Portable ozone generators are compact devices that use ozone to purify and deodorize the air. They are an effective solution for eliminating odors, bacteria, and viruses in small spaces such as cars, closets, and bathrooms. These generators work by producing ozone, a powerful oxidant that breaks down and neutralizes pollutants in the air. Unlike traditional air fresheners, ozone generators do not mask odors but instead attack the source of the problem. They are easy to use and require no maintenance, making them a convenient and affordable choice for improving indoor air quality.
