Available in both plastic and metal, East Coast Filter Sales and Service stocks Mesh/Grease filters; most often used in commercial kitchen spaces such as food prep areas and restaurants to act as a sieve trapping cooking oil and grease present in the air. The filters we offer remove easily and can be washed with soapy hot water, for repeat use – preventing excess grease buildup in your ventilation system so your space continues to remain clean and sanitary, while still allowing airflow.
