An adaptable water filtration device including an upstream housing defining an upstream chamber. A filter mount is coupled to the upstream housing and extends into the upstream chamber. A first filter is removably disposed in the upstream chamber and is detachably engaged with the filter mount. The first filter is configured to filter a first contaminant from the contaminated water. A second filter is removably disposed in the upstream chamber and is detachably engaged with the filter mount. The second filter is downstream of the first filter and configured to filter a second contaminant from the contaminated water through adsorption. The water filtration system is configured to enable selective adaptation of the filtering characteristics thereof by a user by selectively disposing the first and second filters in the upstream chamber to achieve a prescribed filtering effect on the contaminated water. A prefilter may be included to prevent downstream clogging.
