4" Purolator MERV 7 Premium Pleated Filter

(This can ONLY be used if you have a Media Air Cleaner of some type.)

(All pricing INCLUDES taxes and UPS Standard Ground shipping.)

(We recommend a MERV 7 4" 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.)
