The picture and specs sheet does not show the filters.
The Zephyr Filter Free Advantage: All cooking residue and grease will be automatically liquefied within the sealed housing and drained into a pair of residue cups. Cooking residue will no longer sift through filters and accumulate in motors and duct work which greatly reduces efficiency and performance over time. Insures the lifelong performance on motors and prevents potential grease fires in duct work. Saves time and cost by eliminating the need to replace expensive filters.
