The EcoGecko Magic Ball is a powerful workhorse for neutralizing unpleasant odors in your space. Simply fill the bowl with tap water, add a few drops of the included Lavender oil and turn on the freshness. The unit has a fan system that sucks the air from the room into the water. The air is pushed through the aroma oil scented water, particles are trapped in the water and pleasantly scented air is released back into your room. The gently swishing water creates soothing white noise for a peaceful and restful environment. LED Lights give the unit a whimsical feel. You chose multi-color, chasing, alternating color, solid or no color at all.
