Now you can clean the air without raising the noise level with Thermador's new Silent Series hoods: Thermador's quietest and most elegant hoods yet. With ventilation power from 400 to 1,000 CFM, these systems tackle unwanted smoke, grease, heat and odors, yet are up to 25% quieter than most models. The fresh new design of the HS and HSB hoods features a gracefully curved front panel and traditional styling, while the revolutionary HST model is uniquely sleek and modern. Controls are easy to reach, lighting is bright and convenient, and some hoods even let you know when it's time to clean their dishwasher-safe filters.
