Common questions
- Which carbon filter fits the Chef CS902S?
- The Chef CS902S takes the Unilux activated carbon rangehood filter ULX252 (2-pack).
- How often should I replace the carbon filter in my Chef CS902S?
- Every 3 months. It works less well as the filter fills up, so it's worth doing on time.
- Where can I buy the ULX252 in Australia?
- We track 1 Australian seller for the ULX252; the lowest listed price when we last checked was A$30.00 at Chef Australia. Prices are re-checked daily and dated on this page.
- How do I fit the ULX252 in a Chef CS902S?
- No tools, a few minutes: 5 steps, listed on this page with the replacement video where the maker has one.
- What happens if I don't change it?
- Grease builds up in the mesh and the fan pulls less air, so smoke and smells linger; a recirculating hood with a spent carbon filter blows the smell back into the kitchen.
- How do I reset the filter light?
- Most hoods this part fits have no filter reminder. If yours has a filter light, the manual for your model explains the reset.
