Abstract
A bottle comprises a cap, a reservoir having an open top closeable by the cap, and a filter holder that houses a filter, the filter holder being coupled to the cap such that a liquid in the reservoir is filtered by the filter as the liquid is being consumed, and the filter is fluidly decoupled from the reservoir when the cap is disengaged from the reservoir. Preferred filters can be constructed out of high reactivity carbon mixture, activated carbon, iodinated resin, combinations thereof, or any other suitable compositions for filtering water or other liquids, and can be molded into any suitable size and shape. Preferred filter holder can have a top portion and a bottom portion that couple together via a snap fitting, mating threads, or any suitable means, which allow access to the filter, and which have numerous vents that allow liquid to freely flow through the filter.
