## Long description

MSR Guardian Purifier manual water filter, grey — 2.5 L/min, 490 g, 210×120 mm is a portable pump-style purifier engineered to deliver treated drinking water from natural sources. Designed originally for demanding military use and adapted for outdoor enthusiasts and emergency kits, the Guardian provides a high minimum flow rate of 2.5 litres per minute while weighing 490 g. The unit’s hollow fiber filtration and integrated viral protection enable safer water in a wide range of field conditions, including turbid or microbiologically contaminated sources.
Advantages
The Guardian purifier combines a robust mechanical pump with an advanced hollow fiber membrane to remove protozoa, bacteria and many viruses, offering viral-level protection uncommon in manual field filters. Its durable construction withstands heavy use and abrasive water, and an internal self-cleaning mechanism restores flow without disassembly. The purifier’s consistent high flow rate and compact dimensions (210 × 120 mm) make it practical for group use, while the 490 g weight keeps it suitable for backpacking and emergency kits.
Suitable for
 Camping and backpacking trips where reliable, fast water treatment is needed
 Hiking in remote areas with untreated surface water sources
 Travel to regions with uncertain water quality, including developing nations
 Emergency preparedness kits and disaster response where potable water must be produced on site
 Expeditions and group outings requiring high daily water throughput
Key specifications
 Minimum flow rate: 2.5 litres per minute
 Weight: 490 grams
 Dimensions: 210 × 120 mm
 Filtration technology: hollow fiber membrane with viral-level protection
 Operation: manual pump purifier with self-cleaning action
 Typical use: direct pumping from natural water sources to containers
How to use
Attach the intake hose to the MSR Guardian purifier and place the intake strainer in the water source. Prime the pump as instructed by the manufacturer and begin pumping steadily to deliver treated water to a clean container. Use the built-in self-cleaning feature periodically to maintain flow rate: follow the prescribed backflush routine or operate the cleaning cycle as directed. Always follow local guidance for safe water handling and avoid contaminating the clean-side hose or container during use.
Usage recommendations
Pre-filter highly turbid water when possible to extend filter life and maintain flow. Regularly perform the purifier’s self-cleaning cycle after heavy use or when flow decreases. Store the unit dry and partially disassembled according to the manufacturer’s instructions when not in use long-term. Replace any worn hoses or seals promptly and follow maintenance guidance to ensure consistent performance and viral-level protection.
