Membrane Solutions Orange Personal Water Filter Straw with Protect

In this review the Membrane Solutions Orange Personal Water Filter Straw is evaluated as a compact backup purifier for hikers and travelers who need reliable drinking water without heavy gear. The single biggest reason to buy is its combination of a true 0.1 micron hollow fiber membrane and a protective EVA carry case that keeps the straw ready for emergency use; together they deliver high filtration performance in an ultralight package that fits a pocket or pack.

Key Features

• 0.1 micron hollow fiber membrane: Provides high-efficiency removal of bacteria like E. coli, offering peace of mind when drawing from streams or lakes.
• Five-stage filtration: The combination of coarse screen, PP cotton, activated carbon and hollow fibers reduces sediment, bad odor and improves taste.
• Portable size: At about 7.0 in long and 1.3 in diameter the straw fits in a pocket or bag for fast access during hikes or emergencies.
• Long service life: Rated for up to 5,000 liters (approximately 1,320 gallons), making it a durable choice for repeated trips or long-term emergency kits.
• Protective EVA case: The hard, shockproof, dustproof carry case with zipper, mesh pocket and carabiner keeps the straw clean and easy to attach to a pack.
• High flow rate: With an approximate flow around 500 ml per minute it provides drinkable quantities quickly without laborious pumping.

Who It's For

The filter straw is aimed at backpackers, campers, hunters and travelers who want ultralight, reliable emergency water purification that can be used directly at rivers, ponds and lakes. It suits anyone who values compact gear that can be stowed in a daypack, survival kit or glovebox and deployed instantly when clean water is needed.

Those who should look elsewhere include groups that need to treat very large volumes rapidly for multiple people at once or users who want chemical disinfection for viruses; this straw is best as personal, point-of-use filtration rather than a household or multi-person station.

Pros & Cons
