Cool and Warm Mist Humidifiers

Guardian Technologies humidifiers are all Ultrasonic, with Silver Clean Technology 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!

Ultrasonic Technology

They produce a warm or cool mist by using a metal diaphragm vibrating at high frequency. The sound vibrations propel moisture which is almost immediately absorbed into the air. Because this type of humidifier does not use a fan, it is very quiet when operating making it a great sleep aid.

A Better Home Environment

The ideal humidity level in your home is around 35% to 45%; however, when you've got your thermostat working double time to keep you warm humidity levels can fall to single figures – not so satisfying for your skin. Fortunately, you can avoid this with the use of PureGuardian ultrasonic humidifiers in your home or office.

Aromatherapy Tray Option

Select Pure Guardian humidifiers include an optional aromatherapy tray so a few drops of essential oil can be added to create a relaxing atmosphere.

Could use some redesign for user health and easy of use
3 Stars
Could use some redesign for user health and easy of use
Pros- Controls and parts are easy to understand- Extension tube provides separation between mist outlet and sensing portCons- When needing to refill the tank, you will always get water everywhere around the unit from condensation in the exhaust port through the tank and extension tube. Can't avoid it.....- No turning off the display at night- Humidity reading was underreporting by 7% when comparing it to a Vaisala Nist traceable reference probe, needs a user adjustable calibration offset. This can pose quite a problem if humidity levels go above 50% in a room, you will start getting mold growth. So this is very IMPORTANT. On that note, you should not be able to set it above this value for the point of mold. 35-50% should be a limited safety range.- Can't set a value below 40%, which at current is at odds with the above.- Warm Mist setting doesn't do much other than waste electricity, doesn't seem to affect rate of humidification in a space one way or another. Makes the reservoir basically a bacterial incubator without a bactericide added for ever fill.Final ThoughtsIt's an OK unit but needs some addressing in a few areas and some functions trimmed that don't add value.Another note on those thinking of non-demineralized water: As an experiment I want to show you what happens when using tap water in any amount. Tank was 2/3 full of distilled and the rest filled with tap. The attached photo in my office space shows all those dissolved compounds get airborne as extra fine particles you get to breath in. If you know anything about pm2.5 size particulates you would do well to not do this and stick to RO or distilled for anything other than a wick type humidifier. It's not worth the mess or the impact on your indoor air quality. Do yourself a favor and buy a tabletop distiller or two.
