Highlights of the " Platypus GravityWorks 4.0L " water filter system

• No pumping: Simply fill the dirty container, hang it up, and let gravity do the work—yes, filtering water can be as easy as filling, hanging, and relaxing.
• Fast: Filters up to 1.75 liters per minute; microfilters last for up to 1,500 liters of water.
• Effective: Each microfilter is individually tested to ensure it meets all EPA and NSF guidelines for removing 99.9999% of bacteria and 99.9% of protozoa (including Giardia, Cryptosporidium, E. coli, Salmonella, and Cholera).
• Lightweight and compact: The system weighs 326 g and packs down smaller than most 1-liter bottles.
• Suitable for groups: The total capacity of 8 liters (4.0 L filtered + 4.0 L unfiltered) easily supplies water to larger groups.
• Cleanable on the go: The microfilter can be easily backflushed in 4 seconds to maintain filter performance.
• Advantage of hollow fibers: Hundreds of tiny hollow fibers allow the microfilter to filter water faster than conventional filter media.
• Easy filling and dispensing: Filling with water is simple—just open the lid, scoop in water, and close it; the flow of filtered water can be regulated using the inner tube clamp.
