Blocker Cl-40 and Cl-60


What happens when someone catches flu or a cold?

Family members, coworkers, and clients, all become exposed to the virus. 

So, how can we protect ourselves from virus infection and airborne viruses?

Chlorine dioxide can help protect us and our loved ones from infections transmitted by air!

Although there is a word “chlorine” in the name of chlorine dioxide, it is very different from elemental chlorine in its chemical structure and in behavior.  Chlorine dioxide is a small, volatile, and very strong molecule that reacts with other substances by way of oxidation rather than by substitution (i.e., chlorination).

It is well known that chlorine dioxide destroys pathogenic microbes by attacking their cell walls, and interfering with essential protein formation. Chlorine dioxide is a bactericidal agent with a broad action spectrum, whose effectiveness is proven for different classes of microorganisms, including all bacteria, viruses, mold, fungi, algae, and spores.  It is also known that chlorine dioxide is more effective against viruses than either chlorine or ozone. Furthermore, chlorine dioxide is known to be effective against waterborne protozoan such as Giardia Lambia and Cryptosporidium, the causative agents of Giardiasis and Cryptosporidiosis, respectively.  Chlorine dioxide is also very effective against airborne pathogenic bacteria Legionella, the causative agent of Legionnaires’ disease, a severe form of acute pneumonia.

Since chlorine dioxide is an oxidative biocide, microorganisms cannot build up a resistance to it.

In addition to disinfecting water and air, chlorine dioxide eliminates organoleptic problems in air and is a highly effective deodorant.  Because chlorine dioxide is very effective against spore-forming bacteria, it has been used to protect against such dangers as anthrax.

Using unique abilities of chlorine dioxide, a team of scientists of the Japanese company Envroy Co. Ltd has developed portable means for protecting our organism from bacteria and viruses. Together with many public and private research centers of Japan, a series of studies and experiments were carried out, resulting in the development of Blocker Cl-40 /Cl-60, which soon proved to be very effective in field trials.  The uniqueness of the invention is that the main component of Blocker Cl-40/Cl-60, chlorine dioxide (ClO2), Envroy Co. Ltd. managed to place in solid form into an individually sealed aluminum pouch resembling an ordinary office badge. Chlorine dioxide is remarkable because it acts instantly. It blocks the spread and transmission of viruses and bacteria by oxidizing their protein structure. This “ordinary” wonder-badge Blocker Cl-40 (and its modification Blocker Cl-60) kills all known pathogenic viruses, bacteria, fungi, as well as odors and pathogens allergy in the form of pollen at a distance of 1 m3.  One badge is enough for about a month of use.

Envroy Co. Ltd scientists have proved that Blocker is absolutely safe for humans, and can even be used for pregnant women and toddlers! Blocker quickly gained a well-deserved attention in Japan and became a must-use health protection for ordinary citizens as well as representatives of various services – from rescue workers and military personnel to the social and childcare.  Despite the fact that Blocker is manufactured only in Japan, it has gaining popularity around the world, including North America, Europe, Asia, and the Middle East.
