I can think of three reasons off the top of my head

1) It's $20 cheaper
2) No assembly whatsoever
3) It's three inches in diameter, not a five gallon bucket.
Shermania Reviewed by Shermania on . Vaportek odor control... I was doing some researching on some easy and inexpensive ways deodorize my grow. I thought about buying a Carbon Scrubber but those can be expensive, and loud, and hard to set up, if your a technonincumpoop like me, so I checked out some threads. Vaportek is a company that makes deodorizers for disasters, fires, hospitals, crime scenes(dead bodies, yuk!) Most of the people who talk about them talk about the optimum 4000 air treatment system that goes for in between $150 and $250 Rating: 5
