Formerly known as Germ Guardian, Pure Guardian stays true to its reputation for innovation with its largest-capacity and longest-running humidifiers. The H4500 and H4600 models run for up to 144 hours at a time. They are equipped with Silver Clean Technology, which curbs the growth of mold and mildew on the surface of the tank so that you can spend less time on cleaning and maintenance. These models also feature quiet ultrasonic operation, warm and cool mist options, a low water indicator, and a large 2.4-gallon split tank for easy filling. The H4500 is manual, and the H4600 is digital with an LED display.
Silver Technology for Less Maintenance
Humidifiers relieve respiratory problems and sinus irritation while preventing walls and furniture from cracking. However, they can require daily cleaning to keep mold and mildew out of the water tank. The Pure Guardian H4500 and H4600 humidifiers limit this growth with Silver Clean Technology, which harnesses the natural power of microscopic silver particles to kill bacteria on contact. This extends the life of your humidifier, creates cleaner mist, and simplifies maintenance and cleaning. You never have to buy or clean replacement evaporating pads, filters or wicks.
Packed With High-Quality Features
Ultrasonic technology breaks apart water molecules with a vibrating metal diaphragm to create fine mist. This process allows for near-silent operation. These humidifiers run continually for up to 144 hours—or 6 days—on the low setting (depending on your atmospheric conditions). Each model comes with a 2.4-gallon tank that is split into 2 halves for easier filling in a sink. A helpful low water indicator LED light alerts you if your humidifier needs to be refilled. Both models feature a soft-glow night light.
Easy to Use
Controlling your indoor air humidity is simple with easy-to-understand controls. The H4500 is manually controlled with two adjustable dials—one selects a warm or cool mist, and the other adjusts the amount of humidity and spray level for your room.
The H4600 model features a digital display and touch buttons for more precise control. Press the Spray Control button to disperse the perfect amount of warm or cool moisture into your room. This unit humidifies large or small rooms using 3 spray control settings, including Low, Medium, and High.
The Pure Guardian H4500 and H4600 Humidifiers run for up to 144 hours, or 6 days, and feature Silver Technology for less tank maintenance.
