High Humidity and Moisture Accumulation<\/span><\/h3>\n

Dust and Organic Materials<\/span><\/h3>\n

Dust, pollen, and other airborne particles enter the AC and settle on the coils or inside the filter. Over time, this build-up combines with moisture, creating the perfect surface for mold spores to grow and spread.<\/span><\/p>\n
