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.

While its safety precautions are necessary, they limit convenience, as it requires users to vacate the space during usage.
