4x5 Reviewed by 4x5 on . The "Z" Machine * Ozone Generator * Hello peoples. After using a homemade carbon scrubber, and not being satisfied, I made a second scrubber composed of carbon, cat litter, bounce sheets, and a whole arsenal of other smelly crap. It still didn't seem to get rid of the lovely plant smell. ( sucks we have to hide it eh? ) Well, I refuse to spend $600 + for an ozone generator, so I built one. Using a 5000 volt neon sign transformer, a cat litter box, aluminum foil, and other little bits of stuff, I created the "Z" Machine. Rating: 5
