Glasfloss ZL 20x25x4 MERV 10 Pleated 4 AC Furnace Air Filters, Box of 4, 19-1/2 x 24-1/2 x 3-3/4 Actual Size

Engineered with exceptional strength, the Glasfloss ZL MERV 10 filters offer robust filtration capabilities that efficiently tackle the most demanding HVAC challenges. Providing upgraded performance compared to MERV 8 filters, these air filters maintain a similar pressure drop and airflow. Beneficial for pet owners, Glasfloss filters effectively remove hair and pet dander from the air, contributing to a cleaner living space.

Featuring a moisture-resistant beverage board frame and a metal grid that incorporates recycled materials, these air filters are designed for premium performance. The 4-inch depth Glasfloss ZL MERV 10 air filter can be used in HVAC systems for commercial and residential properties, school systems, government institutions, and industrial applications.

The MERV 10 filter incorporates the latest media technology to achieve a MERV 10 rating per the ANSI/ASHRAE 52.2 Test Standard, while maintaining low pressure drop and a long service life. The Glasfloss Z-Line Series MERV 10 filter media is laminated to a heavy-duty metal backing that stabilizes the media during operation, and the pleats are formed in a radial configuration.

With a filtration rating of MERV 10, the Glasfloss ZL MERV 10 filters are comparable to MPR ratings of 600 to 800, or FPR ratings of 5 to 6. The filters incorporate 100% synthetic fibers that are electrostatically charged, thermally bonded, and manufactured in an engineered gradient structure. The thermally-bonded fibers do not absorb moisture, and the engineered grading structure media supports high dust-holding capacity and long filter service life.

It is important to note that these filters do not replace 5-inch or 4-3/8-inch depth filters. Users should check the actual filter size needed before making a purchase. The Glasfloss ZL MERV 10 filters are made in the USA and are ideal for residential, commercial, school, and industrial filtration applications.

For optimal performance, it is recommended to change these filters at least every 3 months. Adhering to this maintenance schedule will ensure the filters continue to effectively remove hair, pet dander, and other airborne contaminants, providing a cleaner and healthier indoor environment for occupants.
