Variable sonic waves, at the right frequency and with a correct waveform, guarantee an excellent repellent effect, especially for mosquitoes. Being slightly audible, it is possible to vary the intensity up to 3 levels according to your liking.

When used at home, especially in the bedroom, it is recommended to set the device to maximum intensity at bedtime and to minimum once in bed.

DOUBLE DEFENSE MOSQUITO REPELLENT: FREE TO CHOOSE YOUR PROTECTION!
Does the slight hiss of sonic mode bother you? Use the Low Sonic or Ultrasonic Mode Option

Are you outdoors? Use High Sonic Mode

The slightly audible sonic emissions are effective against mosquitoes because they reproduce the call of the male mosquito by driving away the female, the one that bites, in search of blood for the eggs. They have a greater repellent effect than ultrasonic ones, but in some subjects they can be audible and therefore generate discomfort.

The ultrasonic mode is not audible to the human ear, but it has a lower effectiveness and range than the sonic one.

From today, with COLPHARMA DOUBLE Defense you can decide which of the 2 modes you prefer, to best meet your needs!

COLPHARMA DOUBLE Defense uses 2 combined repellent technologies: sonic emissions (2 intensity levels) or alternatively ultrasonic.
