I purchased the TRK Drip Filter (Gravidyn) as a gift for a relative (for home use) in southeast Asia whose water supply is from a well. The criteria were: ceramic element, compact, plastic or synthetic housing. As I've used Katadyn Combi Filter for backpacking and occasionally at home for 6 years, Katadyn was high on my list. IMO, ceramic elements give the best filtration. The initial cost is high but their value is realized through durability and long life. This unit has been in service since January '06, filtering ~10L/day or a total of ~3,300L (864 gallons) so far. The Activated Carbon (A/C) portion of the filter is effective for 6 months but the ceramic is good for 39,000 gallons (~148,980L). What I like most about this filter: fast flow rate (3 elements), impregnated silver-oxide prevents fungus/mildew growing on the element.
