Air filters are extremely critical to your RV generator performance. We’re going to run through the cleaning process now, and if you need to replace it, you can simply stop after step one, and pop-in a new filter, then call it a day.
Locate the fan, which will be directly adjacent to the air filter. You may find a small rectangular plate, which you can usually remove with a Phillips head screwdriver. Standard generators come with either two or four screws.
Ready your cleaning solution. We recommend simple Dawn dishwashing gel, since you’re going to see a fairly nasty mix of debris, dust, and oily grime in that air filter after just one to two months. Soak it for 1-2 minutes, and gently scrub.
Air dry. Don’t pat dry, don’t use a blowdryer - you have to do it properly. Air drying evenly returns the filter to a usable state. You should never put a cleaned air filter back if it has the slightest hint of moisture about it. While the risk is minimal, it’s important to remember that water and electricity don’t mix.
