MSR Guardian Gravity

The original Guardian caused a stir among the outdoor community at the time of its release: designed for extremely demanding conditions, the filter could even withstand freezing and offered exceptionally high performance. Now this same Guardian technology has been applied to a gravity filter design. A 10-liter water bag and gravity operation make this a great choice for group use as well.

Additional images may show bottles and other accessories that are not included in the price.

This model comes with a 10-liter water bag that you can hang from, for example, a tree branch and wait a while – the result is drinkable water. The filtration results meet the requirements of the U.S. military test standard NSF Protocol P248: Guardian Gravity filters at least 99.99% of viruses, 99.9999% of bacteria, 99.9% of protozoa, and also removes sediment and microplastics.

In addition, the filter’s activated carbon element removes, for example, unpleasant tastes from the water.

• Two-stage filtration

• Easy to clean
• Purification rate up to half a liter per minute
• Comes with a stuff sack
• Made in the USA

Note! Water filters or purification tablets do not remove toxins produced by blue-green algae blooms, and therefore cannot make water contaminated by blue-green algae safe to drink.
