CREWORKSOzone Generator, 5000 mg/h High Capacity Ozone Machine for Car Home Smoke Pet Odor Removal, Commercial Ozone Odor Eliminator Air Purifier with Timer Display for 3200 sq ft Room, Black

I bought this to control mold in a basement. I let it run in a bedroom for 30 minutes and did not enter the room for another 24 hours. It absolutely killed all mold in the room. Ozone (O3) is heaver than (O2). This works to your advantage with carpet. Note: The built in temp and humidity gauge is accurate. I ran a dehumidifier at the same time to get the humidity level from 80% to 55%. I'm not sure if this can cover 300 square meters but it works great in a single room.

So I forgot and left a gallon of milk in the trunk of my car for nearly a week after getting groceries. As you can imagine the smell was horrific. Luckily it didn't burst open from the summer heat but the jug was swollen and gassing off. Air fresheners and leaving the trunk open to air out didn't help much at all. So I buy this to get rid of the smell and it worked. I placed it in the car and turned the timer up to max time and let it run with all doors and windows closed. Additionally ran it for 15 minutes with ac on recirculating. Had to do 2 treatments like this within 3 days. Smell is gone. Very pleased with the results. Also I let the back seat down so the machine could do the whole inside cabin at once.

Sometimes my 3 cats are mean and sometimes smells just linger no matter what you do. Which lead me to this machine and wanting to give it a try. I noticed a change almost instantly. It was able to take smells away that I didn't even realize were there. It's fast and efficient and great to have around when needed.Definitely, recommend following the instructions and taking precautions when using it.

I bought this Ozone generator in hopes of freshening up the musty air in my 50+ year old house. I was amazed with it's first use when I returned home after running it for a hour to find the air in my house smelling like the fresh air after a heavy rain. All the cooking smell of bacon were gone and even it even clears out the smell of fish and seafood after cooking as well. I'm well pleased with it and definitely recommend it.

VERY WELL MADE AND EFFICIENT GENERATOR.VERY PLEASED.

Purchased a home from a smoker. I had to run it 2-3 times in each room for at least an hour but the entire home is SMOKE FREE. I ask guests all the time if they can smell it and they say no. Very nice.

Worked good, got rid of the smell

This destroyed the smoke smell in my car. I really enjoy it and I recommend it to other.
