Air filter BX2230

[Toyboy]

I've been using Wix exclusively for oil and air. I've been checking prices for the air filter 46449 Ive found that in some listings there is a inner filter to go with the outer. When I first changed mine several years ago, I took the filter with me to make sure I got the right one. My machine only had outer filter and no mention of inner filter was made. Is inner filter that important? My area is grass and not dusty

I have an inner filter on by BX23 and I believe it is a safety measure in the event of an outer filter failure due to perforation.

Thanks, I'll have to look into getting the inner. I wonder how many use the two filter system ???

Both of my tractors have two air filters i.e. an outer and an inner. I'm not convinced that the inner is a safety in the event of a failure of the outer filter. I think its primary function is to further refine the air going into the engine, but it would act as a barrier if the outer filter failed.

I’ve been using two the entire time I have owned it. After every day’s use I pull the outer filter and knock the dust out of it by thumping it on the tire. I learned that when I was a logger.

Yes, it is a safety element and should be in there.
