Know before you buy
This filter is designed for Carrier FILCAB and MPKA series systems that use a 24" x 25" x 5" box filter. Always verify your current filter's actual dimensions against the 23 3/4" x 24 3/4" x 4 3/8" measurements provided to ensure a proper seal.
A MERV 11 rating indicates that the filter is highly effective at capturing particles as small as 1.0 microns. It is an excellent choice for trapping common household allergens like dust, pollen, and pet dander, providing a noticeable improvement over standard lower-rated filters.
The pleated construction significantly increases the total surface area of the filter media. This allows the filter to capture more debris and maintain better airflow compared to flat-panel filters, which helps your HVAC system run more efficiently.
While higher MERV ratings do increase filtration density, this filter is engineered to balance high-efficiency particle capture with consistent airflow. However, it is important to replace the filter regularly to prevent airflow restriction caused by excessive dust buildup.
For most residential settings, these filters should be replaced every 6 to 12 months. Factors such as the number of pets in your home, local air quality, and how often your HVAC system runs will determine if you need to change them more or less frequently.
