Just because you don't operate in damp / humid conditions has nothing to do with the cartridge getting saturated. It has to do with compressed air and the dew point of it.

When you compress air, it raises the dew point (holds more moisture) so the filter pulls that moisture off no matter what the ambient humidity is.

Replace it. It. It's saturated.

thanks for your opinion

Not an opinion at all. Fact. I drove and owned a number of over the road trucks and SOP was dryer cartridge replacement. It's very important to pull out the entrained moisture or it will gum up your works down line.

yes thanks very much and understood but only 29K miles;;; I know my last MH I changed it at 40K miles and after 8 years and the system looked like new that's why iam asking for real life experience and opinions;; what was the mileage on your filters as you were changing them>/?

While no one can tell you for sure if YOUR cartridge needs replacing or not, I can tell you that my owners manual states every 2 to 3 years (no mileage).

thanks and iam very well aware of that;; looking for real world hands on opinion ;;(example) like documented proof the filter fails because of age alone and not water contamination etc
Iam going to change it;; just always looking for a real good reason verses the typical manufactures sell more filter program

I feel sure dougrainer knows the answer, but, I doubt he will answer you. :h
