OdorStop OS3500UV Professional Grade Ozone Generator Ionizer for Areas of 3500 sq ft and above

I use this for work as I remodel rental units. Had a house where there was extreme smell of dog waste in the basement that had permeated in the whole house. The basement floors have been painted twice in the whole house has been repainted, but the smell was still very strong. Ran this ozone machine for a couple days, and it completely eliminated the odors. Easy to transport and move around. I really like that it has timers and a nonstop run function for when you need it to run for more than a day. Definitely run out of the room when you turn it on. If you’re trying to remove oders from a whole house, don’t forget to open all the closet and cabinet doors and have your furnace on constant fan mode to disperse and enable the ozone get everywhere.

This thing does what it claims to do. Well worth the price. Highly recommended.

I purchased a house with such a terrible embedded smoke smell I could notice the smell outside as I walked towards the house on the sidewalk. Disgusting. I was really skeptical that anything would ever take the smell away. Enter the ozone machine. I set it on max for two full cycles leaving the house unoccupied. When I returned the smell was 100% gone. One of the few products I have purchased that performed BETTER than advertised. I even purchased extra ceramic plates, but didn’t even need them. Recommend this product highly!

This truly works, just remember, you must air out the house when you're done very important.

Stopped producing Ozone on 08-07-26. It lasted a little over year. Alot of money for 1 yr operation. Buyer beware

Busts the funk, be it produced by dog, cat or both. Also ends that horrible mold and mildew smell. We've used in our apartment buildings and in our homes. Renews the breathing space very well. Only problem is price: should be sold, delivered for under $300.

Not sure how to rate SENT? I can't stand the smell these things make and you are NOT suppose to breath it either. The MOST IMPORTANT thing is it DOES A VERY GOOD JOB at KILLING ODORS as it was designed to do. I guess it is possible to turn down the settings enough to lower the "SENT".... but in my opinion , it is best used as a TREATMENT to KILL ODORS....and it WORKS GREAT! I ran it in my stinky work truck with ac on and it killed the FUNK completely. I "TREATED" my travel trailer with AC on to get rid of the MUSTY SMELLS and it did a wonderful job. I am VERY IMPRESSED! It does the job and has the capacity to do larger areas too.

I have a rental that was smoked in and was holding odors. I had heard of ozone generators used for such and that it really worked. After the house was emptied and any materials that held odors removed, I ran the generator 3 times for 4 to 6 hours moving it throughout the house. I was amazed at the difference in the air quality. While there is still SOME odor detected, I believe when the next step of primer and paint is completed, it will be gone. I would purchase it again.
