Goodman HVAC systems use standard pleated air filters in nominal sizes. The most common Goodman filter sizes are 16x20x1, 20x20x1, 14x20x1, though exact sizes vary by model. Always check your existing filter or your owner's manual to confirm the correct size before ordering.
For most Goodman residential systems, a MERV 8 filter provides the right balance of filtration and airflow. Homes with pets or mild allergies may benefit from MERV 11. MERV 13 provides the highest filtration but may slightly reduce airflow on some systems — check your manual if unsure.
How often to change your Goodman filter: Every 90 days for a 1-inch filter, every 6–12 months for 4-inch and 5-inch media filters. Set a free reminder and we'll email you when it's time.
