2" 3M Filtrete Commercial MERV 11 Media Filter

(This 3M Filtrete Filtration system can be used with all standard type furnace and air handlers that can house a 2" filter system.)

(We recommend 3M Filtrete 2" filter change at least twice per year - September & March. For DIRTY environments or most efficient filtration, you may need to change filters more often...do monthly visual checks for the first few months.)

The 3M 2" Filtrete Commercial MERV 11 media replacement performs equal to or better than original equipment performance. It delivers up to 70% efficiency on 1 micron and larger particles, effectively reducing dust accumulation on household furniture. The unique face board design lowers initial static pressure, which keeps your system's blowers running at peak efficiency.
