Amazing water filter straws – great for hiking and emergency kits
I originally bought these water filter straws for my emergency kit, but I had the chance to try them during a recent hiking trip and I loved them. We tested them with lake water and it worked perfectly—the water came out clean with no weird taste. I was really impressed with how well they work and how easy they are to carry. Now I feel even more confident keeping them as a key part of my emergency supplies.

Great idea
I have read about these straws and hope to never have to use it. I bought it for an emergency situation.
Scott R. Gerber –
Good price and well built
I bought these because of a recommendation. I have not used them as of yet. They appear to be made well and come with a good rating from other customers. They are portable with a fair price point and can last over extended use.
Amazon Customer –
A necessity for hiking, camping, emergencies and a “Go-Bag”.
Have not actually used. Ratings indicate a good product. We have them on-hand in case of need.
Tailore –
Great for the price!
We ordered these to go into our”Go Bag” as my husband says. Have not used them, but was heavily recommended and happy to finally have!

Quality
These are one of the best quality emergency water filters on the market. They work great. I’m giving some as gifts for Christmas to some of my hikers friends & some for auto emergency kits.

Ich habe den Membrane Solutions Wasserfilter für eine mehrtägige Trekkingtour ausprobiert – und bin absolut überzeugt! Hier meine Eindrücke:✅ Top Leistung & SicherheitMit einer Filtergenauigkeit von 0,1 Mikron entfernt der Filter laut Hersteller 99,9999 % E. coli und andere schädliche Bakterien. Ich habe damit Fluss- und Seewasser gefiltert – der Geschmack war neutral, das Wasser klar, und ich hatte keinerlei Magenprobleme. Ein gutes Gefühl, sich auf diesen Filter verlassen zu können!✅ Extrem langlebigMit einer Kapazität von bis zu 5000 Litern ist dieser Filter sehr nachhaltig – ideal für Vielnutzer, längere Touren oder Notfallsets. Kein Vergleich zu Einweg-Wasserfiltern!✅ Leicht & kompaktDer Filter ist sehr leicht und handlich, passt in jeden Rucksack. Perfekt für Camping, Wandern, Bushcraft oder auch als Notfalllösung zu Hause. Trotz seiner kompakten Größe fühlt er sich robust und wertig an.✅ Einfach in der HandhabungOb direkt als Strohhalm, am mitgelieferten Schlauch, mit einer Wasserflasche oder einer Trinkblase – der Filter ist vielseitig einsetzbar. Die Anleitung ist verständlich, die Anwendung intuitiv.✅ BPA-frei & umweltfreundlichSchön zu wissen: Das Material ist BPA-frei – ein weiterer Pluspunkt in Sachen Gesundheit und Umwelt.⸻❗ Kleiner HinweisBei sehr trübem Wasser dauert das Filtern etwas länger – hier lohnt sich eine Vorfilterung oder das Absetzenlassen des Wassers. Das ist aber bei dieser Filtertechnik ganz normal.⸻📦 FazitDer Membrane Solutions Wasserfilter ist ein zuverlässiger Begleiter für Outdoor-Abenteuer, Krisenvorsorge oder Reisen. Top Preis-Leistungs-Verhältnis, extrem robust und einfach in der Anwendung. Klare Kaufempfehlung für alle, die unterwegs sauberes Trinkwasser brauchen!
Remote on and off button out off alignment so does not turn on most off time. Great little boat thou. –
Can’t wait to try on camping trip

Honestly a MUST have item for every go bag and camping pack you own! extremely compact and lightweight and a lifesaver if you ever need it. Used one once to test the product and have zero concerns that it will work as well again.
Giovanni –
Articolo come descritto. Forse un po’ complicato aspirare acqua ma inserito in una bottiglia di plastica si può filtrare più facilmente.

Tudo ok!
