An apparatus provides a water bottle mouthpiece attachment which can filter microplastics and other contaminant substances from bottles, particularly disposable plastic water bottles. The filter of the apparatus includes a filter housing that is attached to a cap that fits inside a common plastic bottle. Soft rubber rings, tapering from to radially larger on the top to radially smaller on the bottom in a generally conical fashion, ensure a watertight fit to the inside opening of any drinking bottle. A friction closing/opening spout at the top of the filter enables selective opening of the bottle and prevents accidental spillage of bottle contents. The filter housing is also offset from the center, giving space to an air valve that allows air to enter the bottle without disturbing the flow of water from the bottle, thus providing optimal lamellar flow without allowing fluid to escape through the air valve during consumption.

An indicator for management of a filter cartridge for a filtering bottle, the bottle including a container with a neck, a filter cartridge and a cap with a coat. The indicator includes a first ring, a second ring arranged coaxially on the first ring, wherein the first and the second rings are rotatable relative to each other. One of the rings includes markings relating to the filter cartridge arranged around the ring and defining a time unit. The other ring includes an indicating element for indicating a selected marking relating to the filter cartridge by rotating one of the rings relative to the other. The indicator for management of the filter cartridge is also adapted to be mounted around the neck of the container of the filtering bottle under the coat of the cap. Furthermore, a filtering bottle and such an indicator for management of a filter cartridge and a set of a filtering bottle and such an indicator for management of a filter cartridge are described.
