Features
- Unlike conventional hollow-fiber technology, the advanced medical-grade fibers in the Guardian block viruses—something most other hollow-fiber filters cannot do
- Physically removes viruses, bacteria, protozoa and particulate, including hepatitis A, E. coli, giardia, cryptosporidia and more
- Purifies 2.5 liters per min.
- With every stroke, the purifier uses 10% of its water to flush the contaminants in its filter back into the source; this means you’ll never have to hassle with back-flushing
- Rugged construction is designed to withstand freezing and drops up to 6 ft.
- Cartridge life: 10,000 liters
