4055375200 Genuine Cold Catalyst Filter Net for Electrolux Group Split System Air Conditioners

Part 4055375200 is a genuine Electrolux group cold catalyst filter net. Cold catalyst filters are an extra filter layer found in air handling appliances such as split system air conditioners, where they are generally used to help reduce odours in the circulating air. Our records don't name the exact appliance, so compare the part number on your old filter, or your model's parts list, with 4055375200 before ordering.

When to replace a cold catalyst filter

Air conditioners pull room air through a coarse dust filter, and some models add a finer cold catalyst layer behind it. Over months of use that layer loads up with dust and residue and does less of its job. Signs it needs replacing include a musty smell when the unit starts, dust visibly caught in the mesh, a torn or warped net, and weaker airflow from the outlet. Cleaning the main dust filters regularly helps the cold catalyst layer last longer, but once it is worn or damaged it is best replaced.

Fit the new one the same way round, refit the dust filters and close the panel securely before turning the power back on.
