Works great for cigarette smoke smell in cars!
We recently purchased a used car for my son that had a very potent cigarette smoke smell. I called a car detailing place to ask what to do and they said I could take it to them for their ozone treatment for $125. After doing some research, I found this mini ozone generator and thought I'd give it a try - easier to spend $20 than $125. After the first use the smoke smell was mostly gone. I drove the car the next day (after it had sat in the hot sun) and the smell was back just a little so I ran the ozone again and haven't smelled any trace of smoke since. I highly recommend this product!
