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

The air filters feature a moisture-resistant beverage board frame and metal grid that incorporates recycled materials. 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 in media technology to achieve a MERV 10 rating per the ANSI/ASHRAE 52.2 Test Standard, 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 that stabilizes the media during operation. The pleats are formed in a radial configuration, ensuring efficient filtration. The filtration rating of these filters is MERV 10, which is comparable to an MPR rating of 600 to 800 or an FPR rating of 5 to 6.

The filters incorporate 100% synthetic fibers that are electrostatically charged and thermally bonded, ensuring a high dust-holding capacity and long filter service life. The thermally-bonded fibers do not absorb moisture, further enhancing the filter's performance and durability.

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

The nominal size of the Glasfloss ZL MERV 10 filters is 20x25x4, and the actual size is 19-1/2 x 24-1/2 x 3-3/4 inches, with a 4-inch depth. These filters offer comparable airflow to MERV 8 filters, but with improved filtration performance, making them a robust and durable choice for HVAC systems.
