The O3Elite is the next generation of low wattage, low frequency ozone generators. Unlike dangerous high voltage glass cell generators, the O3Elite will never burn out, is very quiet, and operates cool so the ozone is not destroyed by heat (this provides a more stable ozone output; you might want to see this article: Glass vs. Ceramic: What’s Best for Ozone Generators?). Glass cells generate a tremendous amount of heat which compromises the quality of ozone. The O3Elite comes standard with Luer locks, universal worldwide voltage, wall mounts and cleanable cells.
