The filter dimensions are 20 inches x 20 inches x 4 inches, providing an ample filtration area. This filter is constructed by covering a layer of metal mesh over the synthetic fiber, which is then folded into a compact design.

The 310 furnace air filter has a MERV 11 rating, making it suitable for use in homes, schools, hospitals, and offices. MERV, or Minimum Efficiency Reporting Value, is a scale that measures a filter's ability to capture particles of different sizes. A MERV 11 rating indicates that the filter can effectively trap a wide range of airborne contaminants, including pollen, dust mites, mold spores, and certain bacteria.

The filtration material used in the 310 air filter is a soft and lightweight synthetic fiber. This material allows for smooth air flow, ensuring efficient filtration without creating excessive resistance. The combination of the metal mesh and the synthetic fiber provides a durable and effective filtration system that can help improve indoor air quality.

Compatible with a variety of AprilAire whole house air purifier models, the 310 replacement furnace air filter is a versatile solution for maintaining a clean and healthy indoor environment.

The vertical contraction feature of the filter also helps to retain its shape, preventing deformation and ensuring consistent performance over time.

Overall, the 310 replacement furnace air filter is a high-quality and reliable solution for improving indoor air quality in a variety of settings. Its MERV 11 rating, compatible design, and durable construction make it an excellent choice for homeowners, school administrators, hospital staff, and office managers who prioritize clean and healthy air for their occupants.
