Product Information

The Honeywell HAC-504 replacement HEPA cool mist humidifier filter reduces contaminants and minerals in your water to prevent airborne pollution and humidifies the air. The ProTec antimicrobial treatment prevents the migration and growth of algae, mold, bacteria and fungus to keep the filter working longer and prevent the spread of disease causing spores.
