Top Takeaways
Replace your 16x20x1 HVAC furnace filter every 1–3 months

Why Replacing Your HVAC Furnace Filter Matters
Your HVAC system circulates air throughout your home—and that air often carries particles like dust, pet dander, pollen, mold spores, and even bacteria. A clogged or low-efficiency filter allows these pollutants to keep cycling into your living spaces.
But when you replace your 16x20x1 HVAC furnace filter with a higher-quality model (especially those rated MERV 11–13), you trap more airborne contaminants and support better airflow. That means:
Fresher, cleaner air
Fewer allergens and asthma triggers
Less visible dust buildup
Reduced strain on your HVAC unit
Replacing your filter every 1–3 months creates a noticeable difference in how your home feels—and breathes.
