The Federal Trade Commission ruled in 1996 against a manufacturer of an Ozone generator, ordering them to cease representing their product's ability to "eliminate, remove, clean or clear any indoor air pollutant from a user's environment" [6]

Ozone is a powerful oxidizing agent which could damage rubber and other materials,[7] and ozone reactions with other material present in buildings could lead to increased levels of noxious chemicals such as formaldehyde.[8]"

High-ozone shock treatment - Wikipedia.

In the last year I had two chain smoking couples move out of apartments I own. In one case the painters had to scrub the walls, ceiling and cabinetry thoroughly before applying any paint as the tars from the cigarette smoke had coated all surfaces. I had all painted surfaces primed and then painted with two coats of paint as the drywall is no doubt saturated with smoke products and I wanted them to be sealed inside. I had the ductwork all scrubbed out with brushes and solvent. They had been there 19 years. I also removed all the carpeting and window covering fabric. The husband of the new couple smokes but he goes outside to do so.

The couple in the other apartment was there just three years but they had to have been spending upwards of $1,000 per month on cigarettes at $8/pack. I never saw them without lit cigarettes, ever. Walls scrubbed, a coat of primer followed by two coats of paint, ducts scrubbed out, pretty much the same drill. Turns out they had a pot farm in the bedroom, too.

In another case after a couple I knew passed away their house was to be sold so the executor had a crew come in to conduct an estate sale. A meth pipe was found in a dresser. One of their kids had been smoking meth in the house. The whole house was contaminated and had to be professionally cleaned.

Stench from pet waste is another matter. If urine has soaked into concrete it needs to be treated and likely sealed. Years ago a tenant was breeding small dogs in an apartment I own. It was second storey and had plywood flooring which I had to rip out and replace. Fortunately it was just one corner of a room.

I was talking to the neighbors, and they told me the lady who lived here was a chainsmokers and she had pets but with her declining health she was not able to get the pets out to go to the bathroom

When she passed, an investment company bought the property and basically remodeled it. I heard they had to grind the concrete floor down because of pet urine.

Supposedly before I bought the place they had the ducts cleaned.

I assume the smell that's in the air is because of cigarette smoke. I am thinking about having a company do an a professional ozone shock treatment. It costs $1350.

Based on my research, it looks like this is a pretty effective route to go but I was just wondering if anybody has ever had ozone shock treatment done in their house and what the result was.

There is no way I would pay $1,350 to a contractor unless they guarantee that it will remove the odor. If there is carpet, remove it. If there is left over furniture or curtains, remove them. Paint the walls and ceilings. If that doesn't work, buy another house.

I also run the air handler fan to circulate the ozone throughout the house. Be aware that high ozone levels can be harmful to people and pets which is why I run it when we will be away for a period of time.
