If you want to offer the full range of ozone uses, you need an ozone generator that can provide a wide range of outputs, including higher rates that can be used with high heat.
The O3Elite Dual has two ozone cells capable of producing ozone up to 100 gamma. This covers it all: insufflations, saunas, ozonating water, cupping, full body ozone, breathing ozonides through oil, and anything else you may need. If you don't plan to use high-heat applications, you can reduce your costs by choosing the O3Elite Single.
