Compact water filter for hiking, cycling, camping and travel. The hollow-fibre membrane with 0.1 µm pore size mechanically retains suspended matter, turbidity and microorganisms of this size and larger – no chemicals, no pump.
Drink straight from the water source or screw onto a PET bottle (Ø 28 mm thread)
Filter capacity up to 5,000 litres depending on water quality, flow approx. 800 ml/min
Light (52 g), 140 mm long, Ø 36 mm; with silicone mouthpiece, drinking pouch, carabiner and cleaning syringe
Backflushing with the syringe keeps the flow high; use at 0–32 °C, protect from frost
Note: for fresh water from lakes, rivers and streams only – not for salt water or chemically contaminated water. Dissolved substances (e.g. salts, heavy metals) are not removed.

„A very sturdy, recommendable shower hose. Very important and decisive - is the very sturdy - - INNER hose - probably a nylon material combination, which can easily withstand several twisting movements. My previous - cheap - shower hoses had a very simple, very thin rubber hose, which burst twice after intensive use, causing the annoying water mess. I therefore bought 3 of these at once.“

Ein sehr stabiler empfehlenswerter Brauseschlauch. Ganz wichtig und entscheidend - ist der sehr stabile - - INNEN-Schlauch -vermutlich eine Nylon-Materialkombination, der auch öfter mal mehrere Drehbewegungen problemlos standhält. Meine vorherigen -billigen- Brause-Schläuche hatten einen ganz einfachen sehr dünnen Gummischlauch, die 2 x nach intensiver Nutzung geplatzt sind, mit der dann ärgerlichen Wasser-Sauerei. Habe somit gleich 3 Stück hiervon gekauft.

„Quickly delivered and okay. The hose inner diameter is a bit small with its hydraulic inner diameter. The flow rate is therefore noticeably lower than with my old armored hose; a pity.“

Schnell geliefert und i.O. Der Seelengewebelauch ist mit seinem hydraulischen Innendurchmesser etwas klein. Der Volumenstrom ist daher merkbar geringer als bei meinem alten Panzerschlauch; schade.
