Kenmore 46-9999 Water Filter Guide: Which Frigidaire Filter You Actually Need (2025)
Kenmore 46-9999 Water Filter Guide: Which Frigidaire Filter You Actually Need (2025)
The Kenmore part number 46-9999 (also listed as simply 9999) is used by Sears/Kmart as a cross-reference for Frigidaire-built Kenmore refrigerators (model numbers beginning with 253.xxxxx). However, depending on which specific Frigidaire-built Kenmore model you own, this cross-reference may resolve to either the Frigidaire ULTRAWF or the Frigidaire PAULTRA — which are physically different filters that are not interchangeable. The definitive identification method is the label on your installed filter.

Kenmore 253.xxxxx refrigerators manufactured before approximately 2010 may use the older PureSource 2 (WFCB or WF2CB) filter — a round, larger-diameter filter with a twist-in mechanism at the bottom of the refrigerator interior, distinct from the push-in ULTRAWF and PAULTRA in upper interior housings. Some older Kenmore parts catalogs listed the “9999” cross-reference for these PureSource 2 units as well, creating significant confusion. If your Kenmore 253.xxxxx is over 15 years old and the filter is a round cartridge at the bottom interior — you likely have a PureSource 2 / WFCB, not an ULTRAWF or PAULTRA. The three filter types are physically incompatible. Confirm from your installed filter label, which will show WFCB, WF2CB, ULTRAWF, or PAULTRA directly. Contact our support team with your full Kenmore model number if your filter shows a legacy part number not covered in this guide.
As the FTC’s Magnuson-Moss Warranty Act guidance confirms, using NSF-certified compatible filters does not void your Kenmore refrigerator warranty — regardless of whether the fridge was manufactured by Frigidaire, Whirlpool, or LG.
