Key benefits Maintains stable suction: keeps the range hood air outlet unobstructed so airflow stays strong and extraction performance does not decay. Cuts cleaning and maintenance: traps grease before it reaches the hood and ductwork, reducing the need for frequent deep cleaning and lowering ongoing maintenance costs. Handles oil cooking: engineered to filter heavy oil smoke produced by stirfrying, deepfrying and other heat cooking methods. Improves kitchen safety: prevents oil from dripping onto the stove surface, reducing slip and fire hazards during cooking. What it does (function) Acts as a prefilter and oil catcher at the hood outlet, intercepting grease and oilladen particles while allowing exhaust airflow to pass . Stabilizes hood performance by preventing buildup that can restrict airflow and reduce suction over time. Compatibility and fit Designed for use with range hoods and kitchen exhaust systems. Check your hood outlet shape and dimensions to confirm fit. Lowprofile design integrates with most hood configurations without obstructing normal operation. Material and construction Built for everyday kitchen use with materials selected to resist oil adhesion and withstand repeated cleaning. Components are removable for easy cleaning and reinstallation, preserving performance over time. Performance and maintenance Improves extraction efficiency by keeping the outlet clear, so the hood performs closer to its rated suction capacity. Reduces frequency of intensive cleaning cycles; routine rinsing or washing of the unit is usually sufficient. Typical use scenarios Home kitchens that frequently use heat techniques such as stirfrying and deepfrying. Busy family cooking periods when grease production is elevated and the hood needs to maintain steady airflow. Small commercial or sharedcooking spaces where reducing maintenance time and avoiding oil drips improves safety and uptime. Installation and care Install at the hood outlet according to your hood's dimensions. Remove and rinse the unit periodically; frequency depends on cooking habits. Regular inspection ensures continued filtration efficiency and safer stove operation.
