Hi ! Take off the front and wash out the filter . Also look for any standing water or mold build up . Clean it out . Then you can put a few drops of essential oil on the filter . Good luck !

Check the surrounding area to make sure there is nothing causing the smell near the intake as well.

You can attach an air fresherner to the filter. The link is for a 10 pack (but I know Home Depot sells them individually). https://www.homedepot.com/p/Web-Filter-Fresh-Whole-Home-Air-Freshener-Summer-Assortment-6-Pack-WSUMMER/100656047?cm_mmc=Shopping%7CG%7CBase%7CD26P%7C26-2_AIR_CIRCULATION-ACCES%7CNA%7CPLA%7CAirFIlters%7c71700000052590821%7c58700005054698677%7c92700044209219136&gclid=EAIaIQobChMIwrXCnb_z4wIVlR-tBh3rxwxTEAQYASABEgLtevD_BwE&gclsrc=aw.ds
