The cordless device uses an odourless and biodegradable Pyrethrum extract to repel mosquitoes. Easy-to-replace cartridges dispense this agent in a metered manner and distribute it in the room by evaporation through a built-in fan. This well-designed mosquito repellent in subtle white is quiet in operation and equipped with a practical Bluetooth function for control via an app. It is also possible to programme a timer.
