Ultrasonic Mosquito Repellent

Friend is an advanced electronic instrument that protects you without being noticed and leaving the air that you breath free from any odor.
Friend sets you free from mosquitoes with imperceptible ultrasounds.
Friend diffuses ultrasounds at a wide range that cannot be audible for humans.
The working frequency varies automatically from 22 to 28 KHz to avoid an addicting phenomenon and disturbing mosquitoes of different species.
With a very fast wave sequence FRIEND diffuses ultrasound waves of different frequencies to cover the whole sensitivity arc of mosquitoes.
You cannot hear it; it does not disturb or bother you.
The ultrasounds stun the mosquitoes that move away from the place where Friend is working, or they have troubles in flying and they cannot sting anymore.
Friend does not diffuse any substance in the air.
With Friend you will not need to ventilate the room before entering it. You can keep it on as long as you like, even when you are in the room.
For this reason, Friend is the most environment-friendly solution to get protected from mosquitoes. It is a true friend for everybody and above all for children.
Friend can be found in two versions:
EcoFriend
For your living room, your kitchen, and your bedroom.
BabyFriend, with a green night-light.
BabyFriend is even a greater friend for children because it diffuses a relaxing and reassuring green night-light. If you keep it on day and night, it protects your children against mosquitoes and it calms them down while they are asleep.
