Aquamira Red Filter

AQ-1.jpgBight that Valve!*

Well—the bite valve came off the filter and I had to futz with it to put it back on the filter. May be a hazard of bite valves in general.

Was told about Aquamira filter systems by a veteran mountaineer friend. He found it the most efficient way of staying supplied with water in the backcountry. Last trip I was dehydrated due to the hassle of finding a good source to use my hand-pump filter when I needed water. I decided on the Aquamira Red filter system as it additionally filters out most viruses also—a Covid precaution.


With lots of traffic even in the furthest backcountry by ourselves and animals it is prudent to up the game of filtration. I will use it to filter drinking water right out of any source to immediately drink from the bite valve and also have a 32oz Nalgene for transfer to the Aquamira.

The size, design and composition of the bottle and filter is excellent. If you are counting ounces/grams hard to find a lighter combination. The way I use it is for personal consumption. For groups you need a pump or hang-bag system.

Was so impressed bought one for the household for emergency situations.


Now I feel much safer on the trail drinking water that is shared by so many creatures.


Several high country backpacking trips over two years. Used to use the classic pump, but this is lighter and you can drink immediately. Use a Nalgene bottle for cooking water—boil that water.
