Works. Takes forever to set up and get going. Gets the job done but is super noisy, slow to get going and overall... almost want to say a waste of my time. I have since gotten a new one that works better without all the extra noise.

There was a stubborn smell in my car that I couldn’t get rid of until I used this ozone generator. I can now understand why these machines are trusted for deep odor removal, and as my first unit, this one has proven reliable and effective. After seeing how well it worked in the car, I started using it around the house for musty closets and other spaces, and it continues to impress. It’s compact but powerful, easy to operate, and well-built, though definitely follow the safety instructions closely, it’s serious odor removal that really gets the job done.

This ozone generator is powerful and easy to use. I tested it in a closed garage and the air felt noticeably fresher after a short cycle. The dual mode switch makes it easy to choose between air or water purification. I used the timer to avoid overdoing it and kept the space well ventilated afterward.It works quickly and efficiently. Just be sure to read the instructions and use it with care.

This is a powerful little machine that can cover to 4,000 square feet of space. In my small studio apartment, it's extremely effective in doing all of the things you want an ozone generator to do. It will be especially useful when I move to a larger place. The housing is tough and rugged, so you know it will last. If you need an ozone generator, this is an excellent choice. It’s so simple to use, even a novice like me can get good results. A word to fellow novices: for your own safety, and others, including pets, read and carefully follow all instructions.

I often help renovate homes, clear out sheds, salvage materials, etc. I often find myself in need of sanitizing/deodorizing, and this this does just the trick. My old ozone generator was much smaller and much slower. This thing pumps it out compared to my little one. You can smell it as soon as you turn it on (careful: leave the room!). It's very easy to use, and all instructions are simple. In fact, it comes with a set of sticker instructions that sticks right ot the machine to help remind you how it works (or if you lend it to someone).I also really like that you can sanitize water with it. Cool!

Last year I accidentally left my windows open in my car during a torrential storm, we vacuumed the water out used fans until dry, but the mildew smell was present. No amount of air fresheners and carpet cleaning was able to get rid of the smell. Yesterday, I was cleaning out my car for a big trip, after vacuuming and scrubbing I was upset that the smell was still lingering. I decided to run an extension cord to my car, turn on the ozone machine and see if it would help. My car is small and based off the user manual it only needed 10 minutes. I rolled up windows and set for 30 (shortest time increment, set an alarm on my phone and let it do its thing.After 10 minutes I opened all the doors, reached in and turned off and then let the doors stay open for another 30 minutes.It was night and day difference this morning when I got in my car; I didn’t have any air fresheners in it, it just smelled airy and light, no mildew smell, no heaviness in the air.I have two teens and spend a lot of time in my car; I’m so excited to have a solution to the stink.Can’t wait to try in our home, just need to arrange pets to be elsewhere while in use.

I don't have any experience using an ozone machine before, but after many times reading about ozone machines being the solution to many problems with smells, I decided that owning one wouldn't be a bad idea. The first test was in my sons' smelly rooms. My 11 year old twins have bedrooms connected by a Jack and Jill bathroom. I noticed their bedrooms were starting to smell rather funky...like smelly laundry, so I decided to try the machine in there first. I put the machine in the bathroom since that was the central area. 15 minutes seemed like the right amount of time to run it based on the instructions, but when we turned the dial halfway to 30, the machine didn't start, so we had to turn it past 30, then backwards to get it to start, then run out of the bedroom and shut the door. We put rolled up towels under the bedroom doors and left that floor while the machine ran. There are only dots between the 30 minute increments, but the assumption, based on the placement of dots, is that the first dot is 15 minutes.After the 15 minutes was up, we ran in, opened up the windows, shut the doors again, and left the rooms for another few hours. By that time, the smell had mostly dissipated and the funky smell was gone.We also used the machine to try to get rid of some bad smells in a used electronic piano keyboard we purchased. I think the previous owner was a smoker but it also picked up some other bad odors...maybe from cooking or something. From what I could tell, most of the smell was in the speakers. We put the keyboard in a bedroom and ran the machine for 15 minutes. This didn't do much, so we did this again, but ran the machine for an hour. This helped significantly with the odor. Of course, running the machine this aggressively did require a lot more airing out of that bedroom, so we needed to leave that window open extensively before the ozone smell wore off. We also made sure to put towels over the air vents (easily done because we have floor vents). It's actually two days after we ran the machine in that bedroom and there is still some residual ozone smell in that room, though we have not had the window open or the doors open that entire time, either.I think the most important thing to prepare for when using these machines is that you allow for adequate time afterwards to air out the space you are using. Make sure the space you are using the machine in is sealed off and unoccupied while in use and then sealed off and aired out for hours afterwards with an open window. The smell is not the most pleasant.I noticed the price of this machine in particular is much higher than many other machines. I don't know a lot about these machines, so I am not sure why this is. I am sure this machine could manage to do much larger spaces than the small rooms it performed in, as other machines claim they could.The instructions for this machine seemed somewhat lacking. It came with tubes for water and absolutely no instructions on how to use them. I know nothing about these machines and how they operate, so instructions on how they work with water would have been nice.
