Glasfloss 20x25x4 MERV 10 (FPR 5-6) 4 Pleated Air Filters Box of 3

The Glasfloss ZL MERV 10 filters are engineered with exceptional strength, providing robust filtration capabilities to efficiently tackle the most demanding HVAC challenges. Compared to MERV 8 filters, these MERV 10 filters offer upgraded performance 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, resulting in a cleaner living space.

The air filters feature a moisture-resistant beverage board frame and metal grid that incorporate recycled materials. With a 4-inch depth, the 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 is achieved through the latest in media technology, as 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. The pleats are formed in a radial configuration, providing 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 5-6.

The filters incorporate 100% synthetic fibers that are electrostatically charged and thermally bonded, creating an engineered gradient structure. This design ensures high dust-holding capacity and a long filter service life, with the added benefit that the thermally-bonded fibers do not absorb moisture.

It's important to note that these Glasfloss ZL MERV 10 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. These filters are made in the USA and are ideal for residential, commercial, school, healthcare, and industrial filtration applications.

For optimal performance, it is recommended to change the filters at least every 3 months. The durable and long-lasting frame of these filters ensures they won't buckle, providing reliable and efficient filtration for the duration of their service life.
