The pureguardian 120-Hour Ultrasonic Humidifiers can fight mildew and mold in your tank with Silver Clean technology.

Three year warranty.  The pureguardian H4500 and H4600 ultrasonic humidifiers can run up to 120 hours and have a 2.4 gallon water tank.  You can choose from a cool or warm mist.  The special indicator light tells you when you need to refill the water tank.  The machine is ultra quiet and has a night light you can turn on and off.

The only difference between these two humidifiers is that the H4600 has digital controls with programmable run features.

The pureguardian humidifier includes a metal diaphragm that vibrates at an ultrasonic frequency that creates water droplets that are sent into the room to achieve the humidity level you want.

There are no filters, wicks or pads to replace and the variable spray works in large or small rooms.
