0.01μm Ultrafiltration Technology
Filtered Drinking Water from Natural Sources
At the heart of the PureDropy Gravity Water Filter is a multi-layer 0.01-micron hollow-fibre membrane. As water passes through, the membrane traps sediment, silt, micro-particles and microplastics, and is designed to remove 99.9999% of bacteria and protozoa – all without chemicals, tablets or any aftertaste.
Use it to filter water from:
- Mountain streams
- Rivers
- Lakes
- Natural springs on the trail
For water you suspect may contain chemical contamination or viruses, pair it with purification tablets for complete peace of mind.

Enough Water for the Whole Camp
Constant trips back to the stream soon get tiresome. The PureDropy Gravity Water Filter holds 10 litres at a time, giving you a plentiful supply for long days outdoors and family trips without constantly refilling.
Perfect for:
- Drinking water for several hikers

- Making hot drinks
- Washing up and personal hygiene

Hands-Free Gravity Filtration
No Pumping, No Batteries, No Effort
Fill the bag, attach the tube, hang it from a branch or hook and let gravity take care of the rest. With no electricity or batteries required, the PureDropy Gravity Water Filter keeps working when you're far from a plug socket – and there are no motors or pump handles to fail.
While it filters, you can:
- Pitch your tent
- Gather firewood
- Prepare your meal
- Rest after a long hike
Fast, Steady Flow Rate
Up to 1 Litre Every 2–3 Minutes
The PureDropy Gravity Water Filter delivers up to 1 litre of filtered water every 2 to 3 minutes. The higher you hang it, the better gravity works for you – actual flow depends on the hanging height and how clear the source water is.

Easy Backwash Cleaning
Keep the Flow Rate Strong
When the flow starts to slow, use the backwash syringe with clean water to flush trapped sediment from the membrane and restore maximum flow. This quick routine helps extend the life of your filter across many trips.
