A gravity fed, pour-through water filtration device includes a chamber housing a spiral filter including a biocidal material and an annular holding chamber. Several porous separator disks, a volume of filtration media, and a cyst membrane are positioned beneath the spiral filter and holding chamber.

A gravity fed, pour-through water filtration device includes a chamber housing a spiral filter including a biocidal material and an annular holding chamber. Several porous separator disks, a volume of filtration media, and a cyst membrane are positioned beneath the spiral filter and holding chamber. The device is effective in significantly reducing the number of bacteria, viruses and cysts present in the filtrated water.

[ I claim:] [40.] A method for removal of cysts from a liquid, comprising the steps of:a) placing a filter into communication with a supply of liquid from which cysts are to be removed, said filter including a porous cyst removal structure having pore sizes operable to trap cysts from the liquid flowing through the structure; andb) directing said supply of liquid into said filter under gravity fed pressure only such that said porous cyst removal structure is effective to remove cysts from said liquid under non-pressure and only gravity operated influence, wherein said filter is mounted to an open reservoir in communication with said supply of liquid.
