Place one of these high-tech devices in the water of indoor fountains, flower arrangements, terraniums, etc. The Mini-Fogger will produce an evocative dense mist without heat or chemicals. This produces the added benefits of humidifying the air and you can even add a few drops of your favourite essential oil to enhance these benefits. To operate, simply submerge the Mini-Fogger under at least 45mm of water and switch on. Within seconds, a cool fog is produced which lingers at the surface of the water, stirred gently by air currents.The deviceâ€™s housing is solid nickel-plated brass and it operates at a safe low voltage from the supplied plug-in mains adaptor. The membrane is subject to wear; its lifespan depends on a number of factors including water hardness, operating time, etc. Replacement ceramic membranes are available in a kit with a special removal key, (Order Code L41AK).
