Uses Silver Clean Technology

The condensation that sets on the humidifier overtime can cause mold, mildew or bacterial contamination. Silver Clean™ Technology is a form of micro-silver crystal technology that has been embedded in the water tanks of Guardian TechnologiesTM humidifiers. It's used as a fungi-static agent in order to fight the growth of mold and mildew on the surface of the tank.

Won't Expel Impurities with Proper Water Treatment

Unlike the humidifiers that boil water, the water droplets that are produced by an ultrasonic humidifier contain any impurities that are in the water tank which include minerals contained in hard water. If you use tap water in an ultrasonic humidifier, it may produce a white dust that can settle on nearby objects and furniture. If you use distilled water, white dust is not produced. If you choose to use tap water, you can use our FLTDC Humidifier Demineralization Filter to prevent white dust from being created.

Mist Immediately Absorbed into Air

The water molecules that are produced by ultrasonic technology are extremely small – about one micron in diameter. As a result, the mist is immediately absorbed into the air. This allows the air in the room to reach the desired humidification level more quickly and efficiently.

Ultra Quiet Operation

Many humidifiers operate with a large fan that can produce a noisy humming sound. This can disrupt your sleep or living space. Guardian TechnologiesTM PureGuardian® humidifiers use a metal diaphragm vibrating at an ultrasonic frequency to create water droplets that are expelled out into the room to help maintain the desired humidity level. An ultrasonic humidifier is virtually silent when operating.

How to Choose a Guardian TechnologiesTM Humidifier

Guardian Technologies'TM humidifiers are all Ultrasonic, with Silver Clean Technology to fight mold and mildew on the growth of the humidifier water tank and reduce the chance of impurities being expelled into your indoor air. They're also all designed for ultra quiet operation to help avoid sleep disruption. The only thing left to do is decide whether you want Warm or Cool Mist. They both provide the same comfort, and to select your desired size!

Warm vs. Cool Mist

Both warm and cool mist humidifiers emit a mist that helps you to breathe easier in your indoor environment. While they produce different temperatures of mist, they both add moisture to the air. Warm Mist humidifiers can help to make your bedroom or office feel warmer. This is especially ideal for families living in a region with harsh, cold winters. The combination of moisture and heat from a warm mist humidifier can allow you to turn down the dial on the heating system at night, which can ultimately help make cold nights more comfortable. Cool Mist humidifiers emit a room temperature mist.
