High Efficient Filtration: The HEPA filter captures 99.97% of particles as small as 0.3 microns, including debris, pet fur, mold, pollen, virus, odor, debris mites, etc., making the air around you fresher.

Galvanized Structure: Considering the long-term use, different from others' density plates, we upgrade this HVAC air filter with a water-proof galvanized frame. Also, you don't have to worry about any deformation.

Deep-pleat Filter: Made of solid galvanized frame and fiberglass cotton, the filter structure with the partition plate can achieve high-efficient debris capture and make the air smooth. Create a healthy living environment for you.

Properly Sealed: Size: 24'' x 24'' x 11.5''(610 x 610 x 297 mm). The compact box structure makes the filter material and the outer frame closely combined. Our filter replacement with a large debris capacity has a longer service life.
