To replace a Rheem filter, first, turn off the power to the unit for safety. Locate the filter compartment, usually found on the front or side of the unit, and remove the access panel if necessary. Take out the old filter, noting its size and orientation, and insert the new filter, ensuring it fits snugly and is installed in the correct direction. Finally, close the access panel and restore power to the unit.
