Our Testing Experience
First Impressions
When I first unboxed the Ozone Generator 45,000mg/h, I was surprised by its compact size—it’s really small, about 0.39 inches in each dimension, which made me think it might not be very powerful. But after reading the instructions carefully, I understood how important it is to use it only in empty rooms without people, pets, or plants. I set it up in a spare room that had a lingering smell from some old furniture. Before turning it on, I cleaned the area as recommended. The machine made a strong ozone smell quickly, which was a bit overwhelming at first, so I made sure to leave the room and ventilate afterward as the instructions said.
Daily Use
Over the next few days, I used the ozone generator in different parts of my house that had odors—like the basement and the garage. Each time, I made sure no one was inside, and I followed the ventilation step after treatment. I noticed the odors faded pretty fast, and the air felt fresher. It was easy to set up and start, and I liked that it didn’t need much maintenance. The smell of ozone itself was strong but disappeared after airing out the rooms for an hour.
Key Features in Action
The high-unit ozone plate is definitely the star feature. Its 45,000 mg/h output made a noticeable difference in rooms up to 2,500 square feet, just as advertised. I appreciated that the machine covered large spaces efficiently, which saved me time. The warning about keeping the area unoccupied is important and helped me stay safe while using it. Also, the advice to clean the source of odor before treatment really worked—when I skipped this step once, the smell didn’t go away completely. So these instructions are not just formalities; they really improve the results.
Long-Term Performance
After using the ozone generator regularly for a few weeks, I found that it continued to perform well without any drop in power or functionality. The machine stayed reliable and consistent. I also liked that it didn’t require complicated upkeep. The only thing to remember is to always ventilate the room after use to avoid any lingering ozone smell. Overall, it’s a solid, high-capacity ozone machine that really works for deodorizing large spaces, as long as you follow the safety guidelines carefully.
