Ceramic rules!

　　The MSR Miniworks is a little filter that’s huge on value and versatility. No other filter available offers the field maintainability of the MiniWorks filter—that’s why it was selected by the Amphibious Raids & Reconnaissance Division of the U.S. Marine Corps as their filter of choice for fast-and-light missions. The MiniWorks filter is compact, durable, easy to use and can go with you on short day hikes and multi-month international treks. The new EX is 45% faster than the old Miniworks, pumping out 1 liter per minute thanks to its AirSpring Accumulator™. Also, improved handle ergonomics reduce knuckle bashing while filtering. A perennial bestseller and maybe the last filter you'll ever have to buy.
