Standard Polyester 1" MERV 5 Standard-Capacity Throw-A-Way Filter

(We recommend a Polyester 1" filter change every month or 12 times per year. For DIRTY environments or most efficient filtration, you may need to change filters more often...do twice-a-month visual checks for the first few months.)

This filter protects your HVAC system. The monobond pinched frame makes the filter very strong. There is no Air Bypass on this filter. Installation is safe and easy - no metal.
