Glasfloss ZL 20x25x4 MERV 10 Pleated 4 AC Furnace Air Filters, Box of 4

Engineered with exceptional strength, the Glasfloss ZL MERV 10 filters offer robust filtration capabilities to efficiently tackle the most demanding HVAC challenges. Providing upgraded performance compared to MERV 8 while maintaining a similar pressure drop and airflow, these filters are particularly beneficial for pet owners, as they efficiently remove hair and pet dander from the air for a cleaner living space.

Featuring a moisture-resistant beverage board frame and metal grid that incorporates recycled materials, the 4-inch depth Glasfloss ZL MERV 10 air filters can be used in HVAC systems for commercial and residential properties, school systems, government institutions, and industrial applications. The MERV 10 filter rating, achieved per the ANSI/ASHRAE 52.2 Test Standard, ensures efficient filtration while maintaining low pressure drop and long service life.

The Glasfloss Z-Line Series MERV 10 filter media is laminated to a heavy-duty metal backing, which stabilizes the media during operation. The pleats are formed in a radial configuration, further enhancing the filtration capabilities.

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

It's 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. Manufactured in the USA, the Glasfloss ZL MERV 10 filters are ideal for residential, commercial, school, and industrial filtration applications.

To ensure optimal performance, it is recommended to change the filters at least every 3 months. By adhering to this maintenance schedule, users can enjoy the benefits of cleaner, healthier indoor air quality while maintaining the efficiency of their HVAC systems.
