Baffle filters are constructed from opposing baffles. They are typically used in professional kitchens but also found in domestic applications. They are suitable for filtering grease vapors and oil mists. Particles of grease are deposited on the internal surfaces of the specially shaped baffles and are captured by the filter. Baffle filters are installed at an angle that allows grease to drain into the hood’s collection channel. Baffle filters are safe and easy to use and do not allow grease to drip on to food or equipment beneath.
