Sources Of Black Particles
Black particlesfrom air conditioners often come from mold and mildew growth. These fungi grow in damp areas inside the AC, especially on coils and drip pans. They release tiny black spores into the air, which you see as dust.
Dust and dirt accumulationis another source. Over time, dust builds up on AC parts. This dust mixes with moisture and forms black grime. When the AC runs, it blows this grime out.
Degraded air filter materialcan also cause black particles. Air filters catch dust and dirt. If filters get old or damaged, small pieces break off. These bits come out with the airflow and look like black dust.
