Which type of grease filter shall not be used in these systems?

• A. Charcoal filters
• B. Stainless steel filters
• C. Mesh filters
• D. Perforated plate filters

Answer: (C)

Grease filters in kitchen hood systems must be metal and designed to withstand heat while being easy to clean and maintain. Mesh filters don’t meet these requirements because their open, woven structure traps far less grease and is difficult to clean thoroughly. Grease can accumulate in the many tiny channels and spaces, leading to reduced airflow, more buildup, and a higher fire risk. Charcoal filters are used for odor control in non-ducted, recirculating hoods, not as grease filters in ducted systems. Stainless steel and perforated-plate filters are the typical metal options that meet the needed performance and cleaning requirements.
