Decomposes house dust (mites’ faeces and carcasses) that causes perennial allergic symptoms

It has been confirmed that the Streamer technology decomposes house dust (mite's faeces and carcasses) that causes perennial allergies. It was also found that when year-round allergy and seasonal allergy are combined, allergic symptoms may worsen or develop, but these causative substances are also decomposed at the same time.

Suppresses the deterioration of allergic symptoms caused by mites (faeces and carcasses)

Testing organization

Demonstrated at Yamagata University under the supervision of Professor Shirasawa, Tohoku Bunka Gakuen University

Test method

As a typical causative agent of perennial allergy, the Streamer was irradiated to house dust mite (Dermatophagoides pteronyssinus) at different times. The inactivation rate (the rate of loss of allergic ability) was measured by the allergen activity before and after the irradiation by the ELISA method (a method of detecting and quantifying the ability of an allergen to bind to an antibody by using an enzymatic reaction).

Perennial allergy after 48h of streamer irradiation

As a result of the test, it was confirmed that allergic symptoms caused by mites (faeces and carcasses) were suppressed 99% or more within 48 hours by the Streamer irradiation.

* The results are obtained from demonstration of solely the Daikin Streamer discharge device in an experimental condition.

Suppresses the deterioration of allergic symptoms caused by mites (faeces and carcasses) + cedar pollen

Testing organization

Demonstrated at Yamagata University under the supervision of Professor Shirasawa, Tohoku Bunka Gakuen University

Test method

The house dust mite (Dermatophagoides pteronyssinus) as a typical causative agent of perennial allergy, and the cedar pollen antigen as a typical causative agent of seasonal allergy were irradiated with the Streamer at different times. The inactivation rate (the rate of losing the ability to cause allergies) was measured by the allergen activity before and after the irradiation by the ELISA method (a method of detecting and quantifying the power of an allergen to bind to an antibody using an enzymatic reaction).

Perennial allergy and cedar pollen after 48h of streamer irradiation

As a result of the test, it was confirmed that the 99% or more of the deterioration of allergic symptoms due to mites (faeces and carcasses) + cedar pollen was suppressed within 48 hours after the Streamer irradiation

* The results are obtained from demonstration of solely the Daikin Streamer discharge device in an experimental condition.
