Question & Answers

Q micron to what size with this filter. also is there a better ceramic filter for getting the cleanest water?
A This is 0.9 micron filter. The Super Sterasyl features 3 stages of filtration: First stage: The first stage consists of Doulton supercarb ceramic which provides genuine sub-micron filtration. The cartridge reduces fine particulate matter, bacteria, cysts and turbidity. Second stage: The incorporation of silver locked within the ceramic structure gives enhanced bacteriostatic and self sterilizing properties, preventing the growth of bacteria. Third stage: An inner core of activated carbon block removes chlorine and organic compounds.
A Going by memory, it's less than 4 microns. As a gravity filter it works very well and I have had no problems at all. As far as I am concerned there are no other filters that are better. If you have a camp with a stream or other source of water this filter is a natural. It will easily filter 5 gal of water a day, no problem.
