This Brink FLAIR Kitchen grill replacement filter should be used in combination with the Brink KITCHEN EXHAUST GRILL. The kitchen filter traps grease and cooking particles and keeps your ductwork clean. The kitchen filter should be changed every six months or as needed based on cooking frequency. The Brink kitchen exhaust should be located a minimum of 6' from the cooktop. To replace the kitchen filter, slide, then pull on the front grate of the KITCHEN EXHAUST grill.
