MERV 8 vs MERV 11 Which Is Better


When comparing MERV 8 and MERV 11 air filters, the choice depends on your specific needs and priorities. MERV (Minimum Efficiency Reporting Value) is a rating system that measures a filter's ability to capture particles of different sizes. Generally, MERV 11 filters offer higher filtration efficiency than MERV 8 filters, capturing smaller particles and potentially providing better air quality. However, MERV 11 filters may also restrict airflow more than MERV 8 filters, which could affect HVAC system performance and energy efficiency. Therefore, it's essential to consider factors like air quality requirements, HVAC system compatibility, and maintenance preferences when deciding which is better for your situation.
