FIELD: filter elements.
SUBSTANCE: invention relates to filter elements installed on devices for dispensing water, for example, coolers. The needle of the bottle receptacle for piercing the membrane of the cork of a container with water is a one-piece rod with a piercing head, made of titanium hydride with the addition of carbon from 0.1 to 2% and silver 999 samples from 0.1 to 10% mole fractions. During operation, the needle penetrates directly into the container and contacts the total volume of water.
EFFECT: due to the porous structure and composition of which the needle is made, the water in the container is purified from bacteria and harmful impurities.
