Abstract
The present disclosure relates generally to air intake filter assemblies, and more particularly to air intake assemblies for an outdoor portion of a heating, ventilation, and/or air conditioning (HVAC) system. In an embodiment, a filter assembly is configured to filter an airflow entering an air intake of a HVAC unit. The filter assembly includes a first layer of a first coarse mesh, a second layer of a second coarse mesh, and a fine filter disposed between the first layer and the second layer. Additionally, the fine filter includes an upper level and a lower level with respect to the airflow, and wherein the lower level facilitates accumulation of fine debris captured from the airflow entering the air intake of the HVAC unit.
