## Customer Reviews

### ⭐⭐⭐⭐⭐ Quality filtering system.
*by H***I on November 27, 2025*

Haven’t try it yet but should be perfect for our boat trip in other countries.

### ⭐⭐⭐⭐⭐ My go-to filter
*by S***N on December 23, 2025*

very happy with this. I spend a great deal of time in the backcountry. These are lightweight, durable, and efficient.

### ⭐⭐⭐⭐ Works great, but...
*by H***Y on November 9, 2025*

Filters great, large capacity, and quick. Hose plugged right into the QD on my water bladder. Minus one star because it is hard to fill in slow moving water. I had to cut a corner from a gallon zip lock bag, fill that with water, and use that to fill the bladder. Overall, very useful.
