Keep your home smelling fresh with our Electric Plug In Air Freshener Twin Refill. Packed with cool, fresh and invigorating fragrance notes this starter kit will transform your surroundings by adding a layer of freshness while neutralising odours. With a twin refill pack the fragrance lasts up to 60 days based on 8 hours of daily usage. Directions for use: Remove the plastic cap from the fragrance bottle. Please retain the cap for future use. Firmly insert the fragrance bottle in an upright position into the underside of the plug-in unit until you hear a click. Do not use excessive force when inserting a fragrance bottle as this may cause the wick to snap. Plug the plug-in unit into the socket. To remove the fragrance bottle, switch off the plug socket and remove the plug-in unit. Ensure the plug-in unit is upright and slide the fragrance bottle out from the underside of the plug-in unit. Replace the cap on the fragrance bottle and keep it in an upright position in a cool, dry area away from direct sunlight.
