When I first started looking into air filters, I quickly learned that MERV stands for Minimum Efficiency Reporting Value. The MERV rating measures how effectively an air filter can capture airborne particles. A MERV rating of 11 indicates that the filter can trap a significant amount of dust, pollen, pet dander, and even some bacteria. This makes it an excellent choice for those of us concerned about indoor air quality.

I found that the dimensions of 20x25x5 inches are essential when selecting a filter for my HVAC system. This specific size fits many standard systems, ensuring a proper seal and maximum efficiency. It’s crucial to measure your existing filter to avoid any fitting issues.
