Membrane Solutions Water Filter Straw is a personal water filtration straw certified to NSF/ANSI 42, 372 and 401 to tackle chlorine, particles and emerging contaminants. Lightweight and compact, suitable for hikers, travellers and emergency kits who need quick access to safer drinking water. Does the cleaning system and long lifespan make it a sensible choice for extended trips?
⚡ At a Glance
- • Filtration Performance: 0.1 micron hollow fibre membrane with a maintained flow rate of around 500 ml/min
- • Best for: Backpackers, international travellers and emergency kits needing reliable on-the-go filtration
- • Not ideal for: Users who need desalination or reduction of dissolved solids (TDS)
Certified to NSF/ANSI 42, 372 and 401 with a 5-stage filtration system. Removable ends and a backwash function extend usable life to about 5,000 litres.
Safer drinking water – with a 5-stage filtration system
Activated carbon plus a hollow fibre ultrafiltration membrane form the core of the five-stage system, combining adsorption of chemicals with mechanical removal of particulates. The hollow fibre element traps microorganisms while carbon improves taste and reduces chlorine.
High microbiological reduction and improved taste let users draw water from suspect sources with greater confidence. The system specifically targets particles and chlorine while leaving essential minerals intact.
Quick hydration on the move – thanks to a 0.1 micron pore size and steady flow
A 0.1 micron pore size provides high filtering accuracy while design optimisation maintains a flow rate of approximately 500 ml per minute. Smaller pores remove finer particles without severely restricting throughput.
Fast, steady flow makes drinking straight from streams, pouches or bottles practical during hiking or travel. Users can hydrate without long delays between sips or extended pumping.
Durable and reusable – with backwash cleaning and removable ends
Both ends are removable to allow backwash cleaning, which clears trapped debris from the hollow fibre membrane. Regular backwashing significantly extends operational life to roughly 1,320 gallons (5,000 litres).
Long lifespan reduces waste and the need for frequent replacements, making the filter economical for repeated trips. Cleaning by backwash keeps performance stable over many uses.

❓ Frequently Asked Questions
Q: Can the filter remove bacteria and other pathogens?
A: Yes. The hollow fibre ultrafiltration membrane with a 0.1 micron pore size is rated to remove microbial contaminants, with a stated 99.9999% reduction of E.coli.
Q: Will the filter reduce dissolved solids (TDS) or desalinate seawater?
A: No. The filter cannot lower TDS value and does not remove dissolved salts; essential mineral balance remains untouched.
Q: How is the filter cleaned and how long does it last?
A: Both ends are removable for backwash cleaning, which extends usable life to about 1,320 gallons (5,000 litres). Regular cleaning maintains flow and performance.
🏆 Our Verdict
Ideal for hikers, travellers and households preparing emergency kits who need fast, reliable removal of particles and certain contaminants. NSF/ANSI certification combined with a 0.1 micron hollow fibre membrane and a five-stage system is the defining strength for microbiological safety and taste improvement. While upfront choice depends on individual needs, long lifespan and cleanability deliver strong long-term value without repeated disposable waste.
