This ozone generator is designed for eliminating odors effectively, offering a robust ozone output of 48,000mg/h, making it suitable for spaces up to 4,000 square feet.

Its compact design and lightweight make it easily portable, an ideal solution for use in cars and other enclosed areas like basements and dumpsters. The device is straightforward to operate, featuring a manual timer to adjust ozone generation and a 'HOLD' function for continuous operation. However, users must remember to ventilate the area well after treatment.

While its safety precautions are necessary, they limit convenience, as it requires users to vacate the space during usage. Its durability is supported by various certifications, ensuring reliable performance in commercial settings. Despite its efficacy, it isn't available for sale in California, which could be a limitation for some users. This generator is ideal for those needing a heavy-duty odor removal solution but who can manage the specific safety requirements and operational constraints.
