Glasfloss 20x25x4 - MERV 13 - Pack of 2 - Pleated Air Filter

The Glasfloss 20x25x4 furnace air filter boasts a MERV 13 rating, featuring an extended surface pleated media that delivers low pressure drop and high energy efficiency, without absorbing moisture. Rigorously tested to meet ASHRAE Standard 52.2 for MERV rating and classified per UL Standard 900 for flammability requirements, Glasfloss filters are designed to provide reliable performance and safety.

The MERV 13 rating of the Glasfloss filter ensures efficient filtration, capturing a wide range of airborne particles, including dust, pollen, and pet dander, while maintaining a low pressure drop. This allows the HVAC system to operate at optimal efficiency, reducing energy consumption and costs.

The extended surface pleated media design of the Glasfloss filter contributes to its impressive performance. By increasing the surface area for filtration, the media can capture more contaminants without significantly impeding airflow. This results in a longer filter lifespan and reduced maintenance requirements, as the filter does not need to be changed as frequently.

Importantly, the Glasfloss filter is engineered to withstand high temperatures, with a maximum operating temperature range of 180°F. This makes it suitable for use in a variety of HVAC systems, including furnaces, air conditioners, and heat pumps, without risk of degradation or failure.

The rigorous testing and classification of the Glasfloss filter further underscores its quality and reliability. The filter has been tested to the ASHRAE Standard 52.2, which measures the filter's ability to capture and retain airborne particles of different sizes. By achieving a MERV 13 rating, the Glasfloss filter demonstrates its exceptional performance in trapping a wide range of contaminants, ensuring cleaner and healthier indoor air quality.

Additionally, the filter's classification per UL Standard 900 for flammability requirements provides peace of mind, as it indicates that the filter meets strict safety standards and is not a fire hazard in the event of a heating system malfunction.

In conclusion, the Glasfloss 20x25x4 furnace air filter is a high-quality, efficient, and safe solution for maintaining indoor air quality. Its MERV 13 rating, extended surface pleated media, and temperature resistance make it a reliable choice for homeowners and HVAC professionals alike, ensuring optimal system performance and energy efficiency while safeguarding the health and well-being of building occupants.
