    Passenger Compartment Air Filter Element

    My wife and I recently purchased a 2011 CTS. The air flow seems to be causing an allergic reaction in my wife. Her nose is burning and she starts
    coughing. The air flow is strong so I am thinking the filter doesn't need changing. This is our first car with an air filtering system. My wife is super
    sensitive to any chemically treated product. Is the 'passenger compartment air filter element' absolutely necessary for the proper operation of the climate control system? I would like to remove it and not use it if possible. We have had 9 previous cars without air filtering and my wife was fine,
    except driving through dusty areas. Then we just cut off outside air temporarily. Any advice would be appreciated.

    The air filter is just a paper filter. No chemicals on it or anything. You just risk dirt and debris going into the cabin and coming into contact with the blower mother and such which in the long run may hurt the motor. But nothing short term, nor do I think it will solve your wife's allergies in the car. Worth a shot to test if they are that bad with her. It's easier to remove that get it in. There's threads and a YouTube video as how to replace it.

    Maybe you have the Mold problem with the hvac cooling coil.

    The only other thing I can think of is maybe they used some sort of deodorizer in the car that is bothering your wife while prepping it for sale.

    Thanks. I have watched that video. Very clear. I suspect I replied to the wrong post.

    You bypass the filter just by using the recirculation function on the hvac with certain settings that only uses the cabin air inside of the car.

    danlorinfw,

    Few things in life are certain, and one of them is that the OEM-spec passenger cabin air filter element is NOT causing your wife's allergic reaction...unless, of course, it's clogged with allergens, in which case it needs to be replaced - not merely removed or bypassed.

    There are many different options/brands for replacing the filter. Check them out and purchase your filter accordingly. Meanwhile, re-read the post by CTSCHICK. That spells it all out.

    My dealer sprays the cabin filter with mold preventative.

    Seems like a waste to me. I live in Florida and it might get humid here, just kinda maybe. I have no mold problems with my car, and I don't see the value other than to charge additional funds to remove/replace your cabin air filter. Meanwhile, this type of spray could be the culprit for the OP.

    Exactly why I mentioned it.

    Re: Passenger Compartment Air Filter Element

    If they used the actual GM stuff it is supposed to be hypo-allergenic and odorless.
    I have 2 bottles of it and use it my self.

    Good to know. Also, I might mention that my dealer charges nothing for the spraying of the filter.

    Hello danlorinfw,

    I am sorry to hear about the difficulties your wife is experiencing with her allergies. As mentioned by several of the forum members, changing out the air filter may help with this concern. If you would like to PM me your VIN, mileage, dealership, and contact information, I would be happy to check your warranty status and get in contact with your dealership to set up an appointment. You can also email me at socialmedia@gm.com with “Attention: Austin” in the subject line.

    Have a great night,

    Austin J.
