Basic Spun Glass HVAC Filters (Low MERV) (6)

Basic spun glass HVAC filters, often rated in the low MERV range, provide simple and affordable protection for heating and cooling equipment. Designed to trap larger particles like dust, lint, and debris, these filters help prevent buildup on coils and fans while allowing maximum airflow. While not intended to significantly improve indoor air quality, spun glass filters are widely used in residential and light commercial systems where low cost and basic system protection are the main priorities.
