This new air cleaning system is great. I bought one for my kitchen and one for my basement. Those nasty cat litter boxes in the basement really needed something to help with air smell. These systems are very simple to operate and work wonders. It uses moisture inside a small plastic container and a small electric unit that pulls in air from the top forcing it through the funnel system into the water below. You can add essential oils to the water to give off a nice scent into the room. The unit already comes with 4 bottles. (lavendar, citrus, lime and vanilla). My favoite is the lime and citrus, the smell makes the room smell clean and fresh. Besides it adds moisture back into the air which is great in the summer months.
Overall this product is well worth the money, about $50 each. You can also buy the scents separate in case you run out.
