Why Upgrade to MERV 16?
MERV 16 is among the highest filtration ratings available for residential-style media filters. It provides hospital-grade particle capture efficiency, significantly reducing airborne allergens and contaminants that lower-rated filters allow to pass through. Replacing your filter on schedule with a genuine Lennox X6672 ensures your system continues to deliver clean, healthy air while protecting your HVAC equipment from damaging particulate buildup.
