Trade-offs
- Heavier than squeeze or bottle filters
- Needs a hang point — awkward on exposed terrain
I carried Katadyn BeFree on Alta Via 1 for solo hut sipping. GravityWorks is what I recommend for camping treks and base camps where filtering litres for cooking beats squeezing at every meal.
My experience on the trail
I have not carried Platypus GravityWorks on a published HikingWithLee trek — my hut-route filter was the Katadyn BeFree bottle for on-the-move drinking. I have set up GravityWorks kits on camping shakedowns and recommend them in guides for group wild camps and fixed base camps where water volume matters more than grams in a daypack.
The workflow is different from squeeze filters: hang the dirty reservoir, walk away, and return to litres of clean water in the Platy bottle. While you pitch tent, sort food, or wring out socks, the filter works without hand fatigue — that is the entire value proposition for two-person camping kitchens.
Who it's for
Small groups, base camps, family camping, and trekking itineraries with fixed wild camps where you filter multiple litres at once for cooking, bottles, and hydration bladders. Strong fit for two hikers sharing a campsite who would otherwise take turns squeezing Sawyer bags.
Overkill for solo hut days where a BeFree or Sawyer handles occasional refills between rifugi. Also impractical on exposed cols and lunch stops without trees or hang points.
How it compares
Sawyer wins on weight and lunch-stop speed for solo hikers; GravityWorks wins when filtering litres for two people at camp without hand squeezing.

BeFree is what I carried on Alta Via 1 — integrated drinking on the move; GravityWorks wins for camp kitchen volume and hands-free workflow.

Read full reviewTrade-offs
- Heavier and bulkier than squeeze or bottle filters — wrong tool for fast hut-to-hut days with rifugio taps
- Requires setup time and flat-ish camp — not instant water at a stream crossing
- Group-oriented value — solo ultralighters pay weight penalty without sharing labour savings
- Hang-point dependency — plan campsites with trees or carry a pole rigging system

Bottom line
Platypus GravityWorks 2L is the camp filter I recommend when hands-free litres matter — pair it with personal squeeze bottles for trail days, hang it at camp, and stop squeezing every cooking potful by headtorch.

Camp workflow
Hang the dirty bag from a tree branch, trekking pole tripod, or rock hook at camp arrival. Connect hoses to the cartridge, open the clamp, and let gravity do the work into the clean Platy bottle. Fill cook pots, water bottles, and bladders in one session while you set up shelter.
Keep dirty and clean reservoirs clearly separated — colour coding helps tired brains. Backflush the cartridge when flow slows, same as squeeze filters after silty sources.
Kit and capacity
- Complete kit
- Dirty reservoir, clean reservoir, hollow-fibre filter cartridge, hoses, and shutoff clamp — verify 2 L vs 4 L kit size for your group.
- Flow rate
- Roughly 1.5 litres per minute when clean — fills cook pots while you unpack.
- Filter life
- Cartridge rated for thousands of litres with backflushing — group trips amortise cost quickly.
- Packed weight
- Heavier than any squeeze system — justify only when camp volume filtering is daily workflow.
Trail limitations
Needs a hang point and reasonable head height — less practical on exposed cols, alpine bivouacs without vegetation, or lunch stops on open ridge. This is camp gear, not daypack sip gear.
Bulkier packed size than Sawyer or BeFree — split components between packs on duo trips or accept the weight penalty on camping-focused itineraries.
Freezing damages hollow fibre — store in tent or sleeping bag in cold camps, same rule as every squeeze filter.
