How Often Should You Replace Your Furnace Filter?

Replacing your furnace filter is one of the simplest yet most important HVAC maintenance tasks.

General Guidelines

• Standard filters (1-2 inches thick): Every 1-3 months
• Thicker filters (4-5 inches): Every 6-12 months
• HEPA or high-efficiency filters: Check every 2 months

You should also consider: pets in the home, allergies or asthma, usage frequency, and local air quality.

Why It Matters

Neglecting your furnace filter can lead to reduced airflow, higher energy bills, poor indoor air quality, and unnecessary strain on your system.
