Why Upgrade to a MERV 11 Media Filter?
Compared to standard 1-inch filters, the deep-media design of the Lennox X0585 provides a significantly larger filtration surface area, resulting in lower airflow resistance, longer service life, and more effective removal of fine particles. Regular filter replacement ensures your system operates at peak efficiency while maintaining optimal indoor air quality.
