The Sonic Guard Miteless Ultrasonic Protection Against Dust Mites is a revolutionary way to fight back and prevent allergies. It contains no chemicals or fragrances leaving it environmentally friendly. This device emits a series of ultrasonic pulses (40,000 hertz) that are unnoticeable to humans, dogs, and wild animals, but disturbs dust mites. It reduces the concentration of mites in the environment in which it is installed. In 2012, the University of Camerino in Italy confirmed the effectiveness of this product.
The Sonic Guard Miteless Protection Against Dust Mites is portable and good and last up to 6-12 months. While it is not waterproof, it is water resistant. Should it get wet, dry it immediately to keep it effective. To operate, easily pull the tab and push the button to turn the device on or off. There will be 4 short green flashes when you turn it on, and 1 long flash when you turn it off.
Great for reducing dust allergies in the car, closet, or traveling.
