Changing the way to manage airborne grease...
Proper use of Safety Shield filters will reduce your exhaust system cleaning demands by at least 75%.
Fire code guidelines in the USA and Canada mandate that kitchen exhaust systems be inspected periodically to assure the system is maintained to clean standards. As the exhaust system is kept essentially grease-free by using Safety Shield filters, this allows for compliance by inspection alone. There is no need to schedule cleaning unless the system condition fails the inspection due to grease buildup. In some hood systems, that could be years!
Replacing the late-night, invasive, messy exhaust system cleanings with simple exhaust system inspections saves considerable money and management time.
