A strainer; piece of woollen cloth, paper, or other substance, through which liquors are passed for defecation. Filters are now largely employed for the purpose of filtering water, either for drinking or culinary purposes. One of the most successful apparatus for the purification of water for domestic purposes is the ascending filter of Leloge. It is divided into four compartments, one above the other. The upper part, containing the water to be filtered, communicates with the lowest by a tube having a loose sponge at its mouth to stop some of the impurities. The top of the lowest compartment is composed of a porous slab, through which the water passes into the third part, which is filled with charcoal. The water is forced through the charcoal and another porous slab into the fourth compartment, which is furnished with a tap to draw off the filtered water. To enable the filter to be cleaned, there is a movable plug in the lowest part.
