Tested by IvyEverything in this shop went out on a real trip with me before it earned a listing. Wet, cold, dropped, packed out. This one passed.
Flat, acidic-tasting water has a fix that fits in a shirt pocket. The mineral water filtration rod is a perforated stainless steel tube packed with mineral media: drop it in a bottle or pitcher, give it time to steep, and pour.
Perforated stainless steel shell lets water circulate freely through the mineral core while keeping it contained.
Moved test water from pH 5 to 6 up to pH 8 to 9 in the maker's testing, nudging flat water toward the alkaline range.
Pen-style carry case with a pocket clip keeps it clean between uses and rides in a pack lid or jacket pocket.
No batteries, no cartridges, no moving parts, just a rod you move from one container to the next.
Keep one in the travel kit and better-tasting water follows you around.
