How often should I replace my air filter?

Replace your air filter every 3 months under normal conditions. If you have pets or high dust levels, consider replacing every 4-6 weeks for optimal air quality.

What does MERV 11 mean?

MERV (Minimum Efficiency Reporting Value) rates how well a filter captures particles. MERV 11 filters capture 95% of particles as small as 1 micron, including most household allergens and pet dander.

Will a better filter affect my HVAC system's performance?

No. Quality filters like MERV 11 are designed to maintain proper airflow while filtering. However, always follow your system's recommendations—some older HVAC systems perform better with lower MERV ratings.
