Owners of Frigidaire refrigerators with ice makers or water dispensers should rely on authentic water filters to maintain the quality of ice and water. If you regularly use these features on your fridge, replace your Frigidaire water filter at least every six months, or more often, based on your usage and the capacity of the filter model. Many refrigerator models feature filter change indicator lights to make it easier to tell when a new filter is needed. Your fridge will require a particular PureSource replacement filter designed to fit the filter housing.

Frigidaire water filters are cartridges specifically designed to fit certain refrigerator model numbers manufactured by this brand. It is important to choose the right PureSource cartridge, as these replacement filters are designed to install in different ways depending on the housing on your refrigerator model. 

Inline water filters attach directly to the water supply line and are compatible with any brand or model of refrigerator.

Genuine Frigidaire water filters provide up to three levels of carbon filtration to reduce the amounts of chemicals and contaminants found in drinking water. These NSF-Certified filters typically outperform off-brand replacements made by independent manufacturers. When you purchase an authentic filter, you can count on the replacement to function as intended for the complete capacity rating and operational life guaranteed by Frigidaire.

Even though replacement filters by other brands may cost less up front, the quality of the water and the longevity of the filter are likely to limit the value of these options over time. Customers point out that some replacement filters are not designed to properly fit Frigidaire models. You should never try to jam the wrong filter into your fridge or alter or manipulate the filter housing in any way that may void your refrigerator warranty. Instead, reference your refrigerator manual and search for the right water filter for your fridge model number. Regularly replace the filter to maintain the quality of ice and water dispensed from your fridge.
