Inline Water Filter
Hard water leads to scale accumulation, requiring periodic maintenance. Now you can eliminate more than 95% of scale-forming inorganic minerals such as lime by taking advantage of the scale inhibiting properties of this polyphosphate filter. Disposable filter installs in minutes and generally lasts en entire humidifier season (1,250 gallons / 4,730 litres). Not for use with soft water, or untreated well water. 

Overflow Kit
A ‘must-have’ for attic installations and recommended for all applications with access to a floor drain. Kit includes all necessary fittings and 15 feet of drain hose.

Current Sensing Relay
When the humidifier is powered by a plug-in transformer, this easy to install device saves energy by turning the disc wheel motor off when the furnace fan is not in operation.
