Ozone generator use in a townhouse?

[Christian Bors]

Hello,

I have a property under contract that has a strong odor smell.  I have dealt with odor smell in the past with success.  On this particular property, the odor is in the master bedroom on the third floor of a town house.  I was thinking about removing the subfloor (or at least a section of it) and installing new subflooring.  However, the subfloor runs underneath the walls.  So even if I would like to remove all of it, its not possible.  My plan of attack was to roll 2 layers of Kilz Original and then place an ozone generator.  However, I am not too familiar with ozone generators and the harm they can cause.  I recently purchased a model, however it is still in the mail so I have not read the instruct manual.

I have read it is "ok" to run the ozone generator in a basement, seal off the basement, and stay upstairs since the gases produced weigh heavier then air.  Can you run an ozone generator in a townhouse, seal off the master bedroom, and not put your neighbors at risk?  I had a restoration company look at the situation and they quoted me using an ozone generator to kill the smell.  They were not concerned.  Since I do not know how safe theses items are, I wanted to see if anyone has experience using an ozone in a townhouse.  The last thing I would want is Fluffy, the neighbor's dog, to take a very long nap.  Any advice?
