3.5 gal gravity feed bucket filter system. Ceramic filter removes 99.9% giardia, Cryptosporidum and other harmful protozoa. Filter contains catalytic Granular Activated Carbon which absorbs chlorine, chloramine used in city water supplies and other Volatile Organic Compounds (VOC's).
To treat water, pour water into top container and it filters through to the bottom container. Thorough filtering takes time so the lower water decanter will fill at approximately 1L per hour.
After 3 hundred gallons the filter can be cleaned and reused.
