“Ciel Bleu” space sterilization equipment with new technology

Ciel Blue Products handled

If you know that ‘ozone’ kills bacteria and viruses, but are afraid of it because you think it is harmful to humans, we recommend the Coronon Series OH Radical Space Sterilizer ‘Ciel Bleu’.

Please see the video first.

Destroys and removes proteins on the surface of bacteria and viruses.

The highly reactive Free Radicals (O2-, OH-, HOO-, etc.) oxidize the cell membranes of airborne viruses, bacteria, fungi, and other harmful substances. H-drained viruses and other harmful substances are converted to oxygen and water molecules, damaging and destroying their DNA.
Through this process, the harmful substance is inactivated. This is how “Ciel Bleu” is able to kill (eliminate) harmful substances such as bacteria and viruses. 

The test results speak volumes about Ciel Bleu’s performance.

※The efficacy against new coronaviruses is not guaranteed against all mutant strains such as the delta strain and others. Please note that testing is not possible due to the fact that specimens are not available in the private sector.

For everyone’s safety and peace of mind, we conduct performance tests related to sterilization and deodorization at an external inspection agency (Table 1 above is a summary based on such performance tests).

Of course, we also conduct safety tests on the human body.


The amount of ozone emitted, which is harmful to the human body, is 1/30 of the recommended standard. It has also passed the inhalation toxicity test.

Outstanding space purification capability through the generation of ions that are harmless to the human body is realized with high efficiency and low power consumption.

Feature ・Plasma discharge tube construction method (state-of-the-art technology)
・Sterilization and deodorization by radical generation and ion oxidation
・DC power design maximizes safety from electromagnetic radiation
Performance ・Generated ions: OH radical ions with excellent sterilizing power
・Sterilizing ability: bacteria and viruses
・Deodorizing ability: Deodorizes TVOC and toxic gases
・Antioxidant: Preserves freshness of fresh vegetables
・Power supply: DC12V
