I received the six filters in perfect condition and they arrived in short time. Thanks to Keith Specialty, they had the 18" x 19" furnace filters I couldn't find locally. I highly recommend checking out their store. I'm impressed!
Thanks to Keith Specialty I have been able to keep in supply this quality filter. The filter is compatible with the furnace's operation, as well as filters out the junk before it is becomes airborne in the house.
