Foam air filter disintegrating, clogging carb, alternatives?

I have an older yamaha ef2800i generator that I keep in storage for power outages and a couple years ago, it ran very poorly. I discovered the foam filter disintegrated and tiny particularly fed into the carb. Big mess. Decided the filter was very old, original, so hard to fault it. I ordered a new oem foam filter and now, 2 years later, it has done the same thing. I looked online for a paper alternative but nothing popped up so I ordered another oem foam filter but I’m very hesitant since carb rebuilds on this model take some work.

I know I could just replace the filter once a year and that may be the answer but for a gen that is used once every 2-3 years, I just don’t think about it and prefer to find a different option.

Any ideas? I don’t have this problem w my Honda’s

    I would simply put it on the To Do list for when you de-winterize each year.


    Yeah, this may be what I need to do, just wondered if there were some other ideas or whether others have seen this kind of thing. It’s amazing to see the degree of disintegration, one heck of a powdery mess.

    Is the foam filter supposed to be oiled? Have a look see in the manual...


    Yes, oiled.
  • The manual says to clean or replace every 3 months or 50 hr and yes, oil it after cleaning.
