Abstract
Systems, devices, and methods of filtering water include a dome shaped lid and middle disk to separate filtration media materials. The domed shaped lid eliminates air locks in the filter media that can slow or stop the filtration process. A flow control output port regulates the flow level and flow speed of the filtered water. An angled flow output port improves flow by accelerating flow at an angled bottom section of the filter. Water permeable filter bag materials house the filter media. An additional washing process improves the taste of the filtered water. A color change resin in the mixed bed resin indicates expiration of the filter. Similarly, a filter expiration indicator assists users in determining when a filter should be replaced. An integrated TDS meter is used for testing the filtered water. The devices can be used individually or in combination to provide performance improvements.
