking about.

High-capacity water reservoir

“Its great because the reservoir is nice and big so you fill it up and then hang it from a tree and use the water as you need it.”➕

“I have really liked it. It is usually just me and my wife camping/backpacking, and the 4L is a good size for us.”➕

“Fortunately, it hasn’t been stored below freezing, and I’ve just performed the “integrity check” from the manual, which passed.”➕

“Having used both many times, I personally prefer the larger one since it doesn't have to be refilled as often.”➕

Convenient gravity-fed system

“Gravity works platypus”➕

“I love my gravityworks. Doesn’t do viruses, but where I am that’s not an issue.”➕

“A friend brought one of the Platypus gravity systems on our last hike and it worked great.”➕

Effective filtration for clean water

“I like that it filters faster and would work better with soft flasks to just drink out of that easily while on the go.”➕

“Probably. The brown you're seeing are tannins (chemicals from root systems of the plants in and around the lake) and aren't normally filtered out.”➕

“The colour really isn't a reliable indication of whether the filter is working or not, I use one in Scotland and the tannins never get filtered out.”➕

Great flow rate

“Flow is great. It is convenient to drink straight out of, similar to the Squeeze or Katadyn.”➕

“Flow rate is awesome.”➕

Better flow rate than competitors

“Seems to have a better flow rate than my Sawyer filter.”➕

“It has better flow rate than a Sawyer squeeze, but worse than a Befree *when new*.”➕

Thoughtfully designed product

“It's just a better designed product than the Sawyer at a lower price point”➕

Convenient flip top cap design

“The filter seems very promising and I'm excited to test it in the field.”➕

“The flow seems really nice.”➕

Effective filtration for bacteria and protozoa

“Platypus Water filter and tablets? Was looking at a Platypus gravity works water filter and was wondering if it's a good idea to still use water tablets with it?”➕

High capacity for group use

“It's hard for me to think of why the 2 L would be better.”➕

“I have the 4L version and it's hard to see the benefit for the 2L version for 1oz.”➕

Includes useful adapters for direct filtering

“Not taking out your bladder is great.”➕

“2L or 4L it's a great product.”➕

High water capacity reduces trips

“Bought this last spring and love it so far!”➕

Effortless to use

“I use a Platypus GravityWorks filter. It is almost effortless to use, it is a pretty small package, and my favorite thing is that I can use the dirty water bag to bring water with me that I want to filter later.”➕

Works wonderfully for camping

“I have the 4L Platypus and it works wonderfully when you get to camp and have a bit of time to get settled while it filters.”➕

Where it needs some work!

Areas to watch—feedback on possible improvements.

Durability concerns with the Platypus product

“My buddy got the Platypus and within a couple of years the top bag wouldn't close properly.”➕

Concerns about filter effectiveness against certain contaminants

“Just to note that the faster flow rate is by having bigger holes than the Sawyer, and hence less effective filtering.”➕

“Without seeing the complete setup it's hard to tell.”➕

Inconsistent filter lifespan

“I never pre-filtered water with sediment and did very little maintenance on them while in use.”➕

“I can't imagine this is typical, but the point is don't expect a slow filter out of the box to get better.”➕

Flow rate may be slower than competitors

“Flow was not noticeably faster than the Sawyer--in fact it seemed maybe a little slower.”➕

Concerns about backflushing capability

“The main selling point of this filter will be if it can be backflushed as good as the Sawyer Squeeze.”➕

Core Power Plays

The specs and strengths that make it shine.

Impact of debris on filter performance

“People filter water from far worse sources than that with no issue.”➕

User experiences with filter maintenance

“The BeFree will give the appearance of being „blocked“ when it’s used from dry.”➕

Comparison of 2L and 4L versions

“I can't think of any reason to get the 2 liter. It's worth the ounce.”➕

Hidden Hero Hacks

Unexpected tricks and side‑door uses you’ll love.

Experiences filtering from questionable sources

“I've used worse for my squeeze and been fine”➕

“Yes totally. I’ve had to do worse then the one in the pic.”➕

Advice on cycling water through the filter

“My dad had one like that and I think he had to cycle water a few times just to get the filter working.”➕

Discussion about using other systems

“I gravity feed it to my water bottle or a Platypus bag depending on where I'm at.”➕

“This filter fits the Cnoc bladder for the sawyer I believe.”➕

Discussion about using water tablets as backup

“While some hikers carry tablets as a backup, most people don’t use both.”➕

Buyer’s Cheat Sheet

What to check before you click ‘Add to Cart.’

Advice on using compatible bags for filling

“Get a bag to attach so you can squeeze fill your bottle or hang up as a gravity filter.”➕

Discussion about filter lifespan and maintenance

“A new filter every year? Aren't they good for 10,000 filters? Just run some bleach or vinegar through it to save some money.”➕

“Depending on where the water was sourced, it still might not be safe to drink. Boiling it will kill microbes but does not remove heavy metals and other harmful additives.”➕

Preference for cleaner water sources

“I definitely try to get from the cleanest source - if it’s a pond/lake is there any stream running to or from it - I’d choose a small tricking stream over stagnant questionable water but that’s just preference.”➕

Comparison to other water filters

“the flow rate is great out of the box but drops fairly quickly.”➕

“Once the BeFree is clogged and you can't swish-fix it, it's trash and you'll go thirsty or drink unfiltered water; choose your demise.”➕

Comparison to other filtration setups

“Done. It's the same thing. Now save yourselves some money and go custom.”➕

Consideration of alternatives like Sawyer

“I'm looking into either the Platypus gravity or the sawyer squeeze.”➕

“Using the squeeze system is excellent for 1 person and good for 2, but I wouldn't want to use it for any more than 2 people, that would be a lot of work.”➕

“Honestly, you'd really probably be fine with just the Mini for most purposes unless you were filtering a large volume of really cruddy water, and then you wouldn't need the separate adapters.”➕

“Personally I use the Mini and it works great.”➕

Discussion about compatibility with other filters

“Gives me the best of both worlds, since reviews seemed to favor the Sawyer filter but I liked the Platypus bags.”➕

Comparison of gravity filters and personal preferences

“Really the same tech as the MSR and platypus gravity filters.”➕

“Plus it's just nice to be able to hang up a bag of water and have filtered water whenever you need it.”➕

Cautionary Callouts

Know the pitfalls before they catch you off guard.

Preference for other brands over Platypus

“Sawyer is great. The filters are compact and filter lots of water”➕

“Sawyer Squeeze (the bigger one) is only like an oz heavier and it has 3 times the flow. I'm an avid backpacker and I have both.”➕

“Generally using for only 1-2 people either backpacking or bike packing. Seems like these 3 companies make similar type 'squeeze' type filters which II haven't used before but figure this is the new style.”➕

“I found the msr finicky and slow. Bought a katadyn and really like it”➕

Concerns about virus removal capability

“Thanks OP for including the boiling part. I've seen several videos showing "hacks" to filer water that ignore it, making people believe that it is already drinkable.”➕

Concerns about filter integrity and proper storage

“I think it’s more likely to be okay than it is to be degraded so it won’t keep you safe. But I really wouldn’t take a risk with something so important.”➕

“Needed someone to tell me this, thank you! I’ll replace it and this time I’ll store it properly.”➕

“You could do nothing and hope for the best, or replace it and be confident that your drinking water is safe.”➕

Concerns about heavy metals in water

“If you would boil the water but catch the water VAPOUR Would this be 'pure' or would those particles still be attached to the water molecules?”➕
