It was found that STREAMER technology decomposes cedar pollen, and at the same time, also decomposes exhaust gases (diesel exhaust particles) and PM2.5 that exacerbate hay fever, dramatically reducing the intensity of allergic reactions.

*This is a demonstration result using a STREAMER discharge device for testing. The effect of the product equipped with STREAMER technology or the effect in the actual use environment may differ.
Pollen + exhaust gas + PM2.5 decomposes at the same time, reducing allergy strength to 92.4%
"As a result of the test, the allergen strength was 2.36 times higher in group D, where exhaust gases and PM2.5 were added to the allergen, than in group A which contained only allergens. It is thought that the simultaneous administration of a mixture of exhaust gases and PM2.5 enhances the immune reaction that causes allergic symptoms such as hay fever. On the other hand, the allergic power of group E exposed to STREAMER for 48 hours was reduced by 92.4% compared to group D.

Testing Organization
Demonstrated at Yamagata University under the supervision of Professor Shirasawa, Tohoku Bunka Gakuen University
Testing Method
Comparative experiments were carried out on 3 groups of mice. (Group A) allergen, (group B) allergen + exhaust gas, (Group C) allergen + PM2.5, (group D) allergen + exhaust gas + PM2.5, (Group E) allergen + exhaust gas + PM2.5 after STREAMER irradiation, given respectively. Administration to mice was continued every 2 weeks, and 8 weeks later, the concentration of IgE*1 antibodies in the mice's blood was measured. We used ovalbumin as an allergen, which is a typical substance used in immunity experiments as an alternative to pollen.
*1: When a reaction with an allergen occurs in the body, IgE antibodies that can only bind to the allergen are produced, and when the reentered allergen reacts with IgE antibodies, various allergy symptoms are produced. Because it is only detectable in very small amounts in healthy people, it is usually used for immunological tests.
Fever development
Adjuvants that worsen allergy symptoms can attach to pollen, which can upset the previously maintained balance and increase the risk of developing hay fever.
