Maintain your Humidifier with the SPT Replacement ION Exchange Filter for SU-4010
The SPT Replacement ION Exchange Filter is the key way to prevent the chalky buildup around your home. This is often the result of minerals and calcium in the water. Humidifiers alone can’t get rid of these deposits, so they need to be filtered out.
