Overview

Keep your Generac standby generator breathing easy with the HUSWELL 0J8478/0J8478S air filter.

Specifically crafted for air-cooled Generac units, this filter targets the 14-22 kW range that characterizes many residential and small-business standby systems. It’s built to work with the V-Twin 990cc and 999cc engines commonly found in post-2013 models, making it a practical option for many Generac owners who want a reliable, ready-to-install replacement.
