The OEM Frigidaire PureSource water filter and aftermarket Supco WF284 replacement are very similar when it comes to filtering your water. Both filters are able to filter your water of impurities that you shouldn't drink, such as chemicals and dirt. The aftermarket Supco WF284 is a cheaper alternative to the factory original, while still producing similar results. The Supco WF284 has the same operating temperature, pressure range, and slightly less filtering capacity as the OEM. The main difference between the two filters is that the Frigidaire WF1CB holds the Frigidaire brand name and has an NSF/ANSI rating of 42. This means that the filter was tested against NSF/ANSI standards of reducing chlorine odor and taste in the water. Both models are guaranteed to fit in any refrigerator model that uses the WF1CB filter and come in a convenient 3-pack that will give you 18 months of filtered water.
