This miniature marvel of ventilation technology is both discreet and effective. The svelte 1-1/8-inch thick screen with a hardened glass insert slides back under the top cabinet after use leaving only the narrow handle visible, while an integral fluorescent strip illuminates the cooking area evenly with no glare. For all its good looks, this model actually reserves its most impressive feature for the ears: despite its impressive ventilation performance, the double-inlet fan makes barely a whisper. Three power levels plus an intensive mode are provided. The intensive mode runs for three, five or ten minutes as required before returning the ventilation hood to its previous setting. Installation is straightforward, too, so the AH 900 can be installed easily and ready to use in nearly no time.
