No, standard Brita pitcher filters and carbon block faucet filters do not remove sodium from softened water. Standard pitcher filters utilize activated carbon and ion-exchange resin primarily designed to reduce chlorine taste, odor, heavy metals like lead, and organic impurities, but they lack the microscopic membrane filtration required to extract dissolved sodium ions. If you want to remove sodium from softened drinking water, you must install a dedicated reverse osmosis (RO) drinking water system under your kitchen sink, which utilizes a semi-permeable membrane to strip dissolved salts. Verification: Test filtered water with a total dissolved solids (TDS) meter to confirm sodium and mineral levels.
