The MSR Guardian Water Purifier claims to eradicate all biological threats that thrive in natural water sources as it acts as a filter and a purifier. It is safe to use as it doesn’t make use of any batteries, chemicals, UV light or carbon. It is made out of a hollow-fiber design using sophisticated medical-grade fibers that are manufactured tightly to block any microbiological elements.
Making use of .02-micron certified hollow fibers, this water purifier removes contaminants, microbes, viruses and other biological threats out from even the dirtiest of water. The purifier’s unique structure and design instantly back-flushes 10% of its water with each pump, this means you don’t need to manually clean it. It is also extremely durable, as it can endure freezing environments and 6-feet shock-proof feature.
You can expect it to clean up to 2.5 L of water each minute, and since it can provide you 10,000 liters of water before you are required to change the filter which means it may be the last water filter you’ll ever need.
