how long does a sub zero water filter last?

The lifespan of a Sub-Zero water filter can vary based on the model of the refrigerator and the water quality in your area. Generally, Sub-Zero water filters are designed to last approximately six months under typical usage conditions. However, if your water supply has higher levels of impurities, the filter may need replacement more frequently. Some Sub-Zero refrigerators come with a filter replacement indicator, which can help remind you when it's time to replace the filter. Regularly replacing the water filter every six months ensures that it continues to effectively remove contaminants, providing clean and safe drinking water from your Sub-Zero refrigerator.
