MERV 11 is generally better than MERV 8 as it offers higher filtration efficiency, capturing smaller particles and a greater range of allergens, including pet dander, pollen, and dust mites. This is particularly beneficial for those with allergies or respiratory issues, as it ensures cleaner indoor air. However, MERV 11 filters may reduce airflow slightly more than MERV 8, so ensure your HVAC system can handle it.
