Type I hoods must be equipped with which type of filter?

Type I hoods, commonly found in commercial kitchens and cooking environments, are specifically designed to manage heat, smoke, and grease that result from cooking activities. One of the critical components of a Type I hood is the grease filter, which plays a key role in removing grease particles from the air before it is exhausted.

The function of a grease filter is to capture and contain the grease vapors and particles that could otherwise go through the exhaust system, potentially leading to fire hazards or buildup within the ventilation system. These filters are designed to withstand high temperatures and are made from materials that effectively trap grease, ensuring safety and optimal performance of the kitchen ventilation system.

While activated charcoal filters and standard air filters serve important functions in different contexts, they are not suitable for use in Type I hoods. Activated charcoal filters are often utilized in applications requiring odor control, while standard air filters are meant for improving indoor air quality, not for grease removal. Mesh filters might capture some particulates but do not provide the same level of efficiency in handling grease as grease filters do.

Therefore, the requirement for Type I hoods to have grease filters is critical for maintaining safety standards and ensuring proper ventilation in commercial cooking environments.
