Hold the filter reset button for 5 seconds: Once the filter is installed correctly, press and hold the filter reset button for 5 seconds. Doing so will reset the filter’s internal capacity indicator, which keeps track of how much water has gone through it. This must be done every time a new filter is installed or replaced. The reset button is usually marked with a small triangle symbol on the front of the refrigerator. Make sure to keep pressing and holding down the button for 5 seconds until you hear an audible beep or see the light come on, indicating that the reset is complete.

Discard water for a few minutes: Before using your new sub-zero water filter for the first time, discard a few gallons of water by running it through the system. This is to ensure that any dirt or debris in the system is flushed out before you start drinking and cooking with this filtered water.

Discard the first bucket of water: After all, parts are installed, flush the filter for at least 15 minutes to clear any air or debris. During this time, discard the first bucket of water that comes out. This water may contain sediment from the installation process and should be disposed of properly. Continue collecting filtered water in buckets until the flow is clear and free of particles.

Sings For Changing The Water Filter

Your refrigerator water tastes terrible: If the taste of your fridge water has become unpleasant, it may be time to change your sub-zero water filter.

 Ice maker ice tastes terrible: If you have an ice maker and the ice it produces tastes bad, there could be several reasons for this. One possible cause of bad-tasting ice is a dirty sub-zero water filter. A clogged filter can reduce the water flow to the ice maker resulting in cloudy or off-flavored ice cubes.

The dispenser’s water pressure appears to be decreasing: If you’ve noticed that the water pressure coming from your sub-zero filter dispenser has decreased, there are several possible causes. It could be due to a clogged filter. It’s essential to routinely replace your sub-zero filters according to the manufacturer’s recommendations – usually every 6-9 months for most models.

Containments That Sub-Zero Water Filter Removes

Sub-zero water filters are designed to improve the quality of your drinking water by reducing a range of impurities and contaminants. The filter can remove sediment, chlorine, lead, cysts, turbidity, bad taste, and odors from tap water. It also helps to reduce the levels of volatile organic compounds (VOCs) such as benzene, toluene, and xylene.

The filter will also eliminate bacteria, algae, or other microorganisms in your drinking water that can cause illness. Additionally, sub-zero filters are designed to reduce the number of heavy metal particulates, including copper, mercury, and lead, from entering your tap water supply. By reducing the number of contaminants, you can be sure that the water you are drinking is safe and healthy.


What does certification mean on a refrigerator water filter?

Certification assures that a refrigerator water filter has been tested to meet industry standards and criteria.  Refrigerator water filters certified by NSF International are rigorously tested to verify they meet strict public health standards.

Will a refrigerator water filter disinfect the water?

No, a refrigerator water filter will not disinfect the water. A sub-zero water filter is designed to reduce contaminants, such as chlorine, sediment, and other particulates, from your drinking water that can affect taste and odor. It does not use any chemical or ultraviolet light to disinfect the water.

What does activated carbon means?

Actiiated carbon means

Activated carbon is a critical ingredient in the sub-zero water filter. It effectively removes sediment and other impurities from your drinking water, providing clean and safe filtered water. Activated carbon attracts and traps impurities as they pass through its porous surface, allowing only purified water to pass through.

Can I get a disease from drinking water from the fountain?

No, you cannot get a disease directly from drinking water from a fountain. However, it is essential to remember that the water in some fountains may not be filtered or treated as it would be if you used a home filtration system such as one with Sub-Zero filters. Without this treatment, the water can contain potentially harmful contaminants such as heavy metals, pesticides, and other pollutants.


Installing a Sub-Zero water filter is an easy and affordable way to improve the quality of your home’s drinking water. It uses advanced filtration technology to reduce contaminants, impurities, and odors from your tap water, making it safer for you and your family to drink. Before installing the new filter, read the instructions carefully and double-check all connections. You can enjoy clean and safe drinking water by installing your new Sub-Zero water filter for years to come.
