Review: Helped reduce odor with regular use - I used the OdorStop OS4500UV Professional Grade Ozone Generator during a home remodel where the house had never had a dehumidifier and had that lingering damp drywall/insulation smell. With regular use, it definitely helped reduce the odor and made the space much more tolerable while we were working. That said, the real solution ended up being addressing the underlying humidity issue. Once a dehumidifier was added and moisture was controlled, the smell was truly resolved. The ozone generator was a helpful tool in the process, but not a standalone fix for an ongoing moisture problem. Where I really see this unit shining is with odor sources like smoke or one-time, stubborn smells. It’s powerful, professional-grade, and effective when used correctly. I would absolutely recommend it as part of an odor-removal strategy, especially for smoke or renovation-related smells—just pair it with fixing the root cause for best results.
Review: OMG IT WORKS!!!! And they have an incredible customer service team!!!! No more SMOKE! - I didn't think it was possible to get rid of musty, smokey odors. Thankfully, I was wrong! My son recently rented an apartment in a non-smoking building. When we were shown the apartment, it had been recently painted and the windows were open so there were no noticeable odors. Once the paint dried and the room started to warm up, it became pungent with a smell of smoke. It was extremely unpleasant, especially to someone who doesn't smoke and has asthma. We had the carpets professionally cleaned TWICE, had every surface sanitized, and ran two air purifiers on high for a week. It didn't work, and we weren't sure how he would be able to live there. I desperately searched for help when I decided to contact a professional smoke removal service. They are able to remove smoke odors from a house after a house fire (and musty, moldy smells after flooding). When I asked how they did it, they told me about the ozone generators they used. I didn't even know that these devices existed. I started to research ozone, how it works, and decided to find a unit to purchase. We weren't able to leave the apartment overnight, so we ran the unit using the timer which we set to shut off an hour and a half before he returned home. We ran it for 6 hours on two consecutive days, and the smell is COMPLETELY GONE! What was left was a fresh smell, and the air actually felt lighter and cleaner. I couldn't be more excited with the results. The customer service team is also incredible, extremely prompt in responding, very courteous and helpful. My first unit didn't seem to be working, and I called for help. They tried to help me troubleshoot the issues, but unfortunately, my first unit may have been defective. They replaced that unit with another one, and I received the new unit in a couple of days - with a prepaid return label to send the other one back. I tried the new unit, and it worked like a charm. I have read a couple of reviews that complained of the smell that the ozone generator creates. There is a very strong ozone smell that comes from the unit when it's on and shortly after using it, but the smell dissipates quickly. I wouldn't say it's a bad smell though. It kind of smells like it does during a thunderstorm or right before a rain. To me, it smells like super fresh air. They provide you with safety instructions but you should know that this can only be used in an unoccupied area. And if you have pets, you need to be sure that you take them with you when you run the unit. If you are looking for an effective way to eliminate odors, I would highly recommend this product.
