Amazing Service
Because you deserve it.
Fast and easy to use, the MSR Guardian Purifier pump uses advanced hollow fiber filter technology originally developed for the military to remove viruses, protozoa, bacteria, and sediment from even the dirtiest water.
Description
- Ultimate protection against water contaminants: The Guardian meets NSF protocol P248, the testing standard used by U.S. military, for the removal of viruses (99.99%), bacteria (99.9999%), protozoa (99.9%), and sediment from "worst-case" water conditions.
- Fast flow rate for quick and easy purification: The pump-action filter has a flow rate of 2.5 liters per minute and since the 0.02 micron hollow-fiber filter removes viruses as well as other contaminants, there's no need for chemicals, bulbs, batteries, or waiting for secondary measures to take effect.
- Self-cleaning action maintains performance without clogging from sediment: The Guardian self-cleans on every stroke, providing consistently fast flow rates with zero hassle; there's no backflushing or filter-scrubbing ever required.
- Long-lasting performance and durability for peace of mind: The removeable and replaceable hollow fiber cartridge treats up to 10,000+ liters. The field-maintainable design is impact resistant and engineered to withstand heavy use, freezing, and harsh environments.
