Excerpt: In our ongoing Filtrete Filter Showdown, we were intrigued by the MERV 11, 3-Month Power Flow option. The 16x25x1 filter proved to be a standout choice, offering MPR 1000 filtration that excels at trapping microparticles while maintaining efficient airflow. The electrostatic pleated design ensures a snug fit, and with Micro Allergen Defense, we noticed a significant reduction in airborne irritants in our home. The two-pack deal allowed us to replace filters without delay, ensuring consistent performance. While the actual size (15.719 x 24.72 x 0.84 inches) was slightly different from the listed dimensions, it didn’t hinder usability. Overall, this filter balances allergen removal with long-term convenience, making it a reliable option for AC systems seeking reliable defense.
