The carbon filter in your cooker hood cannot be cleaned and requires replacement to ensure proper function. Regular replacement is essential as carbon filters absorb grease and cooking odours, improving air quality and kitchen recirculation. This maintenance also reduces fire hazards by preventing the build-up of grease and cooking oil particles. For optimal efficiency, it s recommended to replace carbon filters at least once a year. This ensures your cooker hood continues to operate effectively, maintaining a clean and safe kitchen environment.
