Using KDF-55 filtration, it treats chlorine and reduces microorganisms, lead, hydrogen sulfide, iron, mercury, dirt, and odor in the water. $15 for one replacement filter.

This NSF-certified filter system uses coconut shell carbon to reduce the amount of chlorine, lead, and iron in your water, while a KDF copper and zinc blend work to balance out the water’s pH level.

For instance, when it comes to removing heavy metals, using KDF filters that rely on ‘metal scavengers’ like titanium dioxide, activated carbon and whole-home water filters can help.
