Provides the initial stage of air filtration by capturing grease, smoke particles, dust, and other larger airborne contaminants before they reach the primary filtration components. The Wells 22618 Universal Pre-Filter MERV-8 helps reduce contaminant buildup within the ventilation system while supporting consistent airflow. Its nominal 16" × 20" × 2" dimensions are intended for applications requiring the specified pre-filter size.

Filtration Performance:
Captures larger airborne particles as air passes through the filter media, reducing the amount of grease, smoke, and dust that reaches downstream filtration stages. This staged filtration helps limit contaminant accumulation and supports effective air movement through the ventilation system.

Grease and Particle Filtration:
Captures grease, smoke, and airborne particulates from the cooking exhaust stream before the air reaches downstream filtration components. This pre-filtration stage helps reduce the contaminant load entering the primary filtration system.
