The Ivation Portable Ozone Generator is a heavy-hitting sanitizing solution that delivers impressive versatility for a relatively compact device. By converting oxygen into ozone through an electrical current, this unit tackles everything from stale room air to disinfecting kitchen utensils and even toothbrushes. I found the inclusion of two silicone tubes and two diffuser stones particularly useful, as they allow you to pivot quickly between air purification and liquid treatment.

It covers about 200 square feet using a 20 mg/hour ozone generator, making it perfect for small spaces like lockers or duffel bags. The built-in 5000 mAh rechargeable battery provides an 8-hour runtime, and the clever flip-up hook makes hanging it anywhere easy.
