BLOCKER, your personal protective shield against airborne pollutants. • DEFENSE against airborne pollutants such as viruses, bacteria, mold, and offensive odors. • PERSONAL PROTECTION safely sanitizing the air in immediate surroundings. • EFFECTIVE using the disinfectant power of ClO2 (chlorine dioxide) recognized by the US Food & Drug Administration (FDA), World Health Organization (WHO), and Japan Ministry of Health. • PATENT PROTECTED in the USA and Japan, Blocker employs a unique solidified ClO2 formulation. • WEARABLE, compact, and lightweight, Blocker is easily worn around the neck, clipped to the outside of a shirt, or attached to a handbag. Blocker is fully effective for 30 days and is also safe for use by pregnant women and children. Why Choose Blocker? Other virus blockers rely on “stabilised” chlorine dioxide as their primary active component, which actually has little ClO2. These products fall far short of the Blocker when it comes to establishing and maintaining an effective pathogen exclusion zone of up to 1 meter around you. Blocker’s patent protected formulation has undergone tests to verify efficiency and safety for the user. Made in Japan. ***** If any discomfort is experienced, discontinue use immediately.
