CLEAN WATER. ANY SOURCE. ANYWHERE.

SCENARIO 01
HIKING & TREKKING

Streams, rivers, and lake water carry bacteria, sediment, and chemical runoff. The Source filters at the point of drinking — attach to your water bottle, draw through the straw, and the 2-stage membrane catches what the water source leaves in. No boiling required, no tablets that affect taste.

SCENARIO 02
CAMPING

Connect The Source to a water bag and filter your entire camp supply without pumping by hand. The pressurization function accelerates flow when the bag pressure drops — consistent filtration from a full bag to the last litre. Pack it in, leave the heavy filter system at home.

SCENARIO 03
INTERNATIONAL TRAVEL

Tap water quality varies wildly outside familiar territory. The Source removes chlorine, bacteria, and sediment from hotel tap water, airport fountains, and unknown sources. Eliminates the cost and waste of buying bottled water every day. At 18.5cm, it fits in a jacket pocket or day bag.

SCENARIO 04
EMERGENCY PREPAREDNESS

Infrastructure failures make tap water unsafe. The Source provides independent water purification when supply systems are compromised — no electricity, no chemicals, no moving parts to break. One unit handles a family's drinking water from any available source until normal supply is restored.

SCENARIO 05
FISHING & HUNTING

Extended time in the field means carrying enough water or finding it on location. The Source is light enough to carry on every trip as a backup — attach to any bottle you find or fill, and the filter handles the safety question. No separate treatment system to remember.

SCENARIO 06
EVERYDAY HOME USE

Tap water in many cities carries detectable chlorine, rust from aging pipes, and sediment. The Source removes all three at the point of use — connect to a bottle and filter straight from the tap. Food grade ABS makes it safe for daily use by children, pregnant women, and the elderly.

WHAT MAKES THE SOURCE DIFFERENT

01
2-STAGE ULTRAFILTRATION MEMBRANE

Most basic filter straws use a single carbon layer that removes taste and odour but leaves bacteria. The Source uses a two-stage ultrafiltration membrane system — the first stage removes suspended particles, sediment, and rust; the second stage removes bacteria and microscopic contaminants at the membrane level. The result is water that is clean at the microbial level, not just improved in taste.

02
PRESSURIZATION FUNCTION — FASTER FLOW WHEN IT COUNTS

Standard filter straws rely entirely on suction to pull water through the membrane. As the filter loads or the water source is cold, flow slows to the point where drinking becomes effort. The Source adds an active pressurization function — compress the body to push water through the membrane rather than pulling it. In field conditions where hydration speed matters, this is the difference between a functional tool and a frustrating one.

03
UNIVERSAL CONNECTION — BOTTLE AND WATER BAG

The bottom thread connects to standard water bottle mouths and water bag valves — attach and drink directly without removing the filter. This means The Source works as a straw filter, a bottle-top filter, or an inline water bag filter depending on how it's configured. Three use modes from one piece of kit, none requiring adapters or proprietary fittings.

04
CLEANABLE FILTER ELEMENT — NO SINGLE-USE WASTE

The filter element is removable and designed to be backflushed — run clean water through in reverse to clear accumulated sediment and bacteria from the membrane. This prevents clogging and eliminates the bacterial growth that forms in filters that can't be cleaned. In extended field use, the ability to maintain the filter on-site is the difference between a tool that keeps working and one that becomes useless after one day.

WHAT PEOPLE SAY

★★★★★
“Used this on a 5-day trail in the Rockies. Drank straight from mountain streams the whole trip — no tablets, no boiling, no stomach issues. The pressurization is a real feature, not gimmick. When suction slowed in cold water, one compress pushed it right through.”
— Marcus T., Colorado

★★★★★
“Bought three — one for each family member's go-bag. The fact that it connects to a water bag means we can filter and store, not just sip. Cleaned the filter element twice now, still flowing well. It's a serious piece of kit for the price.”
— Rachel M., Texas
✓ VERIFIED BUYER
★★★★★
“Took it to Southeast Asia for two months. Filtered tap water every day in countries where I'd normally buy bottles. Zero illness, massive cost saving, and no plastic waste. The food grade material matters — my kid uses one too.”

FREQUENTLY ASKED

Does it actually remove bacteria?

Yes. The 2-stage ultrafiltration membrane is rated to remove bacteria at the membrane level — this is different from activated carbon filters that only improve taste and odour. The ultrafiltration membrane physically blocks bacteria and microorganisms from passing through. It does not remove dissolved chemicals like pesticides or heavy metals beyond chlorine — for those, a dedicated chemical treatment is required alongside the filter.

How does the pressurization work?

The body of The Source is compressible. When suction alone is insufficient to pull water through the membrane — typically in cold water or as the filter element loads — you can squeeze the body to push water through instead. This is the same principle as a squeeze filter, combined with the option to use standard suction when it's sufficient. No pump mechanism, no moving parts to break.

How do I clean the filter element?

Remove the filter element from the body and backflush with clean water — run clean water through the outlet end (the end you drink from) in reverse to push accumulated sediment and bacteria back out through the inlet. Do this after every use in heavily contaminated water, or when flow rate decreases noticeably. Allow to air dry completely before storage to prevent mould growth inside the membrane.

What bottles and bags does it connect to?

The bottom thread is designed to fit standard water bottle mouths and common water bag valves. Most standard outdoor water bottles (wide-mouth and standard-mouth) are compatible. Check your specific bottle or bag thread type before assuming compatibility — if in doubt, The Source also functions as a standalone straw filter without any attachment.

Is it safe for children?

Yes. The material is food grade ABS — the same grade used in food containers and children's products. The filter removes bacteria, chlorine, rust, and sediment, making filtered water safer for vulnerable users including children, pregnant women, and the elderly. It is not a substitute for professional medical advice in areas with known waterborne disease outbreaks.
