The DECANTUS utilizes the Bernoulli effect where the reduced pressure of a stream of fluid draws an air flow through diagonal thin tubes inside the DECANTUS. The wider opening on top and larger liquid capacity of the top reservoir bowl makes pouring into DECANTUS easier than the Vinturi. The DECANTUS Slim is a streamlined version of the DECANTUS Deluxe, but without the handles. Stands 5" high and 2 3/4" wide at top. Includes Slim Aerator, Base, Velvet Storage Pouch, and Cleaning Brush. 2 3/4" W x 5" L
