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. Just a heads-up: you have to hold the power button for a second or two to turn it on, as it doesn't activate with a single tap. It even doubles as a portable USB charger for your phone.
