Enerzen Ozone Generator 60,000mg Industrial O3 Air Purifier Deodorizer (60,000mg - Black)

UPDATE: SUPERIOR PRODUCT! It is still working and doing a great job! I run this machine hard for hours, daily, while I am at work (5-8 hrs) and often throughout the evening. To circumvent the 2-hr timer so the Maxine would run constantly, I removed the timer’s knob, used needle nosed pliers to to turn the timer dial and angled the pliers inside the dial which prevented the timer from turning. Rating changed to 5 stars because of its lasting functionality and durability. My boss had a (Ecoquest) Living Air Classic XL-15 that was amazing. I thought I'd shop for one for personal use in my home to eliminate smoke odors. WOW...then I saw the price of the Living Air XL-15 and it was way more than I was willing to spend. Don't get me wrong, the Living Air XL-15 is worth every penny. It does an amazing job of ridding every single odor from your home, car, basement etc... and it leaves a fresh clean smelling atmosphere.... and I highly recommend it to those who have from $300 - $500+ to spend. I just don't have that kind of money available to spend. So I shopped around. I read the reviews and did my homework on the output levels of negative ions and etc... that make an ozone generator one of quality. Enerzen had high ratings and seemed to fit the bill according to the spec.s I received it and put it to use. I love it! The housing is sturdy. It works well and covers the area it advertises that it does. I placed it in the basement of my three story townhouse. It cleaned the air in the basement, on the first level and extended to the 2nd story also.... of course, its affect was not as strong on the 2nd story which was farthest away from the unit. The solution to that was that, later, I placed the unit on the 1st story of the house to thoroughly hit the 2nd story. One thing I wish I thought about prior to buying was that this has a timer and only allows the machine to run for 2 hours at a time. I didn't want to have to be at home to run the generator. When I borrowed my boss's living air generator, I would turn it on and let it run all day while I was at work. When I arrived home, I would turn it off and crack or open the windows to ventillate the ozone which I am told you should do - - for health reasons you should not sit in the room/area in which you will come into direct contact with the ozone generated air. Because of the timer and the fact I can only run it for two hours at time, I resorted to sitting it in the basement and shutting the door to let it clean that specific area. After two hours I run down and reset the machine for another two hours. I do the same for the 1st and second levels. I run the generator in specific rooms now that are shut off from where I am spending time, which is a slight inconvenience, but other than that I am very happy with the generator and its performance.

Original review Dec 2021: Added update July 2025 below. My house has always had an odd smell since I bought it 12 years ago (2008). My sister could smell it on my clothes even when I went over to her house. Perhaps a bit of mildew as I've noticed dusting on wooden surfaces, windows, doors, and cabinets. I've cleaned them, and even put a fresh layer of polyurethane over all my wood surfaces (which helped briefly). I don't see dusting anymore, but the smell persisted. With the pandemic, lots of talk about treating air with UVC. That triggered memories that UVC lights are commonly used to disinfect operating rooms at work. So I gave it a go with some lights I picked up from Amazon. Well, success! But hard one as I had to do each room like 6 times, moving the light each time. From reading reviews of UVC lights, I came across the idea of ozone generators. They work much more globally that lights, filling spaces the lights cannot touch effectively. Both types of units are dangerous and have to be used with caution. I've been burned by UVC lights in the operating room with tidbits of exposed skin. And ozone is tremendously harmful to life, not just microbes. In particular for humans, toxic for lungs. So you need remove plants, pets and people from your home. I bought this unit in cold weather so opening windows was out (I had storm windows on anyway). With a bit more research I found that the ozone breaks down over time. Depending on how much you generate determines how long before it is safe to reoccupy. However that is hard, and I found recommendations that 2 hours after using generator is a very conservative safety margin (many sites and manufacturers suggest one hour is enough). Thus it was easy to simply use for the maximum time either whole house or per room and add 2 hours and not bother with airing out the rooms or house. Easy to use. Love the mechanical timer, a simple old fashioned dial just like a kitchen timer. No delay before starting so be prepared to leave the house immediately. There is a distinctive smell after using that in my experience lasts about one day at most. Not an unpleasant smell at all, smells clean. Not unrelated to positive ion generators I think. Good value, and I read tons of positive reviews here. As a huge bonus, it kill spiders!!! Other insects as well presumably. July 24, 2025 Three and a half year update Lots to share here. I have used this roughly 5 hours a week on average, or about 800 hours total. Typically 3 hours on the timer, and then I delay returning home for another two hours to let the ozone deactivate. After 2 years of highly successful use, after five hours away, I came home to a smoky home - light enough that I had to look twice. Later it was highly obvious on return home. I attempted to contact Enerzen about safety, both fire hazard and lung safety but they never replied. I continued to use another year and a half, using my internet controlled Nest thermostat to run the furnace fan for two hours so I at least filter whatever the smoke is. Now three and a half years later, it appears my usual once a week house treatment is no longer as effective. So I figured that I should probably replace the ceramic ozone plate. Received that today and it doesn't fit (per several other reviews here). See attached picture. Looked easy enough to modify, just use a Dremel to cut out a divot in the replacement plastic plate. Wrong! Made from metal, a no go with a Dremel. So I did some more disassembly to modify the bump on the socket where the plate plugs into. Also looks like plastic, but simply coated steel that appears to be hardened. I went through a new cutting disc on my Dremel that is usually more than sufficient for cutting through a bolt the same size, and only cut about 1/16" at most. I then tried a bench mounted belt sander - did nothing. A hacksaw refused to cut as well. The "manual" that came with the unit was terrible, picture and description of how to replace plate was totally inadequate, not even a model number (but neither does the main Amazon listing, nor does the Enerzen store). It turns out this is the 0-777 model which the Nispira replacement plate specifically says it doesn't fit. But it is the only one sold by Amazon whose picture is a match the model I purchased. It is not sold by Enerzen or any other vendor online. So I guess I now have a pile of scrap metal. One other thing I didn't catch is that Nispira said their plate has an output of 3,500 mg/hr of ozone. Enerzen rates my model 0-777 at 10,000 mg/hr. It also rates the 0-555 model which the Nispira replacement is supposed to fit at the same 10,000 mg/hr. Something fishy going on here. Nispira also rates the replacement plate with a 5,000 hour life. That is also a disconnect with my original plate not making it more than 500 hours before smoke started forming. By the ways, some of the plastic (not all) inside the unit has deteriorated from ozone exposure. Possibly that is where the smoke came from. I'm not sure how to proceed. I guess I could purchase the far more expensive 0-555 unit ($120 versus $75 0-777 unit both with same ozone rating), and take it apart and see if my replacement Nispira plate fits it. Of course, that seems iffy since the Nispira plate is not rated for the same output. Update August 4, 2025 I didn't explain the attached photo. The plate on the right is the original plate on my 0-777. I managed to snag a new 0-555 on eBay for an amazing $45 delivered! Without disassembling it I could see through the grill that it uses the same ozone generating plate as my 0-777. If you need to replace the plate on either model, make sure it looks like the plate on the right. I did manage to get the right plate for my 0-777 from Oion (the manufacturer of Enerzen products) standalone web site. $12. It was listed in the Amazon Enerzen store but as out of stock. And even Oion's site, it said there was only one left. And boy, did that new plate make a difference. Lots more ozone production, and no smoke/fog produced. No need to run my furnace to filter the smoke before I returned home. House smelled far better than before I replaced it (similar to using it when new). But it looks like you can only count on 500 good hours of service before the plate should be replaced. Probably most people who buy this just have a one time need for it, like in a new apartment or house, so this issue may not be reflected in very many reviews here and may not be important to you. I depend on this thing for odor control at least twice a month, but after two years of use, I was doing it weekly. Think I'll be back to two week intervals. If you replace the plate on your unit, be aware that you need some thermal paste to install it to transmit heat better to the heat sink. I did note that when I took off my original plate, the thermal paste coverage was not optimal. That could be a cause of early failure on my unit - 500 hours versus a claimed 5,000 hours. I used it for the maximum 180 minutes each time, so that would be worst case for heat production. I took care when replacing the plate to have maximum coverage on the thermal paste I applied. And I now have a second unit (the 0-555 from eBay) as backup. In doing some research in trying to replace my plate, I heard about recommendations on a site selling commercial ozone generators ($500 up to a couple thousand) talking about "shock" treatments for odors - which means hitting rooms with massive amount of ozone. Sometime this year, I will try both units at the same time to see if the treatment lasts longer. The site was really talking about hard to get rid of odors, not so much how long a treatment might last, but worth a shot! Congrats on making it this far in this review! Really long but a lot of information that hopefully proves useful to those who read this far.

We recently moved into a flat that had clearly been heavily smoked in. The smell of smoke just wouldn't shift - we had the windows open every day, but closed them every night. Each morning, we wake up to the smell of stale cigarette smoke all through the flat. I'd read online about ways to get rid of cigarette odours, and everything kept coming back to Ozone treatment. Finally, I decided enough was enough and bought this machine - and WOW. I am genuinely impressed. We ran it for various times in different rooms - in the lounge and the hallway where the smell was strongest we did a couple of treatments at different times (30 mins/45 mins, even up to 1.5 hrs). The ozone smell is quite distinctive and harsh on the throat so make sure you don't breathe it before you can open all windows and air it out fully. It has made such a huge difference to the flat - it was horrible to smell cigarettes every single day in every room. I really recommend this machine.

Es un muy buen producto lo recomiendo, es lo que esperaba además llegó antes de lo esperado.

I have been trying to get rid of old cigarette smell which lingers in our house from a previous owner. I was facing having to wash all the walls with sugar soap then seal them and repaint all the walls and ceilings, plus clean all the woodwork. Would have cost a lot of money and taken a lot of time, which is something I don't have much of. I bought this after reading some reviews, took it upstairs and ran it for about 20 mins. I then went shopping to let it do its work, then came back and opened all the windows for about an hour. The smell was completely gone! Not just the tobacco smell though, any other smells were gone too. It smelled slightly like a swimming pool that had just been cleaned. Some notes: as 03 is heavier than air, some of it went under the door (which was closed) and then down the hall and down the stairs, so I could smell it downstairs too. Not a problem, it disinfected/deodorised the stairs too. The next day some of the original smell is only very faintly detectable. But another dose or two should do the trick. In sum, this has saved me a lot of time and money, and I'm really pleased I bought it.

Guys, this is worth the buy, we spend a lot of money on pesticides and other bug sprays but I use this once in my room where I had small bugs that came in and now my room is bug free. This goes into all nooks and crannies. we are best control cannot penetrate since this is gas. it has also removed certain orders in the room that were prevailing for quite some time and I didn’t know where this is coming from.

La macchina è solida, potente come descritto, facile da utilizzare. È sufficiente collegare l’alimentazione e ruotare il timer per il tempo sufficiente a coprire la zona da sanificate, come da indicazioni. Questo ozonatore ha sostituito un precedente modello di altro produttore, che aveva problemi di funzionamento e, rispetto al precedente mi pare vada molto meglio. Unici due nei: 1) il timer non permette di utilizzare tempi brevi, parte da circa 30 minuti minimo; 2) IL CAVO DI ALIMENTAZIONE HA LA SPINA INGLESE UK, QUINDI PER UTILIZZARLO È NECESSARIO AVERE UN ADATTATORE, OPPURE UN ANALOGO CAVO CON PRESA ITALIANA O SHUKO. Per questo secondo lato negativo ho messo solo 3 stelle, un prodotto venduto in Italia non può essere corredato di spina UK! Per il resto, finora, ha un funzionamento egregio ed è utilissimo per sanificare gli ambienti da batteri (molto importante in questo periodo) e muffe, oltre a deodorare,
