Cabin Air Filter DK 45 Recirculation Mode

[wxtrendsguy]

Is there another filter other than the two useless little air filters above the driver door which do little more than remove dust in the fresh air intake?

I am referring to the time when the cabin air lever is turned to the recirculation mode. When I am out spraying I can tell after a while that the level of spray contaminant in the air inside the tractor cabin is climbing, I did not notice that a few years ago but definitely more so this year so I figure there must be a filter somewhere that needs changing.

Any help?

Ok finally dug out my owners manual...yea yea I know but why take the easy route. Anyway turns out the DK45 tractor cab is and I quote "not designed for spraying chemicals and cannot block polluted outside air from entering"

So in lieu of that revelation and not wanting to go to jail due to strangling the sales guy is there anyway to continue to use this tractor safely?
