That being said, ozone has a short life and most experts agree that it will revert back to breathable oxygen in about 30 minutes

Q11: Do ozone generators remove cigarette smoke odor?

A: Yes. Ozone will oxidize the over 4000 chemicals that make up cigarette smoke and eliminate the lingering smell.

Cigarette and cigar odors tend to travel to every nook and cranny they can find.
And because of the tar residue that that is part of tobacco smoke, it adheres to everything, especially carpets, drapes, and furniture.

Ozone will travel in a similar path as cigarette  smoke and break down the the molecules that are causing the odor, even the molecules that have glued their self to your furniture.

Q12: Will Ozone kill Mold?

A: An Ozone generator will kill any exposed mold or fungus in the room it is operated inBut similarly to the effect you get with insects is what you get with mold. If you have a problem with mold before you use the ozone generator, you will still have a problem afterwards. It will not do any physical cleanup or identify and fix the original problem.

Q13: Will Ozone Get Rid of the Smell of Cat Urine?

A: The answer is mostly no. Cat urine typically gets deep down into the carpet underneath the floorboards. Ozone is a topical oxidizer and doesn’t get underneath the carpet or inside the walls. There are different oxidizer solutions you can put on cat urine if the problem is not too extreme.

Q14: What Are Ozone Generators Used For?

A. Ozone generators have diverse applications, including:

  • Hotel Rooms: Transforming smoking rooms into non-smoking rooms, restoring rooms with smoke odors, and eliminating cooking smells and harmful germs.
  • Vehicles: Removing persistent cigarette and cigar odors, especially in the cab of cars or trucks, making them smell fresh.

  • Mold Remediation: Clearing mold spores and musky odors from homes after identifying and fixing the source of mold issues.

How To Get The Best Results From A Ozonator?

1.Use the appropriate size generator for your area.

Too small of an ozone machine will not accomplish much and only make the air unbreathable.

Using too large of an ozone generator will increase the amount of time you will need to wait before re-entering the area.

2.  Vacuum the carpets. getting the smell out of the carpets will be much easier if there is not debris and dust all over them.

3. Mop floors and wipe down surfaces.

The same principle as vacuuming the floors. Ozone will have a much easier time getting rid of deep smells if it doesn’t have to get through a film of dirt or grime.

4.  Center the ozone machine in the middle of the room.

5.  Start small. It is always better to use the machine for a shorter time then check the results.

6. You can always run it again and turn it up a little if you need.

The problem with ozone not dissipating the way it should can linked to too much ozone being blasted for too long.

According to some experts, you can get into an arena where VOCs begin to break up and form other types of gases when exposed to heavy ozone too long.

This is not result you’re after. It is much better to start small then have to deal with a problem like that.
