  • GETS RID OF THE SMELLY BITS YOU CAN'T SCRUB AWAY: Ozone reacts with odors in the air, water, fabrics, and walls to remove, instead of mask them. Unlike other types of air purifiers, it does not require air passing through the machine to remove odors.
  • COMMON USES: Deodorize cars, boats, dumpsters, kitchens, bathrooms, basements, flood and fire affected areas, as well as any cooking, smoking, pet, "musty", or general odors.
  • EASY OPERATION: Turn the timer knob. Leave the space. When ozone generation is finished, allow an additional 30 minutes for any residual ozone to revert back to breathable air.
  • WARNING: All ozone generators are meant to be operated in unoccupied spaces only. Remove any people, pets, or plants. The space may be re-occupied after 30 minutes of "airing out". Not available for sale in California. EPA Est. No.: 94263-CHN-1

Description

Ozone neutralizes and removes odors, instead of masking them. Unlike other deodorizing methods, ozone actually searches out and neutralizes odor molecules. With three oxygen atoms in each molecule, rather than the two oxygen atoms in the air we breathe, ozone is unstable. Its extra oxygen atom can detach and grab onto odor molecules, making their composition neutral. Deodorize areas you can't clean. Ozone reacts with odors in the air, water, fabrics, walls, and ceilings. And unlike other types of air purification systems, an ozone generator does not depend on the air passing through the machine to do its job.

Great item, but BE SAFE!!!
Color: Silver Size: 6.75"(L) x 8"(W) x 5.75"(H)
To start with, please research this item before using it. This can be *extremely* dangerous to you and your family's/pet's health if you don't know what you're doing. With that said, we love this thing and it has not given us any issues or problems in the nearly 2 years we have had it. If you are careful and follow proper safety precautions this can do so many good things. If your car smells like rotten milk, if you bought a used car that reeks of cigarette smoke, if you have water damage and/or musty mildew or mold on items, this can help. Ozone has the ability to kill the bacteria, and other living organisms that are responsible for those horrific smells that come from mold, mildew, smoke, rotten milk, etc...that said, being that ozone kills bacteria and organisms, it will also kill humans and pets if they are exposed to ozone, so do your homework on how to be safe before using this item! Don't take that warning lightly. We have used this item several times to remove mold from stuff from our old house, and to clear up mystery smells in cars we have bought. Basically you just set the product up in a space where humans and pets will not inhabit, seal all doorway cracks that may lead back to the house or living areas and crack windows in the room where the unit is. You don't need much to fill small spaces, so unless you have a mansion or are trying to fix a whole house, you shouldn't need more than about 15 minutes of run time following by a few hours of time to let the ozone do it's thing. Ozone is heavier than air, so it can seep through the bottom of doorways and down stairs or through vents, so if you are using this indoors, be sure to block the bottom of doors or low vents with towels and keep any family members or pets away from the room you're doing treatment in. I know it may sound like I'm over emphasizing the danger, but seriously, it's no joke. This has helped us in recovering family keepsakes and memories that we thought we would have to throw away when we found out there were mold problems in our last home. We often set up the ozone machine in a small tub with items that need to have mold killed off and run it for just a few minutes and let it sit in the ozone for 12 hours or so, then repeat as needed. Once we finish the treatment, we open all doors and windows in the room and several in the house to let the ozone dissipate. Do not go in close proximity until the "petrichor" smell is gone. That smell of fresh rain(or petrichor) is the smell of ozone, so if you smell that, step away, that's bad for you and can damage and irritate the tissue in your lungs. We used it once to treat a car and we probably ran it longer than we needed to. We sealed all doors and windows, put a box fan in the car to circulate the air and ran the ozone generator for about 15 minutes and let it sit with the fan blowing and car closed for the next 24 hours. The next day we started the car, ran the air on recirculate for a few minutes, closed up the car and did another 15 minutes on the ozone generator then let it sit another 24 hours with the box fan blowing. After we finished the second treatment with it we opened all the doors in the car, turned the air on to bring air from outside and let the air run with the car on for about 30 minutes with everything in the car open. After we turned off the car we left the car sit completely open for around 4 hours. The next day the smell was still there and was still pretty strong. It took about a week of leaving the car open a couple hours a day before the ozone smell was gone, but it did fix the bad odor issues. So be careful not to overdo it, a little bit goes a long way. Keep in mind that you still want to find the source of the smell and remove it before treating if at all possible. Bottom line, this has been a lifesaver in recovering sentimental items that can't be replaced because of the memories. It has been well worth the price, even for the few times we have used it, because of the memories it has saved. Absolutely worth the price...but again, please be safe and cautious. ... show more

I had a musty-smelling basement and pet litter odors (we have cats) - this unit did a great job!
Color: Black Size: 6.75"(L) x 8"(W) x 5.75"(H)
I will put in the full product names again further down, since Amazon seems to mix and match product reviews. The unit I'm reviewing here is the Enerzen Commercial Ozone Generator 6,000mg. I have previously had an OION Technologies B-1000, which is okay and suitable for continuous operation. The Enerzen unit is NOT for continuous use - it makes way too much ozone to use it that way. Read on ... For $80, this ozone generator is a great buy! It puts out enough ozone to knock back the musty and pet-litter odors in our entire basement in just a few hours. Details follow. We have multiple cats, and one upstairs bathroom was their litter-box room, along with several boxes in the basement. When we decided to move the upstairs litter box elsewhere, I cleaned the room (including wet-mopping the floor), but the cat-pee spell persisted. I tried a single-room "air purifier" ion generator (OION Technologies B-1000) and while it did help, it was not enough. So I bought this unit (Enerzen Commercial Ozone Generator 6,000mg) and let it run for 30 minutes. Major improvement. Just to be thorough, and because I'm a firm believer in overkill, I then ran it overnight. Odor is GONE. The basement experience was similar. In addition to pet odors, we have had water get into our basement a couple of times - we're not talking about sewage, here, just outside water getting in through the foundation during heavy rain, and a one-time plumbing problem. I finally got the indoor-outdoor carpet fully dried, but there was a musty, mildewy, perhaps moldy odor. Ick. I rigged up a pretty good air-circulation setup, which helped, but the odor just persisted. Enter the ozone generator. I ran it for a couple of hours, being sure to keep the basement closed off for an EXTRA couple hours to let the ozone degrade back into harmless oxygen, and the odor was almost gone. So I ran it again, this time running for six hours overnight, with a few hours afterward to let the ozone dissipate. The musty smell is GONE. Has not come back. We now have our pet litter boxes down there, and if I don't keep up with them, the litter smell (kitty pee and poo) gets pretty nasty. I then 1) chide myself for not keeping up, 2) clean the litter boxes, and 3) run the ozone generator for a couple hours and the basement is PERFECTLY LIVABLE!! I highly recommend this product. Enerzen Commercial Ozone Generator 6,000mg. A caution - ozone is bad for people, pets and plants. Do NOT run this unit without closing the space off from people and pets, and be sure to take your plants out. When I run this in the basement, I shut off the central air while it's running and for a couple hours thereafter, so we don't get the ozone throughout the house. The time or two that I have forgotten to shut the AC down, we got a pretty strong after-the-thunderstorm smell throughout the house, which reminded me. No ill effects from that, but it was a pretty brief exposure. Also, I'm told that ozone is bad for, well, pretty much anything that breathes. It does seem that we don't have nearly the population of creepy crawlies in the basement anymore. Perhaps spiders, centipedes and other bugs do not tolerate a heavy dose of ozone for hours ... ? ----- Edit added in 2026 I have now purchased THREE of these (since 2020). I have loaned them out to friends & co-workers to help with musty basements and pet smells, and they all report that these ozone generators are VERY effective and much appreciated. I had occasion to look in through the grillwork at one point, and I could see that the violet light on the ozone-generating element was NOT covering the element. I read that it was possible to REPLACE the element, but I wanted to try CLEANING it first, so I took the cover off (a few sheet-metal screws), and was able to disassemble the inside enough to get the element loose in my hand. It was pretty easy to clean, with a bit of spray cleaner, a little toothbrush action and paper towels. Reassembly did not go as well - I cracked part of the mount . . . but it didn't seem to matter. I got it back together enough to hold the element securely in the air-stream from the fan, and when I fired it up, the violet glow covered the entire element again. So, easy to maintain! Again, these ozone generators are terrific! A great buy! ... show more

Very powerful mini machine, n3ver used before and it worked out pretty well. I turned it on in my car for 1 hour (without having a smell issue, just for maintenance because I heard it kills all the bacterias that we don't see, and old smells) and honestly is so strong that you should let your car vent after that for at least 1 hour. After 2 days de car the car doesn't smell to that treatment anymore. 100% recommend, it's a light one, very small and it's so easy to used, is just plug it and turn the timer. ... show more

So I checked on Amazon and here seems like a cheap way to handle the smell
Color: Black Size: 6.75"(L) x 8"(W) x 5.75"(H)
My home caught fire and after going through insurance and all the clean up. I was still getting a slight smoke smell in my living room. Before moving back into my home the fire restoration company said they can run the ozone machine again before I move in. They said sometimes you have to run it for multiple days before all the smell goes away. So I checked on Amazon and here seems like a cheap way to handle the smell. Because I didn't want the smell coming back after I moved back into my home. Well the restoration company ran their ozone machine for 1 day then I had to move back into my home. Then the smell came back after 3 days. So I ran this machine while everyone was at work and school, the only thing is that there is a 2 hour timer on it. So I had to go home every few hours and reset it. That is the only gripe I have about this machine. I ran this machine for 3 consecutive days while everyone was out of the house without any problems whatsoever and it worked! After 3 days there is no more smoke smell and it hasn't come back. I haven't used it for the house anymore. My sister did buy a used car and it had an awful smokers smell inside of it. I told her I had this machine that is suppose to get rid of smells so we gave it a try. We kept the car running with all the vents open and the air circulating. It did a pretty good job... It didn't get rid of all the smell but the majority of it did go away. I told her if we ran the machine in the car a few more times it would probably get rid of the rest of it. But it got rid of most of the smell so she said it was fine so that she could use her car. But after the initial use at my home and my sisters car - I don't use this machine anymore. I'm sure I will use it again some day for something but for now it just sits in the garage. - If you have learned anything helpful with this review, please let me know by clicking the "yes" button below.

Got Pets? Kids? Lousy Tenants?
Color: Black Size: 6.75"(L) x 8"(W) x 5.75"(H)
A product that lives up to its claims. About 2 years ago, I moved into a townhome I had been renting out for several years. I found that the tenants 2 college age boys had moved in (against lease terms) and were chronic smokers (way against lease terms). Luckily, they had locked themselves into the master bedroom and bathroom but did a number on the place above and beyond the deposit over the course of 3 years. The smell was horrific, and a month after painting and replacing carpet, the stench was still terrible. I got a quote from ServPro for about $2700, which I couldn’t afford at the time. I noticed in the quote that they’d be using ozone generators. I was already familiar with the technology behind them, and had used similar technology years before. Unfortunately, they’re illegal in CA as of 2017, because CA knows what’s best for us. Apparently, people can’t read the warnings and would sit in a room with the things running. Or more likely, legislators have invested stock in ServPro and other smoke damage experts who are undoubtedly quite happy about this law. So, I bought the machine, had it shipped to a friend in TX who then forwarded it to me. In a 20x15x10 room, I ran the machine for about 12-14 hours, and then again in the bathroom (the worst) for another 12. It was amazing. It smelled springtime fresh and the odors never came back. The light fixtures were still yellow, but that was an easy fix! Since then, I have lent the machine to realtor friends for pet odors, smokers and general mildew smell in laundry rooms and garages. Let me tell you, cat urine is a category all by itself. In all cases, the machine did its job. Recently, I moved into another vacated property and ran the machine in the garage for a few hours. I had already bug-bombed the place a few weeks previously. There were dead spiders everywhere, and the wet, mildewy smell was gone (apparently the tenants had an aversion to closing windows and doors during rainstorms). Pros: - Oxidizes all organic matter (smoke, mildew, pet dander, pet urine, bugs, mice, etc.) - Compact size - Powerful - Inexpensive - Harmless to foodstuffs etc. Cons: - No filter - No replaceable grid - Only oxidizes organic compounds/matter not chemical caused odors - Illegal in CA and possibly other states - Must vacate area and air out before coming back - Can possibly begin to break down plastics, rubber, foam etc. with overuse If you’ve got teens active in sports, you don’t have to worry about buying all kinds of odor masking laundry garbage for their room or clothes. Hang their stuff in a garage, sealed closet or laundry room and turn on. Stick it in Jr’s room while he’s at practice. Cat box stinking up the place? Puppy make a mess on the carpet? Clean it then run this baby for a couple of hours. Inherit Uncle Bob’s Plymouth Roadrunner, but he smoked cigars? A lot?!? Stick this box in the car and run for a few hours. Problem solved. Got spiders in the garage? Ants? This thing will make short work of icky bugs. As of 8/7/21, Shawn Wood (on Youtube) who has a show called Moustrap Monday will be testing to see if these either kill mice/rats, or more likely, are such an irritant that it drives them away. I’ll update once he tests this out. So far, he’s eliminated a yellow jacket nest, which is impressive. If there’s a downside (besides potential overuse breaking down plastics) it’s that you need to allot time necessary to use it. That also includes time to air out a room. So you’ll need to plan ahead. Make sure the kids aren’t going to be coming in, and that there’s time to air out (with fan assistance if needed) so people and pets will be safe. Plus, it smells *so* good afterwards! Like after a rainshower/thunderstorm. Are there better machines as far as longevity and design? It appears some are designed for longer use with replaceable parts. They’re also more costly. When I bought this, I wasn’t sure it would work. However, I’d buy the exact same machine again. I’ve used it many times, lent it out many times, and it’s not skipped a beat. Unless I’d need to do a very large space and was pressed for time, I’m not sure what the advantages for a larger machine would be. I’m very happy, and think you will be as well if any of this looks compelling to you. So, recommended? Without hesitation, 5 stars. ... show more

Recommend this if you want a top quality mid-range ozone generator
Color: Silver Size: 6.75"(L) x 8"(W) x 5.75"(H)
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. ... show more

Review Image by yticolev
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. ... show more
