Shop Furnace Filters - Keep Your Home Heating Efficient

Fiberglass filters (MERV 3–4) are the most affordable, capturing larger debris like lint and dust. Polyester filters (MERV 5–6) trap smaller particles and pet dander while maintaining good airflow. Pleated filters (MERV 8–13) are ideal for furnaces because they balance airflow with strong filtration for dust, pollen, and bacteria. For most homes, a pleated MERV 8 furnace filter offers the best mix of performance and efficiency.

For allergy relief, use pleated MERV 11–13 filters or orange and white media pads. These capture fine allergens such as pollen, pet dander, and mold spores while allowing steady airflow through your furnace system.

Change standard filters every 60–90 days, or more often if you have pets, allergies, or high furnace use during winter months. Consistent replacement helps maintain airflow and prevents your system from overworking.

In most combined HVAC systems, yes. The same filter slot handles air circulation for both heating and cooling. Just confirm your size and MERV rating match manufacturer recommendations for both modes.
