MITELESS PORTABLE - Ultrasonic repellent device for repelling dust mites, one of the main causes of respiratory allergies. Contains no chemicals or fragrances, but emits pulsating ultrasonic pulses at 40 kHz, which are not harmful or unpleasant to humans or animals. Constant use of the device reduces the concentration of dust mites in the room, thus reducing respiratory allergy symptoms. The device can be conveniently attached to the child's bed or in its immediate vicinity, or placed in the car. After activation, the device works for one year and the operating range is 3 m. Usage: Remove the protective plastic tape (PULL) and press the button once. The light blinks 4 times to indicate that the device is on. The battery is not replaceable, the duration of operation is 12 months. To check if the device is still working, press the button and see if the red LED light is still flashing. Moisture cannot damage the device (drop-resistant), however the device itself is not waterproof - direct contact with water should be avoided or a wet device should be dried, e.g. with a hair dryer. Protect from children. The effectiveness of the device has been tested at the University of Camerino, Italy. Made in: Italy.
