What is the difference between OEM and non-OEM?
“OEM” stands for Original Equipment Manufacturer. OEM products are officially sanctioned or directly manufactured by the same company who made the your air cleaner, air handler, furnace, humidifier, etc. Generic aftermarket products are made to the same specifications as OEM product but are manufactured by a 3rd party. Generic products are typically less expensive than OEM products, and usually exhibit the same quality of construction.
