EnerzenCommercial Ozone Generator Industrial O3 Air Purifier Deodorizer Sterilizer (O-uvc3 3 Ozone Plates)

I use this to deodorize auto interiors. I run for an hour and then unplug the machine and leave the vehicle closed up for an additional hour then open all doors and trunk or lift gate and let it air out for 15 minutes. If needed I will repeat the process a second time but that is rare. Keep in mind that vehicles with cigarette smoke smell will need a thorough cleaning of EVERY surface in the vehicle to remove the residue. If this first step is not done in a vehicle that has been smoked in for a period of time you will not be satisfied because the smell will come back. DO NOT leave the machine on for an extended period of time as this can cause more harm than good. Please research How to use an ozone generator. It explains how to use these machines properly. Unfortunately this is not in the manual. I HIGHLY RECOMMEND THIS MACHINEDavid

The office in the house I just rented reeked of tobacco smoke. It was so bad that it made my eyes water. The landlord had already shampooed the carpet and painted the walls. She reimbursed me to buy this machine. After 2 overnight 8-hour sessions, the odor was completely gone. Amazing. The odor hasn't come back. This worked way better than my expectations. I am not sure the cheaper units will do the job as well. They only run for 3 hours, and may not produce enough ozone. Ozone generators are apparently banded California on the bizarre theory that they cause air pollution. They do the opposite. And they eliminate a documented health hazard. There is evidence that long term exposure to this "thirdhand smoke" can cause cancer.

Hopefully you already did the research and you're certain you __NEED__ an Ozone generator. If you didn't, you should - Ozone probably doesn't do what you think it does and it's probably inappropriate for your situation - and I can say that with better than 75% confidence. Most people are under the illusion that Ozone destroys odors and makes things "fresh". Wrong. Ozone is NOT an air 'freshener' OR an air 'purifier' - in fact, it has more in common with SMOG than it does fresh air! Ozone is a toxic (yes, TOXIC) gas that enables rapid oxidation of certain organic compounds in heavy [usually very unsafe] concentrations. But in this case, the cure might be worse than the disease, so PLEASE, PLEASE do your research first and learn about what this machine makes before jumping in and filling your home up with Toxic O3 gas. Visit the EPA's web site to learn what Ozone is and isn't BEFORE you buy this machine.This machine is a monster. If you need O3 in concentration from a compact sized machine, this definitely gets the job done. It's quiet, compact and monstrously effective at making toxic O3 gas. O3 production is variable, from OFF to "maximum/100%", but I found that even at its lowest setting, it still makes an enormous amount of Ozone. We use it to control pet odors and deep fryer smell, and while it does both very well, it might cause more harm than good in certain cases. Any space this gets used in must be absolutely devoid of ANYTHING living - including fish, plants, pets, people, alien life forms, food (i.e., fruits), zenomorphs, expensive artwork, fresh stickers you care about, screen-printed clothes, etc... It is VERY good at killing life - especially plants that often get forgotten about: They might look fine the morning after, then they die an uncontrollable death several days later.The Ozone created by the Enerzen Ozone generator does NOT purify air - the small HEPA filter on the back of the unit does. Also, the generated Ozone does NOT "sterilize" anything - the small internal UV bulb does. The internal fan runs at a fixed speed and is fairly quiet. The timer on the front supports 0-24 hour operation, or HOLD. Ozone generation is variable from OFF to 100%, but it is very unclear is the dial percentage markers actually match Ozone production from 0 to 15kmg/h (i.e., does 50% actually equal 7,500mh/h?).Exposure to the high concentrations of O3 created by this unit irritates eyes, nose, throat and lungs and could take you several WEEKS to recover from - so be aware of where people are in relation to where the machine is running. Understand that it can and does go through vents to adjacent rooms, and even small amounts can cause serious headaches and respiratory problems.This machine is an equal-opportunity destroyer: It will destroy cells in your lungs, throat and sinus, damage skin, eyes and other tissues, and get rid of certain organic odors. Make sure you "really" need O3 and not just a good cleaning or a an actual HEPA air filter units instead.Buying this unit for air purification or air filtration purposes is a mistake. The HEPA filter on the back of the unit is far too small to make any kind of remarkable difference, and the UV bulb inside the unit is too low-wattage to effectively sterilize any significant volume of air. I essentially treat both of these two features as gimmicks when it comes to the designed purpose of this machine - to produce massive amounts of Ozone.Buyer beware! DO YOUR RESEARCH FIRST!

Strong smell when reentering house. Don’t like having to air the house out for an hour after in the winter

I purchased three— 2 with a lesser output. They all end up not working within a month or so. The fan was the first to go.
