The filters should be changed every 3 months to ensure optimum extraction performance, although this may vary depending on what kind of cooking you normally do and how often. If you have a Smeg hood with electronic controls, an indicator light will tell you when it's time to change the filters. Clean filters are essential for optimum hood performance.
Perimeter filtration systems, a feature of certain Smeg hoods, offer extremely quiet operation and very effective extraction.
We recommend using special Smeg cleaning products, such as the XSPLEND-2 detergent spray and the PAMI-1 microfibre cloth, which is slightly dampened. The use of solvents or reactive substances should be strictly avoided.
