Zusammenfassung:The present invention relates to a filter comprising a carbon block enveloped with spiral wound layer of non-pleated fabric enveloped with spirally wound layer of pleated fabric. The combination of these three elements gives more than 3.5 log cyst removal from contaminated water, over prolonged usage of more than 2300 liters of water. The invention also relates to a gravity filtration device that comprises the filter of the invention. A method of filtering water is also claimed where the water flows first through the pleated fabric, then through the non-pleated fabric and then through the carbon block.
