It's just an agitator that swirls water with perfume inside. It's basically a perfume dispenser... a freaking expensive one.
I can't think of a use for a perfume dispenser in the home. Those cheap Ambi-pur thing isn't doing well at home - they unleash a cocktail of solvents to be inhaled. I avoided all these stuff at home. I'm not smelling anything at home - either I get the natural, or I'd use a activated carbon.
Well, FYI, activated carbon will ABSORB all fragrances, chemicals and particles that pass through it. That's what it does.
Hmm. Besides the magic lamps, I've seen another one, a popular one. It's starting with an "H" and ends with the "life". And these supplements, are on times, dangerous. My cousin blew up a lot of money on that for a short term marketing of these products.
