Ensuring safe drinking water anywhere you go, the MSR MiniWorks EX Purifier System consists of high-efficiency pump filter and 50 Aquatabs purification tablets.

Utilizing an AirSpring Accumulator, the microfilter can filter up to 1 liter of water per minute and is effective against bacteria and protozoa. An activated carbon core helps to eliminate unpleasant taste or odor. Its field-maintainable design allows the filter to be cleaned and restored to full efficiency without any need for tools. This ensures reliability even in remote backcountry situations.

While microscopic viruses could slip through the filter and threaten safety, the Aquatabs purification tablets address that threat. Each tablet treats up to 2 quarts of clear water and is EPA-registered as effective against viruses, bacteria, and giardia when allowed a 30-minute treatment time. Fifty tablets are included with the system.

Likes: Love how easy this filter is to use, and strongly prefer the pump to gravity filters. Used it for our recent hike of the the Teton Crest Trail and couldn’t be happier.

Dislikes: Nothing in particular

Water filter is very nice
Reviewed by Brian D. - August 4, 2018

Likes: Convenient, small, easy cleaning, can filter right from my kayak.

Dislikes: Only can filter about 3 liters of water before flow is almost choked off due to needing cleaning. However, it is still very easy to clean. Just wish I could get more filtered water out of it in between cleanings.

requires maintenance
Reviewed by Andrew K. - July 21, 2018

Likes: this is a large filter, but it feels lightweight compared to my cooking tools, the MSL Whisperlite.

Dislikes: this filter recommends boiling the ceramic element for sterilization after 7 days of use. the ceramic element requires a large pot to fit it.
