Glasfloss MR-11 Pleat Filter

A MERV 11 rating indicates that these filters are highly effective at capturing smaller particles, including dust, pollen, pet dander, and smoke. They provide a significant upgrade over standard fiberglass filters, making them a great choice for households with allergy sufferers or pets.

For optimal HVAC efficiency and air quality, it is recommended to replace these filters every 90 days. However, if you have pets or live in an area with high dust levels, you may need to check and replace them more frequently to prevent airflow restriction.

No, these are disposable, single-use filters. Once they have reached their capacity for trapping particles, they should be discarded and replaced with a fresh filter to maintain your system's performance.

These filters have nominal dimensions of 18 x 24 x 2 inches. Before purchasing, verify your current filter's dimensions or check your HVAC system's manual to ensure these measurements match your specific unit's requirements.

The pleated design increases the surface area of the filter, which allows for better particle capture without significantly restricting airflow compared to flat filters. While it provides higher filtration, it is designed to work within the standard operating parameters of most residential HVAC systems.
