SafeHome Duo Furnace Filters Customer Q & A

SafeHome Duo Furnace Filters Product Details
Q1: Is a furnace filter the same filter used for return air vents?

A: Not usually. I believe... there are systems where a furnace filter style filter is used on the returns, but the vast majority of air returns have either no filter or a non-woven polyester/electrostatic filter that mainly captures large particles before they can enter the system.
