Chlorine Dioxide (ClO2)
How ClO2 Works
Activating Blocker
is a patent protected personal shield against airborne pollutants such as viruses, bacteria, mould and offensive odours that uses Chlorine Dioxide (ClO2) to sanitize the air in your immediate surroundings
Chlorine Dioxide or ClO2 gas is a chemical compound with a track record worldwide as a first-choice disinfectant for anti-microbial applications. It has proven its effectiveness against pathogens such as viruses, bacteria, mold, and offensive odors.

Usually stored in a liquid form, it is also used to disinfect drinking water.

ClO2 as a disinfectant and environmental purification agent has been approved by:

• U.S. Food and Drug Administration (FDA)
• World Health Organization (WHO)
• Japan's Ministry of Health

How Chlorine Dioxide (ClO2) Works
ClO2 works through oxidation by decomposing the protein in the cell membrane surrounding pathogens such as viruses, bacteria, etc. When the ClO2 gas comes into contact with pathogens the cells are ruptured and destroyed.

Activating Blocker
The patented Envroy ClO2 solid formulation is contained in a special fine mesh paper envelope that is then encapsulated in a thin aluminium package which is fully sealed.

Once the user removes the seal, the Blocker activates, dissipating ClO2 gas at a safe, carefully calculated rate to sanitize and protect the user.

Once activated, Blocker remains fully effective for 30 days after which its effectiveness gradually lowers. It is active up to 45 days.
Blocker works best in enclosed spaces.

Walking in strong winds, having air conditioning blowing right on you, running and other active pastimes make it hard for Blocker to maintain that clean zone.

If Blocker’s ClO2 gas is unable to collect around you, its effectiveness may be less.

Blocker’s special patent protected ClO2 formulation has undergone various tests in independent laboratories under rigorously controlled conditions to verify its effectiveness and safety for the user.
