Mesh filters are typically used in commercial kitchen hoods. Heavier-than-air grease particles strike and adhere to the layers of mesh inside the filters. Mesh filters are suitable for filtering of grease vapors and oil mists in the food industry. They can also be used as dust filters in industrial processes in general. These filters are installed at an angle, generally 45° to 60°, to allow grease to drain into the hood’s collection channel. Mesh filters are safe to use and easy to clean and do not allow grease to drip on to food or equipment beneath.
