O-888 Industrial Ozone Generator 20,000 mg/h - O3 Machine Air Ionizer Odor Remover Eliminator for Rooms, Smoke, Cars, and Pets

We have an old commercial building with a damp basement from when a heavy rain leaks in through the ground, so the odor is generally musty. We run multiple dehumidifiers which greatly helps on the moisture content, but not the smell. I originally bought 2 of these units but after using one for a couple of overnight cleanings, I returned the second one because one unit does the job. I set the unit to run for an hour or two in a basement room when we leave for the night. The next morning there may be a slight ozone odor in the first floor, but it usually dissipates by the end of the day. There are two rooms that I would say had stubborn odors. This unit has been remarkable at making a difference in those rooms and the entire basement environment has been greatly enhanced. I now use the unit on a maintenance schedule of two to three nights a week for 60 to 90 minutes run time. This unit puts out a LOT of ozone and you will notice it immediately after it starts running. The amount of ozone requires the space to be unoccupied when running. I highly recommend this unit.

STOPPED WORKING NEEDS NEW OZONE PLATE! very disappointed!! Just got it in May. Good Product but OZONE Plate doesnt glow anymore. Trying to find replacement but is not listed!!!

Bought this unit to eliminate bad odor for a recently purchased car which had water coming inside for over a year. Used this machine once for 45 minutes, let the car air for about an hour and the smell is totally gone. Highly Recommended

Ok giving this a 4ish rating. The first one I received had a bad power supply and did not work. :-( BUT, the company replaced it immediately and the new one worked amazingly. :-) Purchased a new used car with a smokers smell to it from Car Max. Ran this for 1 hour in the car Friday evening, let it sit over the weekend with the windows closed and then let it air out in the sun the following week. I get into the car now and smell nothing. Yes, the ozone smell dissipates over time. It was amazing and please be careful and avoid being around the ozone without ventilation.

The product I’m reviewing is the 11,000mg ozone generator. I have to say it is fantastic and does a great job. My home has never had a cleaner smell to it. I have had it for a little over 3 weeks and use it on a regular basis. I have noticed it’s helped with removing allergens I’m my place. I had read a few negative reviews so I was unsure about buying it but I’m glad I did. I will give 2 important points 1. Don’t be in the house when it is in use O3 (ozone) is a disinfectant gas created through an electrical process. It does occur in nature, if you are ever close to a lightning strike you notice a very clean smell, that’s ozone gas. 2. If it is not on or plugged in it DOES NOT produce ozone.

set it up and had it on when I realized that you should not run it in an occupied room. the air definitely smelled different.

This thing is AMAZING! Painting, cleaning, carpet shampooing, and HVAC cleaning - and we were still dealing with stagnant tobacco odor in our home… I ran this thing a couple times in each section of the house, and the smell is drastically improved! We run it every couple months or so now, just for maintenance. The smell left by this machine is very clean and sort of chlorinated. I’m very glad we purchased this machine, when the alternative was an expensive odor removal company! Love this thing!

Over the last two weeks Ive been using this on our townhouse prepping it for sale and removing cigarette smells from the last tenant. It does exactly what its supposed to do: lots of ozone very quickly in a very small form factor. Whether that ozone is going to do what you hope it does is another matter. The way it works, as I presume all ozone generators work, is by using a conductive grid on a non conductive ceramic plate electrified with a high voltage, creating hundreds if not thousands of tiny purple electric arcs, generating ozone the same way a lightning strike does. Its beautiful to watch as the combined effect is a uniform sizzling violet glow inside the box. When I first used it, the lower center of the grid was dark (uh-oh I hope thats not dead) but after three hours of use the whole grid now lights up evenly. I think electricity is cool, but dont worry, this is not a fire hazard or an electrocution hazard, provided you dont do something stupid like turn on the natural gas or drop it in a bathtub. The unit does not generate any heat. It does not vibrate. The fan noise is the predominant sound, not the sizzling of electricity. This is my first ozone generator so I am unable to compare this to other brands or models. I have no idea if it actually produces 9000mg of ozone per hour. I have no idea if its 50% more productive than the 6000mg version. I dont know how long it will last. But as far as generating ozone, it does that very well, according to my nose. It generates it like exhaust from a jet turbine. As far as ozone actually eliminating odors, it works... on light odors only. Our tenant was told not to smoke inside but she did anyway because nursing her addiction was too important to her to waste time going outside. She tried to sneak a few cigarettes inside the bathroom with the fan on but theres no hiding it. Smoking even one cigarette will stain the room with that smell for a long while and it will be obvious to anyone who hasnt had their sense of smell blasted away by years of smoking. We cleaned the bathroom and painted the walls but it did nothing to reduce the smell. However, one three hour ozone shock treatment, followed by 24 hrs of sealed fan action on the whole bathroom removed all the smoke smell except for the fart fan. Those fan blades apparently accumulated tar because turning it on kicks out a brief puff of cigarette smell before sucking it back up and out the roof, so we tried a second three hour shock treatment just in the toilet room with the door closed and the fart fan on. It helped but still didnt completely eliminate the fan smell, so we did a third shock treatment before moving on to the basement / whole townhouse (2400 sq/ft). It takes so long for the ozone to dissipate even after airing out the unit with windows open for 24hrs. Ozone just soaks into everything, which is good as it will seek out and destroy, but I would advise against doing ozone treatments if you plan on showing the unit to potential buyers in less than a week; they will totally notice the smell of ozone. So how does three hours of this unit do on an entire three story 2400sqft townhouse? Meh. Ozone is heavier than regular air so it will definitely all sink to the basement. Its important to have the central fan running continuously. After three hours even the upstairs smelled of ozone but the basement smelled several times more intense. To effectively remove a light cigarette smell from the entire townhouse in one blast is probably not going to happen. Better to isolate individual rooms, but that takes forever with only one generator. The best thing to do is have a ton of fans blowing the ozone up to the ceiling where most smoke rises and condenses. Let the treatment area remain sealed for at least 24 hours while the ozone continues to linger. It sticks around a while so let it do its work. If after all that Ive done the fart fan in the bathroom still kicks out a brief smell Im going to disassemble it and spray it with Vamoose, my backup plan. Conclusion: these units are so small, cheap and effective it would be very hard to justify the bigger more expensive models. I dont know what the actual generation rate is but why care if its 9000mg or 6000mg or even less when you can just run this unit longer, multiple times or, if youre really in a hurry, buy more than one. The half life of ozone is around 3 days in normal humidity, making the generation rate in only one hour relatively unimportant. Its very effective on light odor stains. Heavy stains are going to require actual surface treatment (Kilz primer, Vamoose) or surface removal (sanding down to the drywall, replacing carpet, etc). Also consider that youre probably only going to use this thing a couple of times, ever.

I wont go on about how awesome this machine is for deodorizing in general... rooms, basements, etcetera. What I WILL tell you is how it dealt with the MOTHER of all STENCH. A refrigerator with meat in it that had lost power. I tried for weeks to get the smell of putrid rotting flesh out of this thing and just before I hauled it to the curb, it occurred to me to try an ozone machine. I just popped it in and let the door seal for several 15 minute sessions, letting it air out in between. It smells like its brand new! - well, it did have that slightly metallic/chlorine smell, but that has dissipated quite quickly. $80 machine saved a $1500 fridge! Good buy and I plan to use it again and again -- DO BE CAREFUL TO NOT BREATH THE OZONE AND MAKE SURE YOU FULLY AIR OUT THE ROOMS BEFORE GOING BACK IN!!!
