  • Pump is fully field maintainable and does not require tools for complete disassembly
  • Included Quick-Connect™ bottle cap interfaces with MSR hydration products, Nalgene bottles and other containers with 63 mm threaded openings (bottle not included)
  • Quick-Connect cap allows the pump to attach directly to the bottle or hydration bladder for the most convenient filling (bottle/bladder not included)
  • Included prefilter attaches to the end of the intake hose and blocks larger contaminants from entering the microfilter

Great backpacking filter

I’ve had this filter for years, and it has always worked perfectly for me. Easy to use, easy to clean, and easy to pack. I tried to buy one for a friend recently on rei.com. The website said low stock, so I bought it, only to have my order cancelled, stating they were out of stock. Anyway, excellent filter.
