Using a spa ozonator not only eliminates known bacteria, viruses, cysts, yeasts, mold, mildews, and chloramines, it will also reduce metallic staining and scale build-up. Color and odor are removed to keep your spa clear and odor-free while oxidizing inorganic substances and volatile organic chemicals, such as lotions and makeup. This technology is not new. Since the turn of the century ozone technology has been used to purify drinking and municipal water. Because it leaves no chemical byproducts, is eco-friendly, and won’t irritate skin or eyes ozonators have been the sanitizer of choice at the Olympic Games since 1984.
