F-4010: Replacement Ion Exchange Filter for SPT® Humidifier SU-4010 & SU-4010G
Genuine SPT® replacement ion exchange filter for SU-4010 and SU-4010G.
Recommended to be replaced every 6 months.
Ion exchange filter demineralizes and treats water to reduce scale-forming calcium and magnesium from hard water. This prolongs the life of the ultrasonic generator and prevents white dust particles to deposit into the air.
