When to Replace Your Filter:

Austin Air recommends replacing your filter every 5 years for optimal performance. Signs it may be time to replace:

• You've had the filter for 5 years or longer
• Reduced airflow from the unit
• Return of allergy symptoms or odors
• Visible discoloration of the filter (if inspected)
• Unit is working harder (louder) than usual

Why Choose Genuine Austin Air Filters?

Generic or aftermarket filters may seem cheaper, but they compromise your air quality and can damage your unit:

• Exact Fit: Genuine filters are precision-engineered to fit perfectly—no gaps that allow unfiltered air to bypass
• Certified Performance: Austin Air filters are tested and certified to remove 99.97% of particles—generic filters often don't meet this standard
• Maintains Warranty: Using non-genuine filters may void your Austin Air warranty
• Optimal Airflow: Genuine filters are designed to maintain proper airflow—cheap filters can restrict airflow and strain the motor
• Quality Materials: 15 lbs of activated carbon (generic filters often use less, reducing effectiveness)
• 5-Year Lifespan: Genuine filters last the full 5 years—cheap filters may need replacement sooner, costing more long-term
