Vicks Comforting VapoPads are a refill of essential oils for your Vicks Comforting Vapours Plug-In, which helps to reduce the discomfort of coughs and colds. The Plug-In offers the safe signature of the Vicks natural scent. With its well-known protective Vicks shield form, the Comforting Vapours Plug-In is easy to use. Simply insert a Vicks scented VapoPad into the Comforting Vapours Plug-In and plug it into a power socket. The heat activates the natural essential oils and releases their vapours into the air. A single scent pad will give up to 8 hours of comfort and wellbeing. The Plug-In also glows softly, becoming a nightlight to help ease the path to a good night's sleep. Each pad contains essential oils, and the 7 Vicks refill pads per pack fit all Vicks Waterless Vaporisers and Vicks Humidifiers that use scent pads.
