Elwell Air8 Filter

I am getting a musty smell every time my AC runs … I’ve cleaned the filter and was hoping that would resolve the problem but it hasn’t. I’ve also thoroughly cleaned the box area where the AC sits … Why this musty smell if anyone knows and even though I don’t need to I want to replace the filter if anyone knows where to find one.

I admit I've not poked around the A.C. unit of these trailers, but based on your message, I'm wondering if you cleaned the evaporator? Often times dust and contaminants still get by the filter of an AC unit and the evaporator still needs a little clean now and then.

I used to use Zep foaming coil cleaner on evaporators on refrigeration units. The can says you don't have to rinse it, but I always liked to rinse it. Lay a towel down before you do. While you're in there… might as well clean the condenser too. Keep in mind the direction of the airflow will be the side of the coil you want to focus on.
