Zielonka Air Freshener XL Including Rubber Bowl Black Colour and Dimension 17.5 x 17.5 x 3.2 cm, One Size

Absolutely useless didn't help a bit. I should have known better and not wasted my time.

I'm rather surprised that these work. I hoped they would when I took the plunge and bought two, and I don't understand how they work, but they do. So, I'm surprised and pleased. There's a smoker in the house, and the living room always had an accumulated smell of smoke, but no more. They don't so much absorb it immediately as, in no time at all after the cigarette has been put out, the smell just disappears. As I said, I don't know how it works (and I really don't much care) I'm just glad it does. I can't help but think that, if it works on cigarette smoke, it should work on just about any other smell. Just one thing to point out....if you spray freshener it will gobble that up too!

Just place metal object in water and it works like a catalytic converter?! Very scientific piece of kit for the home.
