The HC22E1003 Enviracaire Elite Humidifier Pad is coated with the Agion Antimicrobial Compound. This agent prevents the surface growth and migration of bacteria, mold, fungus and algae on the humidifier pad.
To prolong the life of your humidifier, replace the pad (water panel) at least once per year. The frequency will depend on the conditions of your water. Refer to the Owner's Guide for complete instructions.
And remember: Your old pad is recyclable. After removing it from the humidifier, just rinse off the powder from the pad and recycle it with aluminum recyclables.
