900404092 Genuine Round Carbon Filter Pack of 2 ULX254 CF110 for Electrolux, Westinghouse Rangehoods BRA603SX-F BRA903CPX-F BDRA603TBX BDRA903TBX

If your rangehood recirculates air back into the kitchen instead of venting outside, it relies on carbon filters to deal with cooking smells. Part 900404092 is a genuine pack of two round active carbon filters, also known as ULX254 and CF110. It's listed for Electrolux and Westinghouse rangehoods and is on file for the BRA603SX-F, BRA603SW-F, BRA903CPX-F, BDRA603TBX and BDRA903TBX models.

Rangehood not clearing cooking smells?

In recirculating mode, air is drawn up through the metal grease filters, then through these carbon filters before it's blown back into the room. The activated carbon soaks up odours from frying, curries and fish. Once it's saturated it stops working, even though the fan still runs and the hood sounds normal. Lingering smells after cooking are the main sign. Unless your manual says otherwise, carbon filters are replaced rather than washed, on the schedule set out in your rangehood manual. Ducted hoods that vent outside don't need them.

Part details

• Genuine part 900404092
• Pack of 2 round filters
• Active carbon (charcoal) media
• Also known as ULX254 and CF110
• For rangehoods running in recirculating mode

Changing the carbon filters

Switch the rangehood off at the wall or isolator and let it cool if it's been running. Remove the grease filters to get to the motor housing. Round carbon filters usually twist or clip onto each side of the fan, so remove the old pair and fit the new ones the same way. Refit the grease filters and reset the filter reminder if your hood has one.

Questions about this part

Do I need to replace both filters?

Yes. The pack includes two because these hoods generally use a pair, one each side of the fan. Both saturate at the same rate, so change them together to keep the hood removing smells properly.
