how often to replace sub zero air purification

Sub-Zero recommends replacing the air purification cartridge in their refrigerators every 6 to 12 months. However, the actual replacement frequency may vary based on factors such as the model of your refrigerator, the level of air pollution in your home, and how frequently you open the refrigerator doors. Regular replacement of the air purification cartridge is essential to maintain a fresh and odor-free interior, as the cartridge becomes less effective over time as it absorbs impurities from the air. To ensure optimal performance and air quality, check the replacement indicator on your refrigerator or refer to the manual for specific guidelines on when to replace the air purification cartridge.
