If your Lamona or Beko fridge uses a short narrow cartridge with a twist and lock head then you require the newer style filter. This fits Lamona HJA6110, Stoves HJA6110 and Beko fridges.
The filter itself has several part references depending on the manufacturer of the fridge but the most common include 4874960100, 4346650401 and 9256712.
This filter is a bespoke filter, and very difficult to source - With customers in the UK being charged upwards of £90 for the manufacturer's original part. The FilterLogic range offers customers a high quality sintered carbon block solution, offering similar performance to the original at a substantially cheaper price.
