Sub-Zero Maintenance 101: How to Replace Sub-Zero Water Filter
It can be easy to avoid changing refrigerator water filters when you simply don’t know when to do it. In addition to how to change Sub-Zero water filter, we’ll discuss how often it should be replaced. We’ll also detail some signs to watch for, indicating it should be done sooner rather than later.
How Often to Change Your Water Filter
A Sub-Zero water filter works by screening out impurities, like certain chemicals and minerals, from your home’s water supply. The filter is able to separate these contaminants before they enter your drinking water or water used for ice production. However, over time, these particles build up on the mesh screen of the filter leaving it unable to strain any more out.
So, how long does a Sub-Zero water filter last? We recommend changing the filter every 6 months to ensure cleaner water and ice.
Signs You Need to Change the Filter
Despite this recommendation, you may need to change your filter more often if you notice certain changes in your drinking water and ice. Here are some signs to look out for that may indicate the need for a replacement:
- Your refrigerator water tastes bad
- Ice maker ice tastes bad
- The dispenser’s water pressure appears to be decreasing
