Description
Keep clean air flowing to your engine with this Generac 0G5894 air filter replacement two-pack from UGP. These aftermarket filters are designed to replace Generac 0G5894 in select pre-2013, 20kW air-cooled home standby generators equipped with 999cc V-twin engines.

Why Replace the Generac 0G5894 Air Filter on a Standby Generator?
Your generator’s engine needs a steady supply of clean air. The filter media helps capture dust, dirt, and other airborne particles before they enter the engine. Replacing a clogged or damaged standby generator air filter can help maintain proper combustion, reduce unnecessary engine strain, and support consistent generator performance.
Inspect the air filter regularly and replace it when dirty, damaged, or at the interval specified in the generator owner’s manual. Generators operating in dusty conditions may require more frequent inspection and replacement.
Two-Pack of UGP Replacement Air Filters
This set includes two UGP replacement air filters. The second filter gives you an additional filter for a future service interval, spare inventory, or maintenance of multiple compatible generators.
Each UGP Generac 0G5894 air filter helps block dirt and airborne debris while supporting proper engine airflow and dependable generator operation. It works as a 20kW generator air filter for the compatible models listed below.
