andrea-air-purifier-vs-normal-plant

I came across this ANDREA Air Purifier on inhabitat and couldn't quite get my head around it. See the video making some astonishing claims here.

I can't help but think this is another pointless design with dubious benefits; wrapped up in a nice pseudo-science snake-oil sales pitch (any pitch that uses the word "detoxify" is suspect in my books.) This object will cost more resources to manufacture, ship and operate than a common old pot plant. And it will create significantly more waste.

What if I just grew a bunch of pot plants and stuck a desk fan next to them, and add a couple of trays of water? Less tidy for sure.

Can anyone please explain this to me? This could be an elaborate hoax of course.
